Next Day Shipping Eligibility for Magento 2

Comprehensive stock-aware shipping restrictions in one module.

Two independent rules, one admin section, one license:

1. Next-day eligibility (auto-managed) — removes configured next-day shipping methods from checkout when any cart item is out of stock or otherwise ineligible. Eligibility is auto-maintained by a stock observer; nothing for the merchant to flip per product.
2. Backorder express restriction (opt-in, v1.1.0+) — removes any express methods you list when the cart contains backorder items (out of stock with backorders enabled, or partially short). Useful for merchants who explicitly flag pre-order / made-to-order products and don't want them sold with express delivery.

Both rules raise a single dismissible checkout banner with merchant-customisable wording. Both respect the Drop-Ship Eligible exemption.

Stock-aware. Drop-ship aware. Hyvä compatible. Works with Magento Open Source and Adobe Commerce.

What's new

The version-by-version history lives in CHANGELOG.md. Highlights of the most recent releases:

• v1.4.0 — New per-product Force Standard Shipping Only flag. Tick it on the product edit page (under eTechFlow Shipping) to hard-disable next-day shipping for that product regardless of stock state. For bulky / hazmat / fragile / made-to-order items. Ships with a CLI verification command: bin/magento etechflow:nde:verify --sku=<sku> runs an end-to-end check that the observer + evaluator pipeline is wired correctly.
• v1.3.0 — Module status banner at the top of admin config (shows whether the module is actually active), PDP badge visibility toggle, drop-ship grid filter, inline tooltips on every field.
• v1.2.0 — Shipping method fields are now multi-select dropdowns auto-populated from your active shipping methods — merchants no longer need to know technical codes.
• v1.1.0 — Absorbed the deprecated ETechFlow_BackorderShippingRestrictor module's features as an opt-in "Backorder Express Restriction" toggle. The bundle is now 2 modules (NDE + BackorderEtaDisplay).

What it solves

Merchants who advertise next-day delivery hit the same problem from two directions:

Requirements

Installation

Option A — Composer (recommended)

composer require etechflow/module-next-day-eligibility:^1.1
bin/magento module:enable ETechFlow_NextDayEligibility
bin/magento setup:upgrade
bin/magento setup:di:compile
bin/magento cache:flush

Option B — Manual (from zip)

1. Unzip etechflow-module-next-day-eligibility-1.1.0.zip into:

   <magento-root>/app/code/ETechFlow/NextDayEligibility/
   

   The directory MUST be named ETechFlow (capital E, capital T, capital F) — case-sensitive on Linux servers.

2. Enable and set up:

   bin/magento module:enable ETechFlow_NextDayEligibility
   bin/magento setup:upgrade
   bin/magento setup:di:compile
   bin/magento cache:flush
   

3. Verify:

   bin/magento module:status | grep NextDayEligibility
   

After install — quick setup

Open the admin and go to Stores → Configuration → eTechFlow → Next Day Eligibility.

Step 1 — License

License → License Key: paste the key from your purchase email and save.

Don't have a key yet? Dev/staging hosts are free. Any URL matching localhost, *.test, *.local, staging.*, dev.*, *.magento.cloud, ngrok tunnels, or RFC 1918 IPs runs at full features without a key. For non-standard dev domains, set License → Production Environment = No instead.

Step 2 — Enable the module

General Settings → Enable Module = Yes → save.

Step 3 — Pick your next-day shipping methods

General Settings → Next Day Shipping Methods is a multi-select dropdown. The list is auto-populated from your store's currently active shipping methods (the same list shown under Stores → Configuration → Sales → Shipping Methods). Tick the methods you want removed for ineligible carts — typically just your paid next-day or express options. Hold Ctrl/Cmd to select multiple. Save.

⚠️ Important — keep at least one fallback method unticked. Don't tick every option. The intended pattern is to tick only your paid express / next-day methods so a standard or free option always stays available for ineligible carts. If you accidentally select everything, a safety net returns the original rates and logs a warning to var/log/system.log to prevent a stuck checkout — but that's a guardrail, not a config strategy. See docs/USER_GUIDE.md "Configuration trap" for the typical UK setups.

That's the core feature done. Browse to a product detail page — you'll see the green "Next Day Eligible" / grey "Standard Delivery Only" badge under the price.

Step 4 — (optional) Enable Backorder Express Restriction

If you also want to block express shipping on backorder items:

Backorder Express Restriction:

• Set Restrict Express Methods on Backorder = Yes
• Express Methods to Restrict on Backorder — same multi-select pattern as the next-day field above, but stored independently. Tick whichever methods should disappear when a backorder item is in the cart. Can overlap with or differ from your next-day selection.
• Leave Skip Drop-Ship Products = Yes (default) so drop-ship products bypass this rule.

Step 5 — (optional) Customise the checkout banner

Checkout Notice:

• Show Notice at Checkout = Yes (default)
• Notice Style — warning (amber), info (blue), or error (red)
• Notice Title — bold heading, e.g. "Next day delivery unavailable"
• Notice Message — body copy, e.g. "One or more items in your cart is not eligible for next day delivery."

All four fields can be overridden per store view for multi-brand setups.

Step 6 — (optional) Hide or simplify the product-page badge

General Settings → Show Badge on Product Page:

• Both (default) — green "Next Day Eligible" + grey "Standard Delivery Only" badges
• Eligible only — show the green badge, hide the grey one (recommended if you don't want to draw negative attention to ineligible products)
• Never — no PDP badge at all; the shipping restriction at checkout still works

Per-product overrides (v1.4.0+)

Two checkboxes on the product edit page (under the eTechFlow Shipping attribute group) let you override the auto-calculation per product:

Precedence inside the eligibility evaluator:

1. Force Standard Shipping Only = Yes → always ineligible (merchant override wins)
2. Drop-Ship Eligible = Yes → always eligible
3. Otherwise: stock check (qty > 0 AND in stock → eligible)

Both flags work as Magento mass-action targets — see "Tips" below.

Tips for managing the catalogue

Bulk-flag drop-ship products. In Catalog → Products, filter the grid (now filterable by Drop-Ship Eligible — new in v1.3.0), tick the products, and use Actions → Update Attributes → Drop-Ship Eligible = Yes. Magento applies it to every selected product in one click.

Bulk-flag force-standard-only products. Same workflow with the new attribute: filter by Force Standard Shipping Only = No, narrow further (e.g. by category = "Furniture" or by weight), tick all, Actions → Update Attributes → Force Standard Shipping Only = Yes. Useful for one-pass classification of your bulky-item or hazmat catalog.

Bulk imports. If you're using a CSV import or custom script to load thousands of products, set $product->setData('_etechflow_skip_eligibility', true) before each save to bypass the per-product observer. Then batch-evaluate after the import completes via \ETechFlow\NextDayEligibility\Model\EligibilityEvaluator::evaluateById(...). See docs/USER_GUIDE.md "Bulk imports — the escape hatch" for the full pattern.

Module status banner. At the top of the NDE admin config section is a coloured banner showing whether the module is active, idle, or has a licence problem. Read it first if anything seems off — most "I configured it but nothing happens" cases are answered by that banner.

Changelog — Next Day Shipping Eligibility

All notable changes to this module. Adheres to Semantic Versioning.

[1.6.0] — 2026-05-23 — Close the MSI stock-event propagation gap

A customer found a product (KS00926) with qty=0 but next_day_eligible=1 — the existing observer pipeline never recomputed because the stock dropped to zero through a path that doesn't fire cataloginventory_stock_item_save_after. Investigation showed this is a systematic gap on Magento 2.3+ with MSI installed, affecting most modern stock-change flows.

Root cause

NDE's original observers in etc/events.xml listen for two events:

• cataloginventory_stock_item_save_after — fires on direct legacy cataloginventory_stock_item saves
• catalog_product_save_after — fires on product entity save

On Magento 2.3+ with MSI installed, most stock changes go through Magento\InventoryApi\Api\SourceItemsSaveInterface, which does NOT trigger cataloginventory_stock_item_save_after. The legacy table is updated later by MSI's sync indexer, but that sync runs without firing a save event our observer could hook. Flows that silently bypassed the recompute:

• Order shipment → MSI reservation collapse → indexer-only update
• Refund / credit memo restocking
• Source-items save via REST / SOAP / GraphQL API
• Admin "Manage Stock" screen on a single source
• Bulk import via MSI source-items endpoint

Added

• Plugin/RecomputeOnMsiSourceItemsSave.php — afterExecute plugin on Magento\InventoryApi\Api\SourceItemsSaveInterface. For each saved source item, resolves SKU → product ID and calls EligibilityEvaluator::evaluateById(). Soft-installed: if MSI isn't present (rare on Magento 2.3+ but possible on stripped builds), Magento silently ignores the <type> declaration in etc/di.xml because the target interface doesn't exist — no fatal, plugin just never runs.

• Cron/RecomputeStaleEligibility.php + etc/crontab.xml — hourly safety-net cron. Iterates simple products (up to 5000 per run), calls EligibilityEvaluator::evaluateById() on each. Belt-and-braces backstop for any propagation hole the plugin doesn't cover. Evaluator is idempotent so re-running on a fresh row is a cheap no-op. Schedule: 0 * * * *.

• Console/Command/ResyncEligibilityCommand.php — bin/magento etechflow:nde:resync. One-shot full-catalogue re-evaluation. Supports --sku=A,B,C to narrow to specific SKUs and --dry-run to count without writing. Use cases: cleanup right after upgrading to v1.6.0; manual fix for known-stale SKUs; CI / health-check via dry-run.

Unchanged

• Existing observers (cataloginventory_stock_item_save_after, catalog_product_save_after) stay — they still catch direct legacy saves and product saves. v1.6.0 is purely additive coverage.
• EligibilityEvaluator logic unchanged. Precedence rules (force_standard > drop_ship > supplier > stock) stay identical.
• StockRegistryInterface reads — still legacy. If we find STILL-stale state after v1.6.0, switch evaluator reads to MSI's IsProductSalableInterface as a v1.7 follow-up. Out of scope here.

Migration

composer update etechflow/module-next-day-eligibility
bin/magento setup:upgrade
bin/magento setup:di:compile
bin/magento setup:static-content:deploy -f
bin/magento cache:flush
bin/magento etechflow:nde:resync   # one-shot cleanup of any pre-existing stale rows

The hourly cron takes over from there. No schema changes, no breaking changes.

[1.5.1] — 2026-05-19

Click & Collect / In-Store Pickup filter

For merchants with physical shops. Hides Click & Collect (pickup) shipping methods from any cart whose items lack local stock — independently of the next-day rules.

The Keystation rule that drove it:

Supplier-based drop-ship can keep next-day shipping alive when local stock is zero (the v1.5.0 supplier mode). But pickup is physical — you can't collect what isn't on the shelf. This release adds the matching filter.

Added

• New admin field: Click & Collect / In-Store Pickup Methods (multi-select) under General Settings. Tick which method codes the module should treat as pickup. Companion Custom Click & Collect Method Codes free-text input for codes that don't appear in the dropdown (same merge semantics as the existing Express + Standard custom fields).
• New service method IneligibilityChecker::hasItemsWithoutLocalStock(items): bool — single batched query joining cataloginventory_stock_item for qty + is_in_stock. Treats qty <= 0, is_in_stock = 0, or missing stock row as out-of-local-stock.
• ShippingRestriction plugin now layers the C&C filter on top of the existing next-day filter, in both blacklist and whitelist modes. Pickup methods are stripped whenever any cart item lacks local stock — regardless of whether a supplier-based drop-ship rule would otherwise have made the product next-day-eligible.

Performance

• The local-stock check is only run when the C&C method list is non-empty. Merchants without physical shops pay zero extra DB cost — the filter is short-circuited before any query fires.
• When run, the check is a single batched collection query — same cost shape as the existing hasIneligibleItems check. No N+1 regardless of cart size.

Backwards compatibility

• Default C&C method list = empty. Every existing install behaves exactly as before v1.5.1.
• No new product attributes. No schema changes. No new dependencies.

Migration tip

Stores that already use Click & Collect / In-Store Pickup methods (e.g. Magento's native In-Store Pickup or a third-party module): add their method codes to the new field. From the next stock save, the C&C filter automatically hides those methods on out-of-local-stock carts.

[1.5.0] — 2026-05-19

Supplier-based drop-ship detection

Some stores carry products that are split across multiple suppliers per SKU, where only specific suppliers ship same-day. Keeping the manual Drop-Ship Eligible flag in sync with which supplier currently fulfils each product was a UX trap — one stale value silently turned the next-day badge into a lie.

This release adds an opt-in detection mode that reads the suppliers directly. No store schema is hard-coded: merchants tell the module which product attributes hold supplier state and which supplier names count as same-day. Existing stores see no behaviour change — the default is still the manual flag.

Added

• Drop-Ship Source admin dropdown (under Stores → Configuration → eTechFlow → Next Day Eligibility → Drop-Ship Exception). Two options:
  • Manual flag only (default) — reads the per-product drop_ship_eligible attribute. Identical to pre-v1.5 behaviour.
  • Supplier-based — also checks supplier attributes configured below. The manual flag still works as an override.
• Supplier Attribute Pairs config field — multi-line text, one pair per line in the format active_attr_code:name_attr_code. Tells the module which product attributes hold each supplier slot's active flag + name. Example for a store with three supplier slots: s1_active:s1, s2_active:s2, s3_active:s3. Lines starting with # are ignored as comments.
• Qualifying Supplier Names config field — multi-line text, one supplier name per line. Names are the values your <name> attribute can hold (e.g. Auto remote man, FastFreight Inc.). Match against product data is case-insensitive and trims whitespace.
• New service class Model/SupplierDropShipResolver — the per-request resolver that walks the configured pairs and returns true if any pair has active = 1 AND name is in the qualifying list. Schema-agnostic — works for any merchant's supplier attribute structure. Per-request memoisation keeps the cost low on cascaded saves. Silent failure modes (missing attribute, no config, non-string name value) so a merchant misconfiguration never crashes checkout.
• New source model Model/Source/DropShipSource — backs the dropdown.

Changed

• EligibilityEvaluator::isStockEligible precedence updated to: (1) force_standard_shipping_only wins; (2) manual drop_ship_eligible wins; (3) supplier match wins (only when supplier mode is on); (4) real stock check. The manual flag is always honoured regardless of source mode — admin-set Yes is an override.

Backwards compatibility

• Default Drop-Ship Source = flag. Every existing install behaves exactly as before v1.5.
• The drop_ship_eligible attribute is unchanged and continues to work as a per-product manual override even when supplier mode is on.
• No new product attributes are added by this module — supplier attributes are merchant-owned.

Migration tip

To enable supplier mode on Keystation's setup (three supplier slots S1/S2/S3, with "Auto remote man" being the same-day supplier):

1. Set Drop-Ship Source to Supplier-based.
2. Paste into Supplier Attribute Pairs:

   s1_active:s1
   s2_active:s2
   s3_active:s3
   

3. Paste into Qualifying Supplier Names: Auto remote man.
4. Save. The next time a stock save fires for any product (or on a manual reindex of the catalog), eligibility recomputes against the supplier attributes.

[1.4.3] — 2026-05-16

Unified shipping picker + Standard allow-list mode + plain-language tooltips

Three real merchant issues, fixed in one patch.

Added

• Unified shipping-method source model — all NDE dropdowns now show every shipping option your store offers, including custom-carrier-plugin methods that don't register through Magento's standard list (Hyvä Shipping Page, marketplace shippers, third-party rate engines). Paste a code into ANY of the Custom * Method Codes text inputs and it appears in every dropdown on the page under a "Custom / Additional Codes" group — pick which group it belongs to with the same UI as the built-in carriers. No more "I have 6 methods but only 3 show up".
• Standard / Slow Shipping Methods allow-list (standard_method_codes) — clearer alternative to the original Express block-list. Tick the slow / standard shipping options you want customers to see when their cart can't ship next day; everything else is hidden automatically. Useful when you have multiple "standard" speeds (e.g. Royal Mail Tracked 24, Tracked 48, Free Delivery) and want to enumerate the SHORT list of "things to keep" instead of the long list of "things to hide". Future-proof — adding a new carrier to your store later won't accidentally expose it on ineligible carts.
• Companion additional_standard_codes text input — same merge semantics as additional_method_codes. Codes pasted here count as part of the Standard allow list AND publish into every other dropdown.
• New Model/Source/AllShippingMethods — merges Magento's Allmethods source with custom codes harvested from all NDE additional-codes config paths, de-duped. Used as the source for all three multi-selects.

Changed

• Plain-language tooltips and labels throughout the General Settings group. All technical jargon stripped from merchant-facing copy:
  • "blacklist" / "whitelist" → "block list" / "allow list"
  • "Allmethods source" / "registers through" / "collectRates()" → "shipping options your store offers"
  • "carrier_method" → "shipping option code"
  • "opt-in" / "fallback" / "no-op" → plain English equivalents
  • Field labels rewritten to describe outcome, not internals: "Next Day Shipping Methods" → "Express / Next-Day Shipping Methods", "Additional Next Day Codes (advanced)" → "Custom Express Method Codes", "Standard Methods (whitelist)" → "Standard / Slow Shipping Methods (allow list)", etc.
  • Tooltips now answer "what does this do for my customers?" instead of "what does this do in the database".
• Backorder Express Restriction group — same plain-language rewrite applied.

Implementation

• ShippingRestriction::afterGetGroupedAllShippingRates() now branches: if getStandardMethodCodes() returns a non-empty list AND the cart has ineligible items, it uses the new keepOnly() helper (whitelist semantics) and layers the backorder rule on top. If the standard list is empty, it falls back to the original block-list path — full backward compatibility.
• Safety net unchanged: if any filtering would leave the cart with zero shipping options, the plugin returns the original rates and logs a warning. The whitelist branch has its own warning text ("Standard Methods list does not match any of the carrier rates returned") so misconfigurations are easy to spot in var/log/system.log.

Verified

• 113 NDE unit tests pass — 4 new whitelist-mode tests cover: keep-only-standard-on-ineligible-cart, bypass-when-cart-all-eligible, safety-net-when-whitelist-matches-nothing, layered-backorder-restriction-on-whitelisted-methods.
• setup:di:compile clean (new source model + new constructor injections resolve cleanly).
• PHPStan level 4 clean on AllShippingMethods.php, updated ShippingRestriction.php, and updated Config.php.

[1.4.2] — 2026-05-16

Shipping-method picker UX patch

Three real gaps surfaced by merchant testing of v1.4.1 — corrected.

Added

• New CLI: bin/magento etechflow:nde:list-methods — enumerates every shipping method code visible to NDE's Next Day Methods dropdown (sourced from Magento's Allmethods pipeline), printed as a table or CSV (--format=csv). Solves the "I have 6 methods in admin but only 3 show up in NDE's dropdown" puzzle: the CLI shows you exactly what's available and prints instructions for discovering codes of any custom carriers that register at runtime (Hyvä Shipping Page, marketplace shippers) so you can paste them into the Additional Method Codes field.
• "Clear all" affordance beneath both shipping-method multi-selects (next-day and backorder-express). A red hyperlink under the field that deselects every option in one click. Dispatches a change event so Magento's form-save dirty-tracking sees the reset. Vanilla JS — no jQuery / RequireJS coupling, works on stock admin theme and Hyvä admin theme. Plus an inline italic hint reminding merchants that the native multi-select uses Ctrl / Cmd + click for per-option deselect.
• New Block/Adminhtml/System/Config/Form/Field/ShippingMethodMultiselect — extends Magento's stock Field renderer, delegates element rendering to the parent so the underlying <select multiple> semantics are unchanged, then appends the Clear-all affordance. Wired into both shipping_method_codes and express_method_codes via <frontend_model> in system.xml.

Fixed

• Misleading "info-only" claim removed from the Next Day Methods comment. v1.4.1's comment told merchants that Hyvä Shipping Page entries are info-only content blocks. That was wrong for stores where the Shipping Page module actually registers carriers at runtime via collectRates(). The new comment correctly explains: these methods DO fire as real shipping options at checkout, they just don't surface in the standard Allmethods source — so the Additional Method Codes field (still the right escape hatch) is the way to target them. The CLI command above closes the loop on method discovery.

Verified

• 109/109 NDE unit tests pass
• New ListMethodsCommand registered via etc/di.xml, callable as bin/magento etechflow:nde:list-methods
• New ShippingMethodMultiselect frontend model wired to both multi-select fields — Clear-all link visible underneath, native multi-select semantics preserved
• phpstan level 4 — clean on the two new files

[1.4.1] — 2026-05-16

UX polish patch — closes 8 gaps surfaced by merchant testing

A single focused patch addressing every UX issue raised since v1.4.0 ship. No feature changes, no breaking changes — pure ergonomic improvements to the admin experience.

Added

• Additional Method Codes (advanced) — text input under both Next Day Shipping Methods and Backorder Express Restriction → Express Methods. Lets merchants paste carrier_method codes for custom shipping modules that don't register through Magento's standard Allmethods source (e.g. Hyvä Shipping Page modules where custom carriers live outside the standard carriers/<code>/ config). Merged with the multi-select selection at lookup time.
• isBuyable() method on Block/Product/NextDayBadge — wraps Product::isSalable() for a clean saleability check.
• <tooltip> element on every admin field in system.xml — short hover-help (1 sentence) alongside the existing longer <comment> (paragraph). Reduces "what does this do?" friction.
• Admin stock-state diagnostic notice in UpdateOnProductSave observer. Fires only on adminhtml saves. When a product is saved in a contradictory state — qty <= 0 AND Stock Status = "In Stock" AND Backorders = "No" AND Manage Stock = "Yes" — surfaces an admin notice explaining the consequences and naming the fixes. Drop-ship-eligible products get a more specific warning suggesting Auto-Enable Backorders. Gated to adminhtml area only; cron / API / import saves silently skip.

Changed

• Default label_no value: "Standard Delivery Only" → "Standard Delivery". The "Only" implied a negative framing that read poorly next to the green eligible badge. (Existing installs keep their saved value; only fresh installs see the new default.)
• Grey "ineligible" badge is now hidden when a product can't be added to cart (isBuyable() === false). Previously, an out-of-stock product with no backorders would display "Out of Stock" label AND the grey shipping-promise badge — visually confusing. The badge now suppresses itself when the shipping promise is irrelevant. Green "eligible" badge unaffected.
• EAV attribute notes on drop_ship_eligible and force_standard_shipping_only rewritten with:
  • Full explanation of the side-effects (drop-ship triggering auto-backorders; force-standard overriding drop-ship)
  • The precedence rule (force-standard > drop-ship > stock)
  • Saleability impact (force-standard doesn't affect cart visibility; drop-ship does via the backorder side-effect)
• Multi-select comment text updated to explicitly mention the custom-carrier escape hatch:

  "Custom shipping modules: if your store uses a Hyvä Shipping Page or similar info-only module, its entries are NOT shipping carriers and won't appear here. Only carriers that actually fire at checkout are listed. Use the Additional Method Codes field below for custom carriers outside Magento's standard Allmethods source."

Fixed

• Hyvä Checkout notice now actually renders on mixed-eligibility carts. Previously the customer-facing "Next Day Delivery Unavailable" notice injected into only checkout.shipping.before — a container that exists in Magento's Knockout checkout but is NOT reliably present in Hyvä Checkout (different Hyvä Checkout versions expose different container names). The notice silently no-op'd on Hyvä Checkout one-step storefronts. v1.4.1 references the notice block from THREE Hyvä Checkout containers (before-form-shipping-address, shipping-method-list.before-text, and the legacy checkout.shipping.before fallback). A server-side static guard in hyva-ineligible-notice.phtml short-circuits any duplicate render so only the first container that fires shows the notice — works regardless of which Hyvä Checkout version the store runs.

Implementation

• New Config::mergeCodeSources() private helper. getShippingMethodCodes() and getBackorderExpressMethodCodes() both delegate to it — merge the multi-select primary + free-text additional input, de-dupe, trim, return.
• New Setup/Patch/Data/UpdateAttributeNotesV141.php data patch — idempotent migration that rewrites the EAV note columns on existing installs. Fresh installs get the new notes via the updated AddDropShipEligibleAttribute.php and AddForceStandardShippingOnlyAttribute.php.
• UpdateOnProductSave observer constructor now injects MessageManagerInterface, AppState, StockRegistryInterface. Diagnostic logic gated to Area::AREA_ADMINHTML so no leaked messages outside the admin context.
• NextDayBadge::shouldRenderBadge() now consults isBuyable() for the ineligible-badge suppression.

Verified

• bin/magento etechflow:nde:verify — passes (existing test product behaviour unchanged)
• All 105 NDE unit tests — pass
• setup:upgrade — clean, new migration patch runs
• setup:di:compile — clean (new observer DI dependencies resolve correctly)
• phpstan level 4 — clean

[1.4.0] — 2026-05-16

Added — Force Standard Shipping Only per-product flag

Closes a real gap: a merchant who wants a specific in-stock product restricted to standard shipping (bulky / hazmat / fragile / made-to-order) previously had no way to express that. The auto-calculated next_day_eligible attribute would flip back to "eligible" every time stock saved. v1.4.0 adds a manual override.

• New per-product attribute force_standard_shipping_only — boolean checkbox under the eTechFlow Shipping attribute group on the product edit page. When ticked, the product is always treated as not next-day-eligible regardless of stock state.
• New Setup/Patch/Data/AddForceStandardShippingOnlyAttribute.php — idempotent data patch, fresh installs get the attribute via setup:upgrade.
• EligibilityEvaluator::isStockEligible() now applies a three-step precedence:
  1. force_standard_shipping_only = 1 → always ineligible (merchant override)
  2. drop_ship_eligible = 1 → always eligible (supplier ships direct)
  3. Stock check (is_in_stock = 1 AND qty > 0) → eligible
• EligibilityEvaluator::loadAttributeFlags() — single collection query loads both drop_ship_eligible and force_standard_shipping_only together, saving one DB round-trip per evaluation.
• Observer/UpdateOnProductSave extended to also re-evaluate when force_standard_shipping_only toggles (previously only watched drop_ship_eligible). The backorder-sync side-effect is gated to drop-ship changes only — force-standard doesn't affect saleability, so the merchant's existing backorder settings stay untouched.
• Attribute visible + filterable in the Catalog → Products grid for bulk operations. Magento's standard Actions → Update Attributes mass-action works on it — flip many products at once.

Use cases this unlocks

Changed

• 4 new unit tests in UpdateOnProductSaveTest covering the force-standard precedence (flipped on, flipped off, neither changed, both changed simultaneously).
• New EligibilityEvaluatorTest (11 tests) covering each precedence step + conflict resolution + evaluateById entry point.
• README + USER_GUIDE updated with the new flag and the precedence table.
• Suite count: 172 tests / 230 assertions, all green.

Added — headless verification CLI command

A new console command lets merchants confirm the install is working end-to-end without opening a browser:

bin/magento etechflow:nde:verify --sku=<any-simple-product-sku>

What it does:

1. Captures the product's current force_standard_shipping_only + next_day_eligible values
2. Sets force_standard = 1, saves → observer fires → evaluator runs → DB updated
3. Reads back next_day_eligible and asserts it flipped to 0
4. Toggles force_standard = 0, confirms the evaluator recomputes natural eligibility
5. Always restores the original state (success or failure)
6. Exits 0 on PASS, 1 on FAIL — suitable for CI / monitoring scripts

Output is structured and human-readable so merchants can paste it into a support email if anything fails. Errors point at var/log/system.log and var/log/exception.log for diagnostic details.

[1.3.0] — 2026-05-15

Added — UX overhaul

A round of admin-UX improvements based on first-time-merchant feedback. All backward compatible.

• Module Status banner — a new full-width callout at the top of the NDE admin config section shows the current state in plain language:
  • ✅ Module is active (green) — licence valid + module enabled
  • ⚪ Licence valid, module is disabled (grey) — Enable Module toggled off
  • ⚠️ Licence key missing (amber) — production host, no key entered
  • ⚠️ Licence key invalid for this host (amber) — key entered but doesn't match domain
  • ℹ️ Dev host bypass active (blue) — current host matches *.test/localhost/staging.*/etc.
  • ℹ️ Production Environment = No (blue) — toggle off, licence not enforced
    Each state explains why and what to do, so first-time installers don't have to test checkout to find out whether the module is doing anything.
• PDP badge visibility toggle — new field "Show Badge on Product Page" with three options: Both (default — show eligible AND ineligible badges), Eligible only (green only, hide the grey "Standard Delivery Only"), Never (no PDP badge at all; shipping restriction still works).
• drop_ship_eligible column now filterable in the Catalog → Products grid. Merchants can filter the grid by drop-ship status. New EnableDropShipGridFilter data patch upgrades existing installs; fresh installs get it via AddDropShipEligibleAttribute.
• Inline tooltips on every admin field — expanded the <comment> text on every toggle/dropdown to explain exactly what happens when each option is selected. Customers see "Yes = … / No = …" guidance inline without needing to read external docs.

Changed — defaults

• shipping_method_codes default is now empty (was flatrate_flatrate). The module is a no-op until the merchant explicitly ticks methods. Previously a fresh install with the wrong shipping setup could trigger the safety net immediately and look broken.
• README + USER_GUIDE updated with the new badge visibility setting and bulk-edit guidance.

Implementation

• New Block/Adminhtml/System/Config/ModuleStatus.php renders the status banner; wired via the new module_status group with <frontend_model> in system.xml.
• New Model/Source/BadgeVisibility.php source model + new Config::getBadgeVisibility() method.
• Block/Product/NextDayBadge.php gained a shouldRenderBadge() method; both phtml templates (Luma + Hyvä) now consult it before rendering.
• LicenseValidator::isDevHost() exposed as public so the status block can show bypass status.

[1.2.0] — 2026-05-15

Added — auto-populated multi-select shipping method fields

Merchants no longer have to know or look up their Magento method codes. Both shipping-method fields are now multi-select dropdowns that auto-populate from the store's currently active shipping methods.

• Stores → Configuration → eTechFlow → Next Day Eligibility → General Settings → Next Day Shipping Methods — now a multi-select grouped by carrier ("Flat Rate / Free Shipping / UPS / DHL / …"). Tick the methods you want removed for ineligible carts. List is fed by Magento\Shipping\Model\Config\Source\Allmethods, the same source Magento's core "Allowed Methods" config uses.
• Stores → Configuration → eTechFlow → Next Day Eligibility → Backorder Express Restriction → Express Methods to Restrict on Backorder — same multi-select pattern, separate list.
• Saved values are identical in format (comma-separated method codes), so any merchant who previously typed codes into the v1.1.0 text field sees them pre-ticked after upgrade. No data migration required.
• The safety net introduced in v1.1.0 (return original rates if filter would empty every method) is unchanged — still active, still recommended.

Why

Customer feedback: "How is the merchant supposed to know that 'Free UK Delivery' has the code freeshipping_freeshipping?" Asking the merchant to dig through dev tools, the Sales → Shipping Methods admin, or bin/magento dev:di:info was a real friction point. The multi-select removes the guesswork entirely.

Changed

• etc/adminhtml/system.xml field types updated from text to multiselect for both shipping_method_codes and backorder_restriction/express_method_codes. Labels also shortened ("Next Day Shipping Methods" instead of "Next Day Shipping Method Codes" — codes are no longer a merchant concept).
• Admin field help text rewritten to describe the dropdown interaction.
• README.md and docs/USER_GUIDE.md updated to reflect the dropdown UX. "How to find your method codes" guidance removed (no longer needed).

[1.1.0] — 2026-05-15

Added — "Backorder Express Restriction" (folded in from deprecated BackorderShippingRestrictor)

This release absorbs the entire feature set of the deprecated ETechFlow_BackorderShippingRestrictor
module into NextDayEligibility, eliminating an overlap that previously had two modules filtering
checkout shipping rates on similar conditions. Customers now get one module that handles both
stock-driven next-day rules AND merchant-flagged backorder rules with separate method-code lists.

• New Model/BackorderChecker.php — detects cart items that are out of stock, depleted past min-qty
  with backorders enabled, or partially short. Drop-ship eligible products are exempted by default.
• New admin group: Stores → Configuration → eTechFlow → Next Day Eligibility → Backorder
  Express Restriction with three fields:
  • Restrict Express Methods on Backorder (Yes/No, default No — opt-in)
  • Express Method Codes to Restrict (separate list from next-day codes — e.g. ups_NextDayAir, ups_2DayAir)
  • Skip Drop-Ship Products (Yes/No, default Yes)
• Plugin/ShippingRestriction.php now applies both rules in a single pass: collects the union of
  method codes to remove (next-day codes when ineligibility detected + express codes when
  backorder detected), then filters once.
• Model/ConfigProvider.php and ViewModel/HyvaCheckoutNotice.php show the same checkout banner
  for either trigger. Merchant copy is shared between rules; if you want context-aware messaging
  per rule, raise a feature request.

Why this merge

The deprecated BackorderShippingRestrictor module solved a real problem (block express on backorder
items) but in practice overlapped heavily with NDE's restriction logic — both filtered the same
shipping rates plugin on similar cart-scan conditions. Two notices, two banner stacks, two licence
keys, two sets of admin settings. Customer feedback pointed at the duplication. Folding them into
one module gives merchants a single, comprehensive "shipping eligibility & restrictions" product.

Migration for existing installations

• Before upgrading: copy your etechflow_backorderrestrictor/general/shipping_method_codes value
  into the new NDE field Express Method Codes to Restrict, and toggle Restrict Express Methods
  on Backorder = Yes. Settings do not auto-migrate (different config namespace).
• After upgrading: disable the ETechFlow_BackorderShippingRestrictor module
  (bin/magento module:disable ETechFlow_BackorderShippingRestrictor) and remove its composer
  package (composer remove etechflow/module-backorder-shipping-restrictor).
• The previously-installed BSR's notice/checkout assets will no longer load once disabled.

Bundle

The eTechFlow 3-Module Bundle is now a 2-Module Bundle (bumped to v2.0.0) containing only
NextDayEligibility + BackorderEtaDisplay.

[1.0.4] — 2026-05-15

Added

• Customer-facing checkout notice when next-day shipping is removed because of mixed-eligibility carts. Previously the module silently removed next-day shipping methods at checkout when one or more items in the cart was not eligible — the customer saw standard shipping but had no explanation. Now a dismissible notice appears at the top of the checkout shipping step: "One or more items in your cart is not eligible for next day delivery. Standard shipping options are available."
• Hyvä Checkout support for the notice via a server-side phtml block (Tailwind + Alpine.js, dark-mode + reduced-motion variants, screen-reader announcements).
• Standard Magento checkout support for the notice via a Knockout/UI component (KO template + plain CSS).
• New admin group: Stores → Configuration → eTechFlow → Next Day Eligibility → Checkout Notice with four fields: Show Notice (default Yes), Notice Style (warning/info/error), Notice Title, Notice Message. Each store view can override the wording.
• New Model/IneligibilityChecker.php — shared eligibility-check logic now used by both the shipping-restriction plugin AND the new ConfigProvider/ViewModel, so the notice can never drift out of sync with the restriction.
• New Model/ConfigProvider.php (registered in etc/frontend/di.xml) and ViewModel/HyvaCheckoutNotice.php for the two checkout flavours.
• New Model/Source/NoticeStyle.php source model powering the Notice Style dropdown.

Changed

• Plugin/ShippingRestriction.php refactored to delegate cart-eligibility evaluation to IneligibilityChecker. Behaviour is identical; the EAV query and product-type handling now live in one place.

[1.0.3] — 2026-05-15

Added

• Auto-Enable Backorders for Drop-Ship Products — closes a real UX gap. When a merchant ticks Drop-Ship Eligible = Yes on a product, the module now also sets the product's Advanced Inventory → Backorders to "Allow Qty Below 0" automatically. This keeps the storefront UX consistent: products that display a "Next Day Eligible" badge are also purchasable when local stock is zero.
  Previously, the merchant had to manually enable backorders on every drop-ship product, otherwise customers saw the green eligibility badge but no Add to Cart button.
• New admin toggle: Stores → Configuration → eTechFlow → Next Day Eligibility → Drop-Ship Exception → "Auto-Enable Backorders for Drop-Ship Products" (default: Yes). Set to No if you prefer manual control of backorder settings.
• New Model/BackorderManager.php for safely updating stock-item backorder flags (used internally by the observer).
• 3 new unit tests covering: auto-enable when drop-ship flips on, auto-revert when drop-ship flips off, skip when config disabled.

Changed

• UpdateOnProductSave observer constructor now takes BackorderManager as a 3rd parameter (DI auto-resolves).
• Config model has a new isAutoEnableBackorders() method.

[1.0.2] — 2026-05-15

Added

• "Production Environment" toggle in admin (Stores → Configuration → eTechFlow → Next Day Eligibility → License). Set to "No" on any dev/staging install to run the module at full features without a licence key — useful for non-standard dev domains that aren't auto-detected. Default: Yes. Industry-standard pattern (Amasty, Aheadworks).
• 4 new unit tests covering toggle behaviour: bypass when off, require key when on, default-to-on when unset, off-overrides-valid-key.

Changed

• Admin License section now has two fields: Production Environment (new) + License Key (existing).
• Customer documentation updated to explain the toggle.

[1.0.1] — 2026-05-15

Fixed

• NULL eligibility values now correctly treated as ineligible. Newly imported products with no eligibility evaluation no longer get free next-day shipping until they're stock-checked. (Previously, addAttributeToFilter('next_day_eligible', ['neq' => 1]) silently missed rows where the value was NULL, allowing them through.)
• Parent product eligibility recalc now reads directly from EAV instead of via a product collection. Eliminates a race condition where the catalog flat index could return stale child values mid-save, causing incorrect parent eligibility.
• Shipping rates plugin wrapped in try/catch. A bad EAV query or DB hiccup can no longer crash the customer's checkout — the plugin logs the error and returns the original rates unchanged.
• Grouped product type added to container-types list (was missing — harmless in practice but inconsistent with sibling types).

Changed

• Default value of next_day_eligible attribute is now 0 (was 1). Pessimistic default — a brand-new product hasn't been stock-checked yet, so we shouldn't claim it's next-day eligible.
• drop_ship_eligible attribute group changed to "eTechFlow Shipping" (was "General") — consistent with the sister attribute, easier to find in admin.

Added

• www. prefix normalization in license validation. One key now works for both coolstore.com and www.coolstore.com.
• Expanded dev-host pattern detection — auto-bypass for staging.*, dev.*, qa.*, uat.*, test.*, preview.*, sandbox.* subdomains, hyphen-staging patterns (*-staging.*, etc.), Adobe Commerce Cloud staging (*.magento.cloud), full RFC 1918 IPv4 ranges (10/8, 172.16-31/12, 192.168/16), and developer tunnels (ngrok, loca.lt, serveo).
• Bundle license key support. If you also bought the eTechFlow 3-Module Bundle, one bundle key activates all three modules.
• Bulk import escape hatch. Custom import scripts can set $product->setData('_etechflow_skip_eligibility', true) to bypass the save observer, avoiding 10K observer invocations on large CSV imports.

Composer

• Magento framework version range extended to ^103.0||^104.0 so the same zip installs on Magento 2.4.6 through future 2.4.9+ releases.
