## At a glance

- **Latest version**: 1.3.4 — released 2026-01-21
- **Pricing**: Free
- **Package type**: Magento 2 module
- **Status**: active, accepting new buyers

## Installation

Packagento is licence-gated, so even free packages need a licence on a project before Composer can resolve them.

1. **Sign in or create an account** at https://packagento.com/customer/account/.

2. **Add the package to your account.** Open https://packagento.com/ampersand/magento2-disable-stock-reservation and complete the free checkout. A licence is minted automatically.

3. **Create or pick a project, then activate the licence on it.**
   - Projects represent the Magento installs you deploy to. Manage them at https://packagento.com/projects/.
   - Activate the new licence on the project you'll deploy this package to. Activation is what generates the Composer credentials scoped to that project.

4. **Add the project credentials to your Magento codebase.**

   Grab the project's public + private key from https://packagento.com/projects/ (open the project, then its Credentials tab), and add them to `auth.json`:

   ```json
   {
     "http-basic": {
       "packagento.com": {
         "username": "ppk_live_...",
         "password": "psk_live_..."
       }
     }
   }
   ```

   Add the Packagento Composer repository to `composer.json`:

   ```json
   {
     "repositories": [
       { "type": "composer", "url": "https://packagento.com" }
     ]
   }
   ```

5. **Install and apply.**

   ```bash
   composer require ampersand/magento2-disable-stock-reservation:*
   bin/magento setup:upgrade
   bin/magento setup:di:compile
   bin/magento cache:flush
   ```

## README

[![Build Status](https://app.travis-ci.com/AmpersandHQ/magento2-disable-stock-reservation.svg?branch=master)](https://app.travis-ci.com/AmpersandHQ/magento2-disable-stock-reservation)

This module disables the inventory reservation logic introduced as part of MSI in Magento 2.3.3 - see
https://github.com/magento/inventory/issues/2269 for more information about the way MSI was implemented, and the issues
that can happen with external WMS integrations.

### The Problem

During the order placement and fulfilment processes, Magento's MSI implementation will not decrement stock on order
placement - it will only do so on order shipment and refund.

### Our Approach

This module will:

* Prevent all writes to the `inventory_reservation` table. It does so by using an `around` plugin on `PlaceReservationsForSalesEventInterface`
* Trigger stock deductions on order placement. See `inventory_sales_source_deduction_processor` plugin on `Magento\Sales\Model\Service\OrderService`.
* Prevent stock deductions on order shipment. See disabled `inventory_sales_source_deduction_processor` observer on `sales_order_shipment_save_after` event.
* Replenish stock for cancelled order items. See `inventory` observer on `sales_order_item_cancel` event.
* Replenish stock when a credit memo is issued. See `src/Observer/RestoreSourceItemQuantityOnRefundObserver.php`
  * Requires that "Back to stock" is checked or "Automatically Return Credit Memo Item to Stock" is configured
    * https://docs.magento.com/user-guide/configuration/catalog/inventory.html#product-stock-options
* Truncate (ie, remove all historic entries from) the `inventory_reservation` table upon installation.

### Additional Notes

* Both the `inventory` and `cataloginventory_stock` should be on the same mode (`Update on Save` or `Schedule`) for this module to work as expected. If you are running this on `Schedule` you should have crons activated.

## Quality

Latest release (1.3.4) fails the Packagento QA pipeline. Verdicts below are per-cell (Magento line × PHP version) for the matrixed tools, and run-once for the static / security tiers.


### Compatibility

Each Magento line is installed on its supported PHP versions, then the module is built (DI compile + static-content deploy). Cells show passed / failed / untested; staircase gaps render as `–`.

| Magento | PHP 8.2 | PHP 8.3 | PHP 8.4 | PHP 8.5 |
|---|---|---|---|---|
| 2.4.7 | Pass | Pass | – | – |
| 2.4.8 | – | Pass | Pass | – |
| 2.4.9 | – | – | Pass | 1 |


### Code Quality

Advisory checks against the module's source. Never affect the Compatibility verdict — a phpcs finding can't make a module incompatible.

#### Static Analysis

Coding standards (phpcs), mess detection (phpmd), copy-pasted code (cpd), PHP cross-version compatibility, composer.json validity. Each runs once for the whole module.

| Tool | Status | Findings | Summary |
|---|---|---|---|
| PHPCS | Fail | 43 | 2 errors, 41 warnings (ruleset: Magento2) — 21 auto-fixable with phpcbf |
| PHPMD | Warning | 14 | 14 rule violations (UnusedFormalParameter:10, IfStatementAssignment:2, ExcessiveParameterList:1, UnusedLocalVariable:1) |
| Cpd | Warning | 9 | 9 duplicated chunks spanning 399 total lines (min-lines=5, min-tokens=70) |
| Composer validate | Info | 2 | valid; 2 advisory notes (composer validate --strict) |

#### PHPStan

Type-checks the module against a real Magento install. Re-runs per Magento + PHP version because resolvable symbols differ between releases.

| Magento | PHP 8.2 | PHP 8.3 | PHP 8.4 | PHP 8.5 |
|---|---|---|---|---|
| 2.4.7 | 16 | 16 | – | – |
| 2.4.8 | – | 16 | 16 | – |
| 2.4.9 | – | – | 16 | 17 |


### Tests

Unit and integration suites run per Magento + PHP cell. Test failures speak to the module's behaviour, not its compatibility with a line, so they're reported here separately.

#### Unit Tests

| Magento | PHP 8.2 | PHP 8.3 | PHP 8.4 | PHP 8.5 |
|---|---|---|---|---|
| 2.4.7 | N/A | N/A | – | – |
| 2.4.8 | – | N/A | N/A | – |
| 2.4.9 | – | – | N/A | N/A |

#### Integration Tests

| Magento | PHP 8.2 | PHP 8.3 | PHP 8.4 | PHP 8.5 |
|---|---|---|---|---|
| 2.4.7 | N/A | N/A | – | – |
| 2.4.8 | – | N/A | N/A | – |
| 2.4.9 | – | – | N/A | N/A |


### Security

Dependency-advisory audit (composer audit) plus a source malware scan. A malware detection fails the version outright.

| Tool | Status | Findings | Summary |
|---|---|---|---|
| Composer audit | Pass | 0 |  |
| Malware scan | Pass | 0 |  |

## Licence and pricing

Free. A licence is still minted on checkout and bound to your project for Composer access — no payment step.

Refundable within 14 days of first purchase via https://packagento.com/account/refunds/.

## Install via Claude Code or any MCP client

The Packagento MCP server can run the licence + project + Composer steps above in one tool call:

```
purchase_and_install_packages(
  composer_names=["ampersand/magento2-disable-stock-reservation"],
  project_id="proj_xxx"
)
```

This handles cart, checkout, licence minting, project activation, and writes auth.json credentials. Connect a client with `claude mcp add packagento https://mcp.packagento.com`. Full setup at https://packagento.com/docs/mcp-setup.
