WooCommerce Allegro Stock Sync

Client

A client selling in parallel through a WooCommerce store and on Allegro. Stock discrepancies were causing overselling and canceled orders.

Challenge

The WP Desk WooCommerce Allegro plugin didn't offer automatic stock sync from Allegro back to WooCommerce. Selling on both platforms at once, the client kept hitting overselling — products sold on Allegro still showed as available in the store. They needed a solution that handles multiple Allegro accounts at once, with smart conflict resolution.

Solution

We built a custom WordPress plugin (an add-on for WP Desk Allegro) that implements full two-way sync. Key elements: (1) listening for OFFER_STOCK_CHANGED events from the Allegro API with incremental change polling; (2) support for multiple Allegro profiles with timestamp-based conflict resolution; (3) a configurable stock priority (Allegro vs WooCommerce); (4) automatic mapping of Allegro shipping classes to WooCommerce; (5) filtering Allegro orders from the WooCommerce panel and the REST API; (6) sync via WordPress Cron plus a manual trigger from the admin panel with a change preview. All of it backed by detailed PSR-3 logging for multi-account debugging.
