PrestaShop Odoo Stock Comparison is an Odoo extension that compares product stock between Odoo and PrestaShop. It extends the Prestashop Odoo Bridge (POB), sold as Odoo PrestaShop Connector.
To start, an admin opens Ecomm Odoo Bridge in Odoo, goes to Mapping, and clicks Compare Stock. A wizard then asks whether to compare all products or a custom range of product IDs.
After the comparison runs, the Stock Comparison list shows the Odoo Quantity and the Prestashop Quantity for each mapped product. Products with a stock mismatch appear in red, and a default filter can list only those products.
From the same list, the admin selects the mismatched products and runs Synchronize Product Stock To Prestashop from the Action menu. The stock level on the PrestaShop end is then corrected in bulk.
This extension supports PrestaShop 1.5 to 8.x with Odoo 8 to Odoo 18. It works as a maintenance module and needs the POB base module installed first.
Additionally, if your PrestaShop store sells in more than one language and you want that data in Odoo, then check Prestashop Multi language Support POB.

Why Do We Need PrestaShop Odoo Stock Comparison?
PrestaShop Odoo Stock Comparison solves a common problem for stores that run the Prestashop Odoo Bridge. Stock in Odoo and stock in PrestaShop can drift apart over time.
Without a comparison tool, the admin has to open each product in both systems and match the quantities by hand. On a large catalog, this check takes hours and still misses some products.
When PrestaShop shows a higher quantity than Odoo holds, buyers can order items that are not in the warehouse. When it shows less, the store stops selling products it can still ship.
This extension puts both quantities in one list and marks every mismatch in red. The admin then selects those rows and sends the correct Odoo stock to PrestaShop in one step.
Also, if you manage more than one PrestaShop shop from the same Odoo database, you can check our extension Prestashop Multishop Extension Odoo Connector.
