How the inventory sync works

The inventory sync keeps Odoo's stock aligned with what the warehouse actually holds - down to individual batch numbers and expiry dates - and leaves an auditable report of every sync it runs. This page explains the two master modes, the two apply modes, what a sync report shows, the special un-batched bucket, and how to force a sync now.

What a sync does

On schedule (default daily) or on demand, the connector pulls the 3PL's full stock snapshot for the mapped warehouse and compares it, product by product and batch by batch, against the warehouse's stock location in Odoo. Every reported (product, batch) becomes a line on an Inventory Sync report (Operations > Inventory Syncs) recording:

  • the Odoo quantity before,
  • the quantity the 3PL reported,
  • the difference,
  • and the action taken (adjusted, staged for review, discrepancy recorded, unchanged, or error - e.g. a SKU with no Odoo product).

Batch numbers the 3PL reports that Odoo has never seen are created as lots on the fly, with expiry dates where the 3PL supplies them. The report header counts adjusted / staged / discrepancies / unchanged / errors so you can read a sync's outcome at a glance, and the whole run is also in the Sync Log with payloads.
