Two-Way Stock Sync

Fulfiro is the source of truth for stock. Here is how the two-way relationship works.

Fulfiro to WooCommerce (outbound)

When you change stock in Fulfiro (manual adjustment, CSV import, PO receiving, bulk update), the new available quantity is automatically pushed to WooCommerce via the REST API. Batch operations use the WooCommerce batch endpoint for efficiency.

WooCommerce to Fulfiro (inbound)

When stock changes in WooCommerce (via another plugin, manual edit, or third party), Fulfiro detects the difference during sync or webhook processing. Instead of silently overwriting, Fulfiro creates a discrepancy alert. You decide which value wins.

Why not auto-overwrite?

If Fulfiro blindly accepted WooCommerce stock changes, it could undo careful inventory counts, warehouse adjustments, or changes from other integrations. The discrepancy alert keeps you in control. See Stock Consistency for the full technical explanation.
