How to keep marketplace and web store stock in sync
A practical checklist for SKU mapping, order events and daily stock reconciliation across sales channels.
· Digital Department
Choose one product identifier
The same product may have different names across channels. Use a unique SKU for each sellable variant, including each size and color combination.
Track every stock event
Reserve stock when an order arrives. Apply cancellation and return adjustments only when their conditions are met. A returned item should not become sellable before it is physically received and checked.
- Verify SKU and variant mapping on every channel
- Confirm order, cancellation and return events reach the integration
- Measure cross-channel update delay
- Set a safety buffer for critical products
Reconcile daily
Compare warehouse, web store and marketplace quantities by SKU. When they differ, inspect the latest order and return events before manually correcting the balance. A manual adjustment alone can hide the underlying issue.
