Inventory syncing for Shopify Fulfillment Network
Keeping accurate records of the current state of your inventory helps your orders to be fulfilled efficiently and helps you to plan for the inventory that you'll need in the near future.
To ensure that Shopify Fulfillment Network (SFN) inventory levels match your own inventory levels, an inventory sync is performed periodically. There are two inventory syncing methods that can be used:
- delta sync
- override sync
If you aren't sure which sync you're currently using for your SFN inventory location, then contact the Fulfillment Success team through the Overview tab in your SFN app.
When a new SKU is sent to SFN in an inbound transfer, the fulfillment center approves and verifies it for fulfillment. Learn more about finding the available inventory amounts in your Shopify admin.
If your store uses the delta sync method, then the Available quantity at the Shopify Fulfillment Network location in your Shopify admin is updated each time an order is placed. If there are adjustments at the fulfillment center, such as for miscounts, damaged products, or special projects, then the adjustment is applied to your Available inventory that evening.
SFN never automatically overrides the Available quantity. If you make manual changes to it, then your new inventory levels will probably be incorrect.
When a SKU is sent to SFN in an inbound transfer, the fulfillment center approves and verifies it for fulfillment. After the SKU is verified, the Available inventory for the Shopify Fulfilment Network location in your Shopify admin is updated.
If your store uses the override sync method, then your Available inventory is recalculated at various times as changes happen to your SKUs, such as every time an order for that SKU is created or edited. In this case, you can't make changes to inventory quantities for the Shopify Fulfillment Network location in your Shopify admin without them being overwritten.
