# What should I do if my inventory is not updating accurately between two Shopify stores?

If your inventory is not matching between two Shopify stores when using Stock Sync, first check whether you are using **Shopify Real‑Time Sync**. This method only updates quantities when a change occurs in the source store and only for changes made **after the feed is activated**. If SKUs have not changed since activation, they will not auto‑sync.

If only some SKUs update or the inventory is still inaccurate, create a separate **Shopify‑to‑Shopify update feed** to force‑sync all quantities. For products missing in the target store, use an **Add feed** to import them before syncing.

Also check the following:
* Ensure the correct **inventory location** is selected when mapping the Quantity field. If the wrong location is chosen, updates will not appear.
* If products are not assigned to the **Online Store** sales channel, make sure the feed’s **Published filter** is set to "Any" so Stock Sync doesn’t treat the store as empty.

If issues persist, provide a sample SKU so the system can verify whether the identifiers match (e.g., unique SKUs required) and whether the correct quantity is being received from the source store.
