Why does my inventory in Triple Whale differ from Shopify?

Triple Whale’s Inventory Items metric uses Shopify’s Available quantity, which represents stock available to sell. It does not use Shopify’s on-hand total.

The metric reflects inventory from the latest sync, not a continuously updated live count. Sales or inventory changes since that sync can temporarily create a difference from Shopify’s live Available quantity.

Changing your reporting date range does not show historical inventory.

Shopify tracks different inventory quantities. On-hand inventory can include units that are committed to orders or otherwise unavailable to sell.

Triple Whale uses the Available quantity. Comparing it with an on-hand inventory report can produce a difference even when the inventory data is up to date.

Example: A product has 100 units on hand, with 20 committed to orders and no other unavailable stock. Its Available quantity is 80. If Triple Whale’s latest sync captured those quantities, the Inventory Items metric reflects 80 units, not 100.

Triple Whale displays the inventory data received during its latest sync.

If a sale, restock, or inventory adjustment changes Shopify’s Available quantity afterward, Triple Whale may continue to display the previously imported quantity until the data refreshes.

A difference between the two values does not, by itself, mean that the wrong inventory quantity is being used.

The Inventory Items metric shows the latest synced quantity regardless of the reporting dates you select.

For example, selecting last month does not show how much stock you had last month. Use Shopify’s inventory history when you need to investigate past stock levels.

Compare both values as close together in time as possible. Remember that opening or refreshing the Triple Whale page does not establish that a new inventory sync has occurred.

If the difference remains unexplained after comparing the same quantities and accounting for sync timing, contact Triple Whale Support.
