Deduct Unfulfilled Orders

Subtract pending order quantities from on-hand stock during sync.

When the source-of-truth quantity in your sheet represents physical stock on the shelf, deductUnfulfilled subtracts the units already promised to open orders before pushing the count to Shopify. The number that lands in Shopify reflects what is actually sellable, not what is physically on the shelf.

How it works

Step by step.

  1. STEP 1

    Enable in Sync All

    Turn deductUnfulfilled on alongside your other sync options.

  2. STEP 2

    Sync Master fetches open orders

    Unfulfilled order line items at the target location are summed per variant.

  3. STEP 3

    Sheet quantity − pending = synced quantity

    The result is what gets pushed to Shopify.
