Keeping Shopify inventory trustworthy

Every store eventually discovers the same thing: the stock number in Shopify and the stock on the shelf agree less often than anyone assumed. Fixing the count is easy; keeping it correct is a habit.

Decide who owns the number

If a feed sync app writes quantities from a supplier file, then it owns them — and a manual bulk edit will be silently overwritten at the next sync. Write down which system owns which field before you add a second tool that touches inventory.

Use reason codes every time

Shopify records a reason with each adjustment: correction, received, damaged, quality control, shrinkage, restock, movement. It costs nothing at write time and turns the inventory history into something you can actually audit.

Find the variants that are not tracked

Untracked variants sell infinitely. They are usually created by an import or by someone testing something, and nobody notices until an order arrives for a product that does not exist. Filter for them and decide deliberately.

Decide the policy, not the exception

Continue-selling-when-out-of-stock is right for made-to-order and pre-orders, and wrong for everything else. Set it as a rule across a filtered set rather than variant by variant.

Work location by location

Once stock lives in more than one place, a single total hides the problem: a variant can be comfortably stocked overall and zero at the location that actually ships. Filter on out-of-stock somewhere, and correct one location at a time.

Reconcile in batches you can verify

A stocktake covering the whole catalog produces a number nobody can check. One product type at a time, matched against a physical count, produces corrections you can defend — and a log that explains them later.
