Catch the inventory your sync apps got wrong — before a customer does.
Inventory sync apps fail quietly. The app reports success, your stock numbers sit frozen or get reset, and the first sign of trouble is a customer ordering something you do not have.
Read-only. It never writes to your store.What it looks like when it fires
ExampleCeramic Mug · 11ozMUG-11-WHT
Your store now shows 28 available
Thane Warehouse was set to 18. If that number was meant store-wide, you are overstated by 10.
Changed
Thane Warehouse: 8 → 18
Unchanged
Mumbai Store: still 10

Shopify totals your locations, so the storefront shows 28 and nothing anywhere warns you that only one warehouse was written.
What it catches
One location updated, the others left behind
A sync writes one warehouse and leaves the rest on old numbers. Shopify adds them together, so the total looks perfectly normal and nothing warns you. SyncCheck tells you what your storefront is now advertising, and by how much it is out.
Numbers that have stopped moving
Stock that has stopped updating looks exactly like stock that simply has not sold. SyncCheck shows how long it has been since each product last actually changed, and flags a location that stayed flat while the others moved.
Quantities that do not look real
A count quietly reset to zero. A placeholder like 999 sitting where a real number should be. The same quantity on every variant of a product, which is the signature of a number pushed rather than counted.
Who made the change
For anything it flags, SyncCheck links you straight to Shopify’s own inventory history for that product, so you can see the adjustment and where it came from.
What it does not do
Worth knowing before you decide, rather than after.
It never writes to your store.
It is read-only. It cannot change your inventory, your products or your prices, because it does not hold the permissions to do so.
It does not watch continuously.
It checks when you run a check. There is a button for that, and you can press it whenever you want.
It cannot name the app that made a change.
Shopify does not expose that through its API, so nothing can. This is why it links you to Shopify’s own history instead of guessing.
It does not fix your sync app.
It tells you sooner when the app has gone wrong. That is the whole job.
Where this is up to
SyncCheck was built after reading through several hundred reviews of the major inventory sync apps. The same handful of failures came up again and again, always with the same ending — the merchant was the last to know. Every check on this page exists because a real shop owner described losing money to it.
It is early, and it is free for the first stores to come on board.
Connecting a store takes about five minutes
You create a custom app in your own Shopify admin and give it three read-only permissions. You keep control of it, and revoking access is one click in Shopify that takes effect immediately.
