The register and the website disagree
Shopify POS and your online store draw from the same inventory, so drift usually has another cause. Canvases put out without being received, an extra location nobody uses, a trunk show rung up on a different device, or products duplicated during an import years ago.
We check every product against what is on your shelves, merge duplicates and set up locations that match how you really work. Your staff get a receiving routine that takes minutes. After that we review counts on a schedule, so drift gets caught in days instead of at inventory time.
