Shopify Price & Stock Update

Your store export and the supplier's file are matched by SKU or barcode with configurable normalization (case, leading zeros, dashes, spaces), and the match rate is shown live before anything else happens. New prices come from your rules — cost × markup or cost + amount, with .95/.99 endings always rounded up so the price never falls below cost × margin, plus an optional floor. The update file contains only identity columns plus Variant Price (and Variant Inventory Qty when you enable stock): Shopify keeps every value whose column is not in the file, and all variants of each touched product are included so none can be dropped.

Prices and file contents are processed on this device and never uploaded; supplier cost lists are confidential business data and stay that way. The inventory quantity column applies to single-location stores; the stock option therefore requires an explicit confirmation, and variants without inventory tracking are skipped and listed in the report. The store export should be fresh: the file copies unchanged values verbatim from it, so an old export would write back old data for untouched cells.
