Feedstead prepares Shopify product-price updates from supplier cost spreadsheets. It matches a supplier CSV or XLSX price list to a current Shopify product export by exact SKU, calculates proposed prices using markup and rounding rules, and shows current and proposed values for review. Users choose which changes to export, with separate approval for large changes. Feedstead generates a CSV that the user imports into Shopify; it does not connect to or update a store directly. Files are processed in the browser. The free version supports up to 200 supplier rows without registration. Workspace supports up to 50,000 rows, local client profiles, reusable supplier column mappings, and backup and restore. Saved settings remain on the device; signing in restores paid access, not files or saved configurations.
