MarginSentry launched on October 6, 2026. Shoplist is watching for its first storefront installs and tracking pricing in the meantime.
Supplier price lists, margins, purchase orders and stock in one app. Every write is verified.
Your supplier sends a new price list and you discover the increases on your invoices. MarginSentry reads the file, CSV or Excel in any layout, matches each line to your catalogue, shows the margin after per product, and writes the new costs to Shopify only when you confirm. Each write is read back and can be undone in one click. It also runs your purchasing: purchase orders as PDF, scan to receive with landed cost, reorder points, sales forecasts, stocktakes, transfers and reports.
Every number on this page comes from public storefront scans and the public Shopify App Store listing. If Shoplist shows MarginSentry on a store, it is there.
