Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureThe average store runs 6–8 paid apps and loses track of the bill. Watchdog maps your whole app stack in seconds: spot duplicate apps doing the same job, find lower-cost swaps, and see invoice-confirmed spend per app. It even flags apps that bill you but never load on your storefront. Audit your stack, cut what you don't need, and stop overpaying — without guessing what's safe to remove.
Supplier Trust turns every supplier invoice into an audit. Upload an invoice (Excel, CSV or PDF) and it auto-detects the columns, splits combined "set" lines into individual products, and matches each line to your real Shopify orders. It then flags overcharges, cost and shipping increases, duplicate orders billed twice, missing refunds you were owed, and commission mismatches.
