Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featurePaid orders get stuck when a 3PL, shipping or order management app stops syncing, and nobody notices until the customer asks where the parcel is. Order Sync Watchdog watches every paid order and emails you when one stays unfulfilled past the window you choose: 6, 12, 24 or 48 hours. It listens to Shopify order updates and re-checks every 15 minutes, so a missed update never means a missed alert.
Overdue Owl tracks every fulfillment order against your ship deadline and alerts your staff once when it's actually late. The clock starts when a held or scheduled pre-order is released, not when it was placed, so released pre-orders aren't flagged the moment they return to Unfulfilled. Each order gets one alert per rule, with a full trace showing why it was or wasn't flagged.
- Email alert when a paid order passes your fulfillment window
- Choose a window of 6, 12, 24 or 48 hours
- Background re-check every 15 minutes catches updates Shopify missed
- One list of every order past its window, linked to the order
- One alert per order, never repeated every time rules run
- Clock starts at hold release or scheduled-ready date, not at checkout
- See exactly why any order was or wasn't flagged, with a full trace
