See every featureChecking every order by hand stops being realistic as volume grows. Order Checker runs your rules on every order and lists only the ones that need a look, with the reason attached. A finding places a fulfillment hold. It clears when every reason in that category is reviewed, so a person always makes the call.
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.
- Lists only the orders needing review, longest-waiting first, with the reason
- Places a fulfillment hold; it clears when that whole category is reviewed
- Turn each of the 26 checks on or off and set your own thresholds (Starter: 5)
- Finds where your scheduling app stores delivery dates, with no per-app work
- 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
