Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureFulfilFlow watches every order against the fulfilment-time target a merchant sets, and flags orders approaching or past that target before they become a problem. It gives the team a worklist they can actually use: claim an order, resolve it, and know it's covered. It separates B2B and DTC performance instead of blending them into one, and sends breach and early-warning alerts to Slack, Discord, or a custom webhook.
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.

- Ranked action list shows orders at risk or breached, most urgent first.
