Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureMargin Guard reads what you paid for each product and what you sell it for, then checks each discount against a minimum gross margin. The discount check shows which variants stay safe, which fall under the floor, and which cannot be checked because the purchase amount is missing. When checkout protection is on, the checkout rule blocks an order that would sell below that floor.
Margin Watchdog checks every order the moment it arrives. It calculates the real margin after stacked discounts, shipping and payment fees, then tags the order LOSS or LOW_MARGIN when it falls below the floor you set. You get an instant email and Slack alert, and one daily digest at 08:00 in your store's time zone.
