Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureDiscount Guardian shows the net profit of each discount code after product cost, shipping, and payment fees. Each code is marked Keep, Review, or Stop against the margin floor you set. You get an alert when a code drops below that floor, and you can see which products lose money at a chosen discount percent. At checkout, those products can be left out of the discount so the promotion does not cut into profit.
Offerproof is a read-only monitor for your discounts. It scans on demand with Scan now, or every day, and checks for app-created discounts with no end date, codes near their usage limit or redeemed far above usual, codes the same customer can reuse, automatic discounts that combine with each other, and a discount or combination that prices a variant at zero. Each finding names the discount and the setting to review.
- Calculate net profit for each discount using costs, shipping, and fees.
- Review discounts with Keep, Review, or Stop margin status.
- Get alerts when a discount falls below your margin threshold.
- Find products with low or negative margins after discounts.
- Finds app-created discounts with no end date that keep running unnoticed
- Warns when a code nears its usage limit or is redeemed far above its usual pace
- Shows automatic discounts set to combine, so they apply to the same order
- Catches discounts that, alone or combined, price a product variant at zero
