Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureB2B Guardrail scans your store's B2B configuration and alerts you when wholesale rates, catalogs, or discount codes become visible to retail shoppers. It checks B2B catalogs, discount codes, and automatic discounts across 8 scenarios, ranks findings by severity, and links you directly to the fix in your Shopify admin. Your store gets a protection score from 0 to 100 that updates with every audit.
Discount 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.
