Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureDiscount tools control the inputs — a percent off, a code cap, a schedule — but don't check whether the order stays profitable once shipping, fees, and stacked discounts apply. Margin Protector calculates true margin on every cart at checkout using your product costs and the cart's actual discounts, shipping, and fees.
MasterMargins helps merchants price products profitably instead of guessing. Save materials and monthly overhead once, and every product cost updates automatically. Build a full cost breakdown per product and variant, see the suggested price for your target margin, and sync it to Shopify with one click. When a material cost changes, affected products are flagged for review so pricing stays accurate.
