Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureMost merchants see revenue, but not real profit. MarginShield calculates the true profit and margin on every Shopify order by combining revenue with product cost, payment fees, shipping cost, packaging, and custom fees. It shows profit right inside the order page and a dashboard, flags loss-making orders, finds products missing a cost, and reveals how discounts and free shipping affect your bottom line.
Profit Guard calculates true net profit on every Shopify order the moment it arrives. Configure your payment processing rate, shipping rate, and COGS ratio once. Profit Guard handles the rest. Orders below your profit threshold are automatically flagged and tagged in your Shopify admin so you can act immediately. The standard tier uses COGS ratio estimation.
