Margin Owl gives you one place to scan your catalog for prices below cost, stacked discounts, and other pricing issues — so you can spot problems in minutes instead of combing through reports manually.
MarginStack shows contribution margin after discounts, shipping, and goods sold, so D2C teams can see which orders, products, and channels make money.

Reviews, ratings, plans, features and integrations come from each app’s Shopify App Store listing. 28-day figures are labeled when estimated, and a figure that is missing or estimated never decides who leads.
