About Profit Guard ‑ Protect Margins

Profit Guard checks every discount against your margin rules the moment it is created or updated. If a discount would drop margins below your minimum, the app can disable it, reduce it to a safe amount, or send you a notification to review. You set the rules and choose the enforcement behavior. Product data can come from Shopify, a CSV upload, or a fixed markup percentage. The app includes a discount simulator and built-in A/B testing to compare discount strategies. Auto-disable or reduce discounts that break your margin rules in real time. Flexible rules by collection, product, tag, or store-wide with priority levels. Simulate any discount scenario to preview margin impact before it goes live. A/B test discount strategies and track which discounts perform and earn the most Storefront components like announcement banners, progress bars, and qty buttons. Show more Show less

Simple app that does exactly what it says. Honestly didn't realize how many of our discounts were cutting into profit until I installed this. The cart simulator is handy for testing offers before launching them too. Got personal help during setup which I appreciated as a smaller store. Worth installing.
