Check your margins before you discount

Introduction

Check your margin before you launch a sale. See the safe discount limit on every variant.

Details

You pick a discount. You pick the lowest gross margin you are willing to keep. PromoMath reads your live prices and cost per item from Shopify and sorts every variant into Safe, Low margin, Losing money, or Missing cost. It also shows the highest discount each variant can take and still clear your floor. Run it on all products, one collection, or a few products. Export the results to CSV. There is nothing to install or sync, and your data stays in Shopify. Requires Cost per item in Shopify.
