Built for Shopify merchants

Shopify-native
Built for margin-conscious merchants

Most promotions look profitable. Most aren't.

PromoLens connects to your Shopify store and shows you what your promotions actually did to margin — not just revenue. Then it helps you forecast and plan the ones worth running, before you commit to them.

The difference between a good promotion and a margin killer is data. Now you have it.
