Hi Product Hunt! 👋

I built MarginGuard to help small e-commerce merchants make better decisions about promotional discounts.

Different products have different margins, costs, and priorities. A storewide discount might look simple, but it can affect profitability in unexpected ways.

MarginGuard lets you upload a product CSV or try a fictional demo, compare discount plans, protect priority SKUs, and explore suggestions that respect your minimum modeled profit goal.

Everything runs in your browser. No account or financial-data upload is required.

This is a free public beta. It doesn't forecast additional sales from discounts or connect directly to Shopify, so please verify suggested offers against your actual costs and checkout rules.

I'd love to hear from online store owners: what's the hardest part of planning a promotion—calculating costs, choosing discount levels, or protecting specific products?

Thanks for checking it out!
