Margin Guard

The POS discount button that knows your margin floor — so your team never discounts past it.

The discount button that knows your margin floor. Set a minimum gross margin once; at the register, Margin Guard shows the cart's live gross margin and the maximum safe discount, with one tap to apply it. When the floor is reached, further discounting stops — your team can still make a deal, they just can't give away margin they can't see. Built for Shopify POS. Pair with Margin Leak to audit discount damage across your orders.

• Live gross margin and product cost for the current POS cart
• Maximum safe discount calculated from your margin floor
• Apply the safe discount directly in Shopify POS
• Discounting automatically stops at your floor
• Simple setup: set margin, add the POS tile, done
