Sphior Margin: Discount Cap

Checkout quietly leaks margin: promotions stack past your limit, reps over-discount, and loss-making orders slip through. Sphior Margin stops the bleeding with Shopify Functions — capping discounts so they never exceed your limit, blocking carts that break your rules, and controlling payment and delivery by order conditions. It then measures the over-discount prevented from your real orders and shows it on a dashboard, kept separate from estimates so the numbers stay honest.
