Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureCheckout 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.
Sales and limited drops often attract bulk buyers who eat into your margins. This app caps the discount, not the purchase. Set rules like 10% off up to 5 items per order, or limit the total discount to $20 per purchase. Beyond the limit, customers simply pay full price, and the purchase is never blocked.
- Discount cap: apply tiered discounts that never exceed the limit you set
- Validation: block orders by quantity, product combinations, or required fields
- Payment and delivery rules: hide, rename, or reorder options by order conditions
- Quantity-based volume discounts for B2B and wholesale buyers
- Create discounts based on the quantity of items in the cart.
- Create discounts for products with purchase quantity limits.
- Create discounts for products with a discount amount limit.
- Similar to native discount features, it is easy to set up and manage.
