Smart Discount Cap Manager
The Opportunity
An app that caps percentage discounts by dollar amount or cart rules while keeping Shopify checkout totals accurate. It helps merchants run aggressive promotions without accidentally over-discounting or displaying incorrect totals.
"The merchant needs a maximum discount cap for percentage discount codes, but the current Script Editor-based workaround shows incorrect totals in checkout even though line items look correct."
Market Validation
Detailed Analysis
Proposed Solution
Offer rule-based discount caps, proportional allocation across line items, and checkout-safe calculations that preserve accurate subtotal, discount, and total display.
Target Audience
Shopify merchants running promotions, tiered discounts, or capped coupon campaigns
Competitive Landscape
Discount Ninja, Bold Discounts, Seguno, Automatic Discount apps, Shopify Functions-based discount apps
Implementation Notes
Implement with Shopify Functions or discount-function logic rather than legacy scripts; support max discount ceilings, percent-to-fixed conversion, cart-rule conditions, line-item apportionment, and accurate checkout/order summary recalculation with testing across discount combinations.

"Is there anyway to correct this?"
