Trigger-Based Cart Discount for Specific Product Triggers
The Opportunity
An app that automatically applies a percentage or fixed discount to all non-trigger items in the cart when a designated product is added. This solves a common promotional workflow that standard bundle and BOGO apps often cannot handle without manual bundle construction.
"The merchant wants a rule where adding Product A triggers an automatic discount on all other cart items, without requiring discount codes or manually added bundle components."
Market Validation
Detailed Analysis
Proposed Solution
Provide cart-level conditional discount logic using Shopify Functions or app-managed automatic discounts, letting merchants choose trigger products, discount scope, excluded collections, and discount type.
Target Audience
Shopify merchants running promotions, cross-sell offers, and conditional incentives on non-Plus plans
Competitive Landscape
Common bundle apps, BOGO apps, automatic discount apps, discount logic apps, some Shopify Functions-based discount apps
Implementation Notes
Build a discount rules engine around trigger products and cart contents, using Shopify Functions for automatic discount calculation where available; support exclusions, stacking rules, partial carts, collection filters, and clear storefront messaging so merchants can explain why discounts activated.
