Batch Purchase Quantity Enforcer
The Opportunity
An app that enforces minimum or exact bundle quantities in the cart, such as requiring customers to buy products in sets of 6. It would let merchants build custom mix-and-match boxes while preventing invalid orders from slipping through.
"Merchants need stronger enforcement than ad hoc JavaScript for batch buying rules, because customers can bypass weak front-end restrictions and place invalid orders."
Market Validation
Detailed Analysis
Proposed Solution
Use cart validation, checkout warnings, and product-level quantity rules to require exact multiples, minimum quantities, or bundle counts. Support mix-and-match assortment boxes and highly customizable styling.
Target Audience
Food, supplements, wholesale, beverage, and any merchant selling products that must ship in fixed pack sizes
Competitive Landscape
Bundle apps, quantity rules apps, bundling tools like MinMaxify, order limit apps
Implementation Notes
Implement quantity validation in cart/checkout using Shopify Functions or theme/cart intercepts where supported. Include mix-and-match pack builder, per-SKU or per-collection pack rules, error messaging, and styling customization for theme integration.
