Cart Quantity Tier Discount App
The Opportunity
An app that applies automatic discounts based on the total quantity of items in the cart, regardless of whether the items are the same product or different products. It helps merchants create simple volume-based promotions without manually building complex discount rules.
"Shopify merchants want to discount orders based on the total number of items in a cart, but native discounting and many apps focus on quantity of the same SKU or collection-based rules rather than total cart quantity across mixed products."
Market Validation
Detailed Analysis
Proposed Solution
Provide cart-wide tiered discounts that trigger when total item count reaches configurable thresholds, with support for same-price catalogs, mixed products, and automatic discount application at checkout.
Target Audience
Shopify merchants with fixed-price catalogs, gift shops, curated product stores, bundling-heavy stores, and merchants running bulk-buy promotions
Competitive Landscape
Discount Ninja, Automatic Discounts & Gifts, Quantity Breaks apps, Bundle apps with tiered pricing features
Implementation Notes
Use Shopify Functions or automatic discount logic to evaluate cart line items and calculate total quantity across distinct SKUs, then apply tiered discounts based on merchant-defined thresholds. Key considerations include checkout compatibility, stacking rules, storefront messaging, and edge cases for refunds, edits, subscriptions, and discount exclusions.

"Does anyone know of an app that can handle this? Or is there a workaround within Shopify to implement it?"
Key Pain Points
