COD Eligibility Rules Engine for Discounted Carts
The Opportunity
An app that lets merchants define cash-on-delivery eligibility based on pre-discount cart value, post-discount value, product tags, customer segments, and custom rules. It prevents COD options from disappearing unexpectedly when discounts or free gifts are applied.
"The merchant’s COD rule is evaluated against discounted totals, causing eligible orders to lose the COD payment option when promotions lower the final price below the threshold."
Market Validation
Detailed Analysis
Proposed Solution
Provide flexible COD rule logic with selectable calculation bases such as subtotal before discounts, subtotal after discounts, shipping-inclusive value, or line-item/category-based thresholds. Include rule priorities and exemptions for gift-with-purchase promotions.
Target Audience
Shopify merchants offering COD, especially in markets with high COD usage and frequent promotions/discounts
Competitive Landscape
Advanced Cash on Delivery apps, COD rule apps, checkout customization apps
Implementation Notes
Use Shopify Functions or checkout validation/rules where available, plus cart and discount metadata to calculate rule eligibility against merchant-selected bases. Support fallback logic for legacy checkout flows, admin rule builder, and test mode so merchants can preview how discounts affect COD eligibility before publishing.
