Releasit COD Fee & Verify

Full Stack Developer

Built for Shopify

Set COD fees, discounts, and conditional rules by country, product, or order value. Verify orders with WhatsApp OTP to block fake checkouts and reduce RTO. Collect partial COD payments upfront with full payment tracking and balance visibility. Built as part of the Releasit team at Shop Circle.

Cash on delivery moves the risk onto the merchant: the order is placed before any money changes hands, so fake and impulse orders turn into returns to origin — stock shipped, courier paid, nothing collected. The app works on that from both ends, pricing the risk through conditional COD fees and removing it through verification before an order is accepted.

Rules can key off country, product or order value, WhatsApp OTP confirms the buyer is real, and partial upfront payment turns a pure-COD order into one the merchant is already part-paid for, with the remaining balance tracked through to delivery.

Same architecture as the order form it sits alongside: an embedded Remix admin on Polaris and App Bridge with Tailwind, Liquid on the storefront, Shopify's GraphQL and REST Admin APIs for data, DynamoDB for storage, and AWS with Docker and CloudWatch underneath. Tested with Vitest.
