Hi, I’ve reviewed your requirement and this is a solid Shopify Public App with custom COD flow and tight integration with Shopify APIs. We’ll handle this as a professional team and build a scalable embedded Shopify app that replaces/extends checkout with a smooth COD order form, similar to Relessit but fully customizable. We’ll use React (Polaris + App Bridge) for the frontend and Node.js (Express) for backend, with secure session token auth. The app will inject a “Buy Now (COD)” button on product pages, open a fast, mobile-friendly form, and create orders directly via Shopify Admin API.

We can also integrate WhatsApp/SMS confirmations and optional OTP verification. Code will follow Shopify Public App standards, be clean and well-documented, and ready for App Store submission. Timeline: 12–15 days for full build + testing. Ready to start and share similar app work in chat.

One thing that shapes the whole architecture: are you keeping Shopify's native checkout live for card payments and routing only COD through the custom form, or replacing it entirely? Checkout Extensibility covers the first case cleanly; full replacement also needs an app proxy layer to handle the order submission path. I'd build this as a proper public app with Shopify App Bridge: Node backend handling OAuth and a per-merchant settings panel for required fields and OTP toggle, Checkout Extensibility injecting the COD form at checkout, and an Admin API call to create the order on submit. Pincode-first autocomplete via India Post removes city and state as manual inputs, which cuts the field count from six to four and is the single biggest mobile completion fix on COD flows in the Indian market. M1: App scaffold + OAuth + settings panel, INR 2625, 3d. M2: COD form + pincode autocomplete + Checkout Extensibility injection, INR 2625, 4d. M3: Order creation via Admin API + OTP toggle per merchant, INR 2625, 4d. M4: App Store listing assets + privacy policy + support page, INR 2625, 3d. Do you have an existing Shopify Partners account, or does the app registration need to be set up from scratch?

@Gauravkrpatel01

Hi, This is a solid product idea—COD forms like Rellessit convert really well when built cleanly. I’ve developed Shopify apps with custom order flows, Admin API integrations, and embedded Polaris dashboards, so this fits perfectly. I’ll build a Shopify Embedded Public App (React + Polaris + Node/Express) with a “Buy Now (COD)” flow, dynamic product/variant fetch, and direct order creation via Admin API. I’ll also structure customizable form settings, optional OTP (via SMS APIs), WhatsApp confirmations, and a basic analytics dashboard. Everything will follow Shopify App Store guidelines (auth, billing-ready, scalable code). Flow: App setup → COD form engine → order API integration → dashboard → testing → submission-ready build. Timeline: ~12–18 days. I’ll make this conversion-focused and scalable—do you want the COD form as a popup or full-page replacement for checkout?

@henryn45

Hi, a COD checkout app built to Shopify Public App standards is a serious technical undertaking session token auth, App Bridge integration, and Admin API order creation all have to work flawlessly or merchants won't trust it with their orders. I've built custom Shopify apps where the checkout flow was replaced entirely and the result was cleaner, faster conversions than the default Shopify checkout. Here's exactly how I'll build your app: Frontend: React with Shopify Polaris embedded app UI that feels native inside Shopify admin, fully customisable form fields, colors, and layout per merchant preference. Backend: Node.js/Express clean, scalable architecture handling order creation via Admin API, session token authentication, and optional SMS/WhatsApp confirmation integration. COD Form: One-click Buy Now button on product pages, auto-fetched product details and variants, multi-line address fields, quantity selector orders created directly in Shopify Admin instantly. Analytics: Basic dashboard showing orders, conversion rate, and COD performance metrics merchants can monitor without leaving admin. Delivery: Fully tested on development store, clean documented code, and App Store submission ready within 15-20 days. Bonus features OTP verification and abandoned COD tracking can be scoped into the build if budget allows. Ready to discuss timeline and cost immediately.
