I need an end-to-end seller application that plugs seamlessly into the ONDC Network or hybrid app so that restaurants, cloud kitchens, grocery stores and even full-scale supermarkets can publish their catalogues and start receiving orders inside any ONDC buyer app. Think of the experience sellers get on the Magicpin seller app—that’s the benchmark I’m aiming for, but with the flexibility to set different commission structures for each onboarded business. There should be Different charges for on boarding businesses for different restaurants or supermarket and grocery stores that will be dissussed. and few additional features may add that will be discussed Core scope The app must let sellers: • Add/Edit Menu Items (or product listings) with images, variants and pricing. • Handle Order Management in real time—from acceptance through fulfilment, cancellations and refunds—using ONDC-compliant status callbacks. • Manage payment and logistics inside the same dashboard, with the option to plug in multiple gateway and delivery partners already certified by ONDC. Multiple outlets per brand might be needed later, so please architect the data model with that possibility in mind even though the exact requirement is “not sure” today. Technical expectations – Strict adherence to Beckn protocol / ONDC API specifications, including authentication, lookup, select, confirm, on_* callbacks and settlements. – A lightweight admin panel for me to configure commissions and view health metrics. – Clean, well-documented code (preferred stacks are open, but clarity and maintainability matter more than the language). – Deployment scripts so I can spin up staging and production quickly. Deliverables for acceptance 1. APK / web build ready for Google Play publishing. 2. Source code in a private Git repo with install and run instructions. 3. Postman collection (or similar) proving every ONDC API flow. 4. Short hand-over session plus 30 days of bug-fix support. Only bid if you already understand ONDC’s workflow and can point to at least one live integration. Needed for ios android and web
