Hi there, Thanks for the detailed information. I can build your backend for the Car Spare Parts Multi-Vendor Marketplace, covering everything from NBFC credit integration and smart shipping to number plate-based vehicle lookup and merchant billing workflows. I’ll handle all server-side modules—authentication, user/merchant management, product & inventory, billing, shipping, wallet & loan system, payment routing, and dashboards for merchants, customers, and admin—using Node.js with NestJS and MongoDB/PostgreSQL, with Redis for caching and queuing to ensure smooth performance. I will integrate third-party APIs like number plate recognition, Porter/Shiprocket for shipping, PDF invoice generation, and NBFC credit approval, ensuring all workflows—payments, commissions, wallet usage, and loan repayments—are automated and reliable. I’d like to clarify a few details, such as expected daily order volume, NBFC workflow preferences, and hosting setup, so I can provide a detailed plan with modules, milestones, timeline, and cost. Thanks, Rahul A.
