I need a solid, web-based medicine billing and ERP solution tailored for a small chain of pharmacies. Core modules must cover GST-compliant billing, batch-wise inventory with expiry and stock alerts, customer and supplier records, purchase and sale returns, and a report suite that lets me track daily sales, profit margins, and ageing stock at a glance. Multi-user, multi-pharmacy support is essential because several counters will run simultaneously. The system has to expose clean REST APIs so it can sync seamlessly with my existing medicine delivery app. I am open to React or Angular on the front end and Node, Laravel, or another proven back end paired with MySQL—just keep the architecture scalable, secure, and thoroughly documented. Think of Marg ERP, Vyapar, or MyBillBook as the benchmark for speed and usability, but with a lighter, modern UI. I expect: • An MVP that my pharmacists can start using within 30 days (full rollout 45-60 days). • A separate admin dashboard for configuration, user roles, and pharmacy onboarding. • Well-commented code in a private Git repo plus setup and user documentation. • Optional post-launch support and feature iterations, which we can scope after delivery. If you or your team have shipped similar SaaS or desktop ERP products and can commit to a fast, reliable roadmap, let’s talk details and milestones right away.
