Scope
A custom platform costs ₹5,00,000 to ₹12,00,000 and takes 8 to 16 weeks. That range is deliberately wide because platform scope varies more than any other engagement — I will not quote one without a Diagnostic Sprint first.
Included: authentication and role-based access, Razorpay integration with GST-compliant invoicing, PostgreSQL or Supabase with row-level security, admin and operational dashboards, security hardening, deployment, and 90 days of support after go-live.
Security is not a later phase
Row-level security, parameterised queries, rate limiting and secret handling are designed before the first route is written, not audited in afterwards. On a platform holding customer records and payment data, retrofitted security is how businesses end up on a breach disclosure list.
