FAQs

Common questions, straight answers.

How much does a custom web app cost in India in 2026?

MVP web app: ₹12L–₹24L ($14K–$29K) in 10–16 weeks (auth, core workflow, billing, basic admin, prod cloud). Growth-tier: ₹28L–₹55L ($34K–$66K) in 4–6 months (RBAC, integrations, real-time, analytics). Production SaaS: ₹55L–₹1.2Cr in 6–9 months. Enterprise: ₹1.2Cr–₹3Cr+ in 8–14 months.

What stack do you use for web apps in 2026?

Default: Next.js + TypeScript + PostgreSQL on backend, React frontend, Tailwind for UI. Python + FastAPI for data/AI-heavy apps. Laravel + MySQL when budget is tight or operations-heavy. The honest answer: pick what your team can hire and maintain at year 3.

Do you build multi-tenant SaaS from day 1?

Yes — tenant_id discipline from day 1 even if you launch with one tenant. Retrofitting multi-tenancy at year 2 costs ₹15L–₹40L of pain. Building it from day 1 costs ₹1L–₹2L of discipline. We pick shared-schema, schema-per-tenant, or DB-per-tenant based on your isolation needs.

How do you handle billing for SaaS?

Stripe Billing for most cases. Razorpay Subscriptions for Indian customers. Usage-metered billing, proration on plan change, seat-based pricing with overages — all standard. Custom billing engine for non-standard models. GST + multi-currency handled.

What about observability and on-call?

Sentry for errors, structured logging for traces, Datadog/New Relic for metrics. Basic dashboards before launch. Incident response runbooks. Optional 24/7 on-call retainer for production systems.

Will I own the code, schema, CI/CD, and cloud configs?

Yes — every web app build is work-for-hire with 100% source code, DB schema, design assets, CI/CD config, and cloud infrastructure config transferred to your private GitHub or Bitbucket. You can self-host, switch vendors, or licence onward.
