How long does a real CRM take to build?

MVP (login, core workflows, dashboard, 1 integration): 8–12 weeks. Full v1 (mobile, full integrations, role-based permissions, advanced reporting): 16–24 weeks. We ship iteratively — you have a usable system from week 8.

You. Source code in your GitHub from day 1. We can run the production servers (managed) or you can self-host. Even if we part ways, every line of code is yours to maintain or extend.

What tech stack do you use?

Next.js + TypeScript + Postgres + Prisma/Drizzle as a default. Battle-tested, hireable globally (you'll never struggle to find devs), well-documented. If you have strong stack preferences, we adapt.

What about ongoing maintenance and updates?

Optional retainer (~₹40k–₹150k/month depending on scope) covers bug fixes, security patches, small features. Or hand over fully — we document the system and walk your team through it.

Razorpay (UPI / cards / net-banking) or Stripe (international cards). GST-compliant invoices on every payment. One-time projects: 40% on kick-off, 30% midway, 30% on delivery. Subscriptions: monthly or annual in advance.

Can I cancel any time?

Yes. Subscriptions: cancel at the end of the current cycle. One-time projects: see our refund policy — pre-kickoff is 100% refunded, mid-project is pro-rated. We've never made a cancellation hard.
