The Problem
Challenges Businesses Face
These are the pain points our solution addresses.
Building a SaaS product in-house requires hiring 5-8 developers, a DevOps engineer, and a designer — costing ₹50-80 lakhs/year before writing a single line of code.
Most SaaS MVPs fail because founders over-build. They spend 6 months building features nobody asked for instead of validating the core value proposition quickly.
Off-the-shelf platforms (Bubble, no-code) hit walls at scale. They can't handle multi-tenancy, complex permissions, or custom integrations your enterprise clients demand.
Technical debt from early shortcuts costs 10x to fix later. Bad architecture decisions in Month 1 become million-rupee rewrites in Year 2.
Subscription billing is deceptively complex. Usage-based pricing, prorations, dunning, tax compliance (GST), and payment gateway integration require specialized expertise.

Frequently Asked Questions
Everything you need to know about saas application development.
How much does SaaS development cost in India?
SaaS development in India ranges from ₹1,50,000 for an MVP to ₹10,00,000+ for a full-featured enterprise product. JK Tech Hub offers 30-50% savings vs metro agencies. We recommend starting with a focused MVP (₹1,50,000-₹3,00,000) and iterating based on user feedback.
How long does it take to build a SaaS product?
An MVP takes 8-12 weeks. A production-ready SaaS with billing, multi-tenancy, and core features takes 14-20 weeks. A full enterprise SaaS platform takes 20-30 weeks. We recommend launching the MVP early and iterating.
What tech stack do you use for SaaS development?
We use Next.js + React for the frontend, Node.js/NestJS for the backend, PostgreSQL for the database, Razorpay/Stripe for billing, and AWS/Vercel for hosting. This stack is used by successful SaaS companies like Vercel, Linear, and Cal.com.
Can you build a multi-tenant SaaS application?
Yes. Multi-tenancy is our specialty. We implement shared-database with row-level security (RLS) for cost efficiency or schema-per-tenant for strict data isolation. Both approaches scale to thousands of tenants.
Do you help with SaaS pricing strategy?
Yes. We advise on pricing models (flat, per-user, usage-based, freemium) based on your target market, competitor analysis, and unit economics. We build the billing infrastructure to support any pricing model you choose.
What post-launch support do you provide?
3 months free bug-fix support, followed by monthly retainer plans for feature development, infrastructure management, and scaling optimization. Most SaaS clients continue with us for ongoing development.
