SaaS Product Development
From idea to recurring revenue — multi-tenant SaaS built end to end.
Overview
Turning an idea into a subscription business takes more than code, and BetaZen builds the whole machine: multi-tenant architecture on Next.js and Node.js, Stripe and Razorpay billing with plans and usage metering, admin consoles, onboarding flows, and the product analytics that tell you what to build next. Zero-downtime deployments and tenant data isolation come standard.
We have helped founders from Kolkata’s startup ecosystem take SaaS products to paying customers across India and abroad, and we build for overseas founders who want Indian engineering economics without compromising quality.

Technologies we use
Why choose BetaZen
Revenue plumbing done right
Trials, upgrades, proration, dunning, and GST-compliant invoicing are wired in from launch, so monetisation never blocks growth.
One instance, every customer
True multi-tenancy keeps infrastructure costs flat as sign-ups climb, protecting margins instead of eroding them.
Instrumented for learning
Activation, retention, and churn events are tracked from the first release, giving you real data for the next roadmap call.
How we work
Discovery & Strategy
We start by understanding your goals, users, and constraints, then map the fastest path to measurable outcomes.
Design & Architecture
We design the experience and the system architecture up front so what we build scales cleanly and predictably.
Agile Delivery
We ship in short, reviewable increments with continuous testing so you see working software early and often.
Launch & Support
We handle deployment, monitoring, and handover — and stay on to iterate, optimize, and support post-launch.
Frequently asked questions
I am a founder in Kolkata — can we build my SaaS together in person?
Yes, and it is one of our favourite ways to work. Kolkata founders regularly co-work sprint plans and demo days at our office, keeping the product loop tight while our engineers handle the build.
How much does it cost to build a SaaS MVP?
A revenue-ready MVP — auth, billing, core feature set, admin panel — typically runs ₹4–10 lakh depending on complexity. We scope a version that can charge customers early, then fund iteration from real feedback.
Can you handle both Indian and international payments?
Yes — we implement Razorpay for INR and UPI flows alongside Stripe for global cards, with currency handling, GST invoices, and export-compliant billing configured per market.
Will the platform survive rapid user growth?
The architecture is stateless and horizontally scalable from day one, with Redis caching and managed Postgres. Scaling to more tenants is a capacity change, not a rewrite.
