We build B2B SaaS platforms that ship in 12 weeks. Fixed pricing, senior engineers, and full compliance from day one.
IRPR is a B2B SaaS development firm that builds multi-tenant platforms, subscription billing systems, and API-first products. We use Next.js, Node.js, PostgreSQL, AWS, and Stripe to ship production-ready software.
Every project starts with a 2-week Roadmap phase that produces a fixed-price quote. Most MVPs ship in 8 to 12 weeks. Prices range from $80,000 to $250,000. We handle SOC 2, HIPAA, and PCI-DSS compliance natively.

Why hire a B2B SaaS development firm
Building a B2B SaaS product is different from building a consumer app. You need multi-tenancy, billing, compliance, and scalability from the start.
IRPR has shipped over 200 SaaS products across 50 countries. Every platform we build includes tenant isolation, subscription management, and automated deployment. We use AWS ECS with auto-scaling to handle traffic spikes without downtime.
Our clients typically launch their MVP in 8 to 12 weeks and reach 1,000 active users within 6 months. We provide a fixed price after the Roadmap phase, so you know the cost before any code is written.
The difference between a generic dev shop and a B2B SaaS development firm
Most dev shops build one-off apps. A B2B SaaS development firm builds platforms that scale, bill, and comply.
Generic shops often skip multi-tenancy, billing logic, and compliance because they don't understand B2B SaaS. You end up rewriting the platform after launch. That costs time and money.
IRPR builds all of that into the first sprint. We use proven patterns for tenant isolation, subscription management, and SOC 2 compliance. You get a platform that can go to market immediately.

How we build your B2B SaaS platform
Our process moves from idea to live product in 4 phases. You see working software every week.
Phase 1 is a 2-week Roadmap where we define the architecture, tech stack, and fixed price. You get a detailed document and a clear budget before any development starts.
Phase 2 is development. We work in 2-week sprints with weekly demos. You see real progress and can adjust priorities. Phase 3 is launch prep: load testing, compliance review, and deployment. Phase 4 is post-launch support with 99.9% uptime monitoring.
What ships with every B2B SaaS platform
These are the deliverables you get automatically. No add-ons, no upcharges.
Every platform we build includes a production-ready codebase, automated deployment, and monitoring. You own everything from day one.
We also provide documentation, a CI/CD pipeline, and a 30-day post-launch warranty. Your team can take over or we can continue development.
