IRPR builds B2B SaaS platforms for companies that need a reliable engineering partner. We use React, Node.js, PostgreSQL, AWS, Stripe, and Auth0 to deliver production-ready multi-tenant applications. Every project starts with a 2-week Roadmap phase where we define architecture, compliance needs, and a fixed price.
Our typical B2B SaaS MVP ships in 8-12 weeks with a fixed price range of $80K to $250K. We handle compliance like SOC 2, HIPAA, and PCI-DSS from day one. You get source code, CI/CD pipelines, and error monitoring included.
We work with three types of buyers: Series A startups that need a functional MVP to close their next round, mid-market companies scaling their SaaS product to new verticals, and enterprise teams that need to modernize legacy systems with modern cloud infrastructure.

Why choose an expert B2B SaaS development partner
Building B2B SaaS is different from consumer apps. You need multi-tenancy, billing, compliance, and scalability from day one.
IRPR has shipped over 200 SaaS products across 50 countries. Every project uses a proven architecture: React frontend, Node.js backend, PostgreSQL database, and AWS infrastructure. We include Stripe for billing, Auth0 for authentication, and Sentry for error tracking out of the box.
Our senior engineers average 10+ years of experience. We do not use junior developers or offshore teams. Each project gets a dedicated team of 2-4 engineers plus a technical project manager. The Roadmap phase (week 2) defines every feature, integration, and compliance requirement before we write code.
Generic dev shop vs expert B2B SaaS development partner
Not every agency can build a multi-tenant SaaS platform with compliance and billing. Here is the difference.
Many agencies treat SaaS projects like any other web app. They skip multi-tenancy, use shared hosting, and ignore compliance until it is too late. That leads to costly rewrites and security gaps.
IRPR builds SaaS platforms designed for scale and compliance from the start. We use isolated databases per tenant, deploy on AWS with auto-scaling, and include SOC 2 controls in every project.
- Single-tenant architecture, one client at a time
- No compliance planning until audit time
- Hourly billing with no cap
- Junior developers on the project
- No CI/CD pipeline included
- Code ownership unclear
- Multi-tenant architecture from day one
- SOC 2, HIPAA, PCI-DSS built into the roadmap
- Fixed price per phase, no surprises
- Senior engineers only (10+ years average)
- CI/CD with GitHub Actions and Sentry included
- Full code ownership delivered
Our B2B SaaS development process
We follow a four-phase process that turns your idea into a live product in 8-12 weeks.
Every project starts with a 2-week Roadmap phase. We define the tech stack, compliance requirements, user flows, and a fixed price. No code is written until you approve the roadmap.
After the roadmap, we build the MVP in 6-10 weeks. We deploy to AWS, set up monitoring, and run automated tests. The final phase is release and handover with full documentation and code ownership.
What ships with every B2B SaaS project
Every project includes these deliverables by default. No hidden fees or optional add-ons.
We include everything needed to run a production SaaS platform. From source code to monitoring, you get a complete system. No third-party dependencies you cannot own.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Sentry error tracking and performance monitoring
- Stripe billing integration with subscription management
- Auth0 or Cognito authentication with SSO support
- PostgreSQL database with automated backups
- AWS infrastructure as code (Terraform or CDK)
- Multi-tenant data isolation architecture
- Compliance documentation (SOC 2 or HIPAA controls)
- 30 days of post-launch support
