Leading B2B SaaS Development CompanyB2B SaaS
We build B2B SaaS products that scale. 8-12 week MVPs with senior engineers and fixed pricing.
IRPR is a leading B2B SaaS development company. We build multi-tenant SaaS platforms using Next.js, Node.js, PostgreSQL, and AWS. Every project starts with an Idea phase and ends with a production release.
We ship working software in 8-12 weeks. Our fixed pricing starts at $80K for a full-stack MVP and goes up to $250K for enterprise SaaS with compliance (SOC 2, HIPAA, PCI-DSS). You get senior engineers, not juniors.
Founders with a validated idea hire us to build their MVP. CTOs at mid-market companies hire us to rebuild legacy platforms. Product managers at enterprises hire us to launch new internal SaaS tools. We also work with funded startups needing rapid iteration.

Why choose a leading B2B SaaS development company
Building B2B SaaS is different from building a simple website. You need multi-tenancy, billing, compliance, and uptime.
IRPR has shipped over 200 SaaS products. Every platform we build includes tenant isolation, role-based access, and audit logging. We use proven patterns: PostgreSQL for data, Redis for caching, and AWS for infrastructure. Our engineers have built SaaS platforms that handle millions of API calls per day.
We also handle compliance from day one. If your SaaS needs SOC 2, HIPAA, or PCI-DSS, we build the controls in during the Roadmap phase. No retrofitting. That saves you 4-6 months of rework and tens of thousands in audit costs.
The difference between IRPR and a generic dev shop
Most development agencies promise quality but deliver scope creep and technical debt. IRPR is built differently.
We are a leading B2B SaaS development company because we treat your product like our own. Every project gets a dedicated product manager, a senior engineer as tech lead, and a fixed price. We do not use hourly billing. We do not outsource to junior developers.
Our process is transparent. You get a demo every two weeks. You own the code from day one. We deploy to your AWS account. We set up CI/CD, monitoring (Sentry), and error tracking. When the project ends, you have a running SaaS platform and a team that knows how to maintain it.
- Hourly billing with no cap
- Junior developers or offshore teams
- No product strategy, just code
- You own nothing until final payment
- No CI/CD or monitoring setup
- Handoff with no documentation
- Fixed price from the Roadmap phase
- Senior engineers only (10+ years avg)
- Product roadmap and UX design included
- You own the code from week 1
- CI/CD on GitHub Actions, Sentry, Datadog
- Full documentation and knowledge transfer
How we build your B2B SaaS product
Our process is simple: Idea, Roadmap, Product, Release. Each phase has clear deliverables and a fixed timeline.
We start with a two-week discovery phase (Idea). We map your users, define core features, and validate assumptions. Then we create a detailed Roadmap with wireframes, tech stack decisions, and a fixed price. You approve before we write a single line of code.
The Product phase is 8-10 weeks of engineering. We build the MVP, integrate billing (Stripe), add tenant management, and set up analytics. In the Release phase we deploy to production, set up monitoring, and hand over the codebase with documentation.
What you get with every B2B SaaS build
We ship more than code. Every project includes everything you need to run, scale, and maintain your SaaS product.
From day one, you own the code and infrastructure. We deploy to your AWS account. We set up GitHub Actions for CI/CD, Sentry for error tracking, and Datadog for performance monitoring. Your team can take over immediately or we can continue with a maintenance retainer.
We also include a product analytics setup (Mixpanel or PostHog), a billing integration (Stripe), and a user onboarding flow. You get a working SaaS platform that is ready for beta users.
- Source code in your GitHub repo
- CI/CD pipeline on GitHub Actions
- Sentry error tracking
- Datadog performance monitoring
- Stripe billing integration
- Auth0 or Clerk authentication
- PostgreSQL database with migrations
- Infrastructure as code (Terraform)
- Product analytics (Mixpanel/PostHog)
- User onboarding flow
