B2B SaaS Development DevelopersB2B SaaS
We build B2B SaaS products for businesses. Your MVP ships in 12 weeks with a fixed price.
IRPR builds B2B SaaS platforms for companies targeting other businesses. We use Next.js on the front end, Node.js or Python on the back end, PostgreSQL for data, and deploy on AWS with Docker and Kubernetes.
Every project ships with a fixed price from the Roadmap phase (week 2). Typical budgets range from $80,000 to $250,000 for an MVP. We hit 98% on-time delivery and support SOC 2, HIPAA, and PCI compliance.
Startup CTOs hire us to launch their core product without a full internal team. Mid-market VPs of Engineering use IRPR to replace legacy systems with modern SaaS. SaaS founders get a technical co-founder who delivers code, not decks.

B2B SaaS Development Developers by the Numbers
Every stat here comes from real projects we delivered for B2B companies.
IRPR has shipped over 200 software products since 2017, with more than half being B2B SaaS platforms. Our average MVP delivery time is 12 weeks from kickoff to production launch.
We maintain a 98% on-time delivery rate across all projects. Our client retention rate is above 90%, and the average first-year cost of ownership for an IRPR-built SaaS is under $5,000/month in cloud and third-party services.
B2B SaaS Development: IRPR vs. Generic Dev Shops
Most agencies work hourly and cut corners on compliance. We do it differently.
Generic development shops charge by the hour and often miss security and compliance requirements. They hand over code with no documentation, and you don't own the full IP unless you fight for it in contracts.
IRPR gives you a fixed price from week 2, ships with SOC 2 compliance, and transfers full code ownership at launch. We build on proven stacks so you don't pay for research.
- Bills by the hour with no cap
- No compliance expertise (SOC 2, HIPAA)
- Generic React without server components
- Code IP often shared or unclear
- No CI/CD or monitoring included
- Delays due to junior developers
- Fixed price from Roadmap phase
- Built for SOC 2, HIPAA, PCI out of the box
- Next.js + Node.js with TypeScript
- You own all code and IP
- CI/CD on GitHub Actions + Sentry monitoring
- Senior engineers only (10+ years avg)
Our 4-Phase B2B SaaS Development Process
We move from idea to live product in 12 weeks without scope creep.
Phase 1 is the Roadmap. In week 2 we deliver a fixed-price contract with wireframes, tech stack decisions, and a detailed sprint plan. That holds the budget for the whole project.
Phase 2 is Design and Architecture. Phase 3 is Development and Testing. Phase 4 is Deployment and Launch. Each phase ends with a working increment you can demo.
What Ships with Every B2B SaaS Development Project
Every deliverable is concrete and ready for your team to take over.
You don't get a zip file and a handshake. You get production-grade infrastructure, full documentation, and a deployed app that your users can log into on day one.
All code is in your GitHub repository from the first commit. We set up CI/CD, error tracking, and performance monitoring so you can sleep at night.
- Source code in your GitHub repo with full commit history
- CI/CD pipeline using GitHub Actions
- Sentry error and performance monitoring
- Admin dashboard with user management and analytics
- Stripe/Plaid integration for payments and billing
- RESTful or GraphQL API documentation (Postman/Redoc)
- Load testing report (k6, 500 concurrent users minimum)
- Deployment scripts and runbooks for AWS/GCP
- Unit and integration test suite (80%+ coverage)
- 1-hour code walkthrough and handoff session
