Best B2B Web Development VendorWeb Development
Senior engineers build your B2B web app in 8-12 weeks. Fixed price, no surprises.
IRPR is the best B2B web development vendor for companies that need production-grade web apps built by senior engineers. We use Next.js, React, Node.js, Python, and PostgreSQL to ship scalable, secure applications.
Every project starts with a 2-week Roadmap phase for a fixed price of $8,000. Full MVP builds range from $80,000 to $250,000 and take 8-12 weeks. We handle compliance for HIPAA, PCI-DSS, and SOC 2 out of the box.
We work with CTOs who need to launch a B2B SaaS platform, product managers who need a custom portal for enterprise clients, and founders who need a scalable MVP to raise Series A. Each gets a dedicated senior engineer team.

How we differ from other B2B web development vendors
Most agencies bill hourly and change scope. We don't.
Generic dev shops often start with a vague estimate and add fees for every change. They use junior developers and outsource testing. You end up with a buggy app and a blown budget.
IRPR gives you a fixed price after the Roadmap phase. You get senior engineers who write tests, deploy to production, and hand over full ownership of the code.
- Hourly billing with no cap
- Junior developers on your project
- No compliance expertise
- Scope creep charges for every change
- No CI/CD or monitoring setup
- Code ownership often unclear
- Fixed price after Roadmap phase
- Senior engineers only (10+ years avg)
- HIPAA, PCI-DSS, SOC 2 built in
- Scope locked in Roadmap, no surprises
- CI/CD pipeline on GitHub Actions, Sentry monitoring
- Full code ownership transferred to you
