Why companies choose IRPR for B2B web app development services
We deliver production-ready B2B web apps in 8-12 weeks with a fixed price.
Most agencies charge by the hour and scope creeps. IRPR gives you a fixed quote after the Roadmap phase (week 2). You know the exact cost before we write a line of code. No surprises.
Our senior engineers have shipped 200+ products across 50 countries. We use Next.js, Node.js, PostgreSQL, and AWS with CI/CD on GitHub Actions. Every project includes Sentry error tracking, Datadog monitoring, and a 99.9% uptime SLA.
How IRPR delivers B2B web app development services differently
We replace unpredictable agency chaos with a fixed-price, senior-only team.
Generic dev shops assign junior developers who learn on your dime. They bill hourly and stretch timelines. IRPR assigns a team of senior engineers with 10+ years of experience each. No juniors. No hourly billing.
We follow a four-phase process: Idea, Roadmap, Product, Release. In the Roadmap phase (week 2), we produce a detailed spec with wireframes, tech stack, and a fixed price. You approve before we build.
- Hourly billing with no cap
- Junior developers learning on your project
- Scope creep without change orders
- No compliance expertise
- Unclear timeline
- Code quality varies
- Fixed price after Roadmap phase
- Senior engineers with 10+ years experience
- Scope locked in week 2
- HIPAA, PCI-DSS, SOC 2 built-in
- 8-12 week timeline guaranteed
- Full source code ownership
Our process for building your B2B web app
Four phases from idea to production in 8-12 weeks.
We start with a 1-2 week kickoff to align on goals, users, and compliance needs. Then we move into the Roadmap phase where we produce a detailed spec with wireframes, data models, and a fixed price.
After you approve the Roadmap, we build the product in 8-12 weeks. We deploy to a staging environment, run load tests, and hand over full source code. You own everything.
