Why companies choose IRPR as their senior b2b web app development partner
We combine senior talent, fixed pricing, and compliance expertise to ship production-ready apps fast.
IRPR has shipped 200+ B2B web apps for companies in 50+ countries. Each project is built by senior engineers only — no juniors, no outsourced teams. Our clients get weekly demos, a dedicated project manager, and full source code ownership.
Our process starts with a 2-week Roadmap phase where we define the exact scope and give you a fixed price. No hourly billing, no surprise invoices. From design to deployment, the average timeline is 12 weeks.
How IRPR differs from a typical development agency
Most agencies sell hourly billing and junior teams. IRPR is built differently.
The typical dev shop hires junior developers to keep margins high. They bill by the hour, change scope constantly, and deliver late. IRPR does none of that.
We staff every project with senior engineers who have built fintech, healthcare, and SaaS products before. You get a fixed price, a guaranteed timeline, and a clear roadmap.
- hourly billing with no cap
- junior and mid-level developers
- no dedicated project manager
- slow feedback cycles
- no compliance knowledge
- code ownership often unclear
- fixed price from the Roadmap phase
- senior engineers only (10+ years average)
- dedicated PM with weekly demos
- 2-week sprints with fast iteration
- HIPAA, PCI-DSS, SOC 2 built-in
- full source code and IP ownership
Our process for building your B2B web app
Four phases from idea to production, each with clear deliverables and milestones.
We start with a 2-week Roadmap to define scope, architecture, and fixed price. Then we move into design sprints, followed by development in 2-week iterations.
The final phase deploys your app to production with automated CI/CD and monitoring. Every step is transparent and documented.
What ships with every B2B web app engagement
Every project includes these deliverables by default.
You receive everything you need to run and own your app. No hidden fees, no licensing costs.
All code, infrastructure scripts, and documentation are yours from day one.
- Source code in your GitHub repository
- CI/CD pipeline on GitHub Actions or GitLab CI
- Sentry error tracking and performance monitoring
- Automated unit and integration tests
- PostgreSQL database schema and migration scripts
- Dockerized development and production environments
- API documentation (Swagger/OpenAPI)
- Admin dashboard with user management and audit logs
- Deployment runbook and operations guide
