Why choose a premium B2B web app development vendor?
Most agencies deliver on time but miss on quality. IRPR delivers both.
A premium vendor brings senior engineers who have built 200+ products across 50+ countries. They know how to design scalable architectures that handle 10x growth without rewrites.
With IRPR, you get a fixed price and a clear timeline from day one. We use React, Node.js, and PostgreSQL for most projects, and can add any integration your business needs.
The difference between a generic shop and IRPR
Not all web development vendors are created equal. Here's why IRPR stands out.
Generic dev shops often use junior developers, hourly billing, and no compliance standards. Projects run over budget and over time.
IRPR assigns only senior engineers, uses fixed pricing after the Roadmap phase, and builds compliance (SOC 2, HIPAA, PCI) into every project from the start.
- Hourly billing with no cap
- Junior or mid-level developers
- No compliance certifications
- Unclear timeline or scope creep
- Code ownership unclear
- No post-launch monitoring
- Fixed price after Roadmap phase
- Senior engineers with 10+ years each
- SOC 2, HIPAA, PCI-DSS built in
- 8-12 week timeline, 98% on-time
- Full code and IP ownership
- Sentry monitoring and 99.9% uptime SLA
How we deliver your premium B2B web app
Our 4-phase process ensures clarity and speed from idea to launch.
Every project starts with a 2-week Roadmap phase where we define scope, architecture, and price. No code until you approve.
Then we build iteratively with weekly demos, so you see progress and can pivot fast. Deployment includes CI/CD and monitoring.
What ships with every project
You don't just get a web app. You get everything needed to run and maintain it.
Our deliverables go beyond code. We include documentation, tests, monitoring, and deployment scripts so your team can take over immediately.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions or CircleCI
- Sentry error tracking and performance monitoring
- Unit and integration tests with 80%+ coverage
- API documentation via Swagger or Postman
- Deployment scripts for AWS or your own server
- Admin panel with user management and audit logs
- Uptime monitoring with PagerDuty alerts
- One-year warranty on critical bugs
