How IRPR Compares to Other Vendors
Most B2B web app vendors overpromise and underdeliver. IRPR is different.
Generic dev shops often use junior developers, charge hourly, and miss deadlines. They don't understand B2B workflows like multi-tenancy, role-based access, or compliance requirements.
IRPR assigns senior engineers only. We give you a fixed price after the Roadmap phase. We ship in 8-12 weeks. And we own the code quality with automated testing, CI/CD, and security reviews.
- Junior developers with limited B2B experience
- Hourly billing with no cap
- No compliance expertise (HIPAA, PCI-DSS, SOC 2)
- Unclear timelines and scope creep
- No post-launch support plan
- Code ownership often disputed
- Senior engineers only, average 10+ years experience
- Fixed price after 2-week Roadmap phase
- Built-in compliance for healthcare, fintech, and SaaS
- 8-12 week delivery with weekly demos
- Post-launch support with 99.9% uptime SLA
- Full code ownership transferred to you
Our B2B Web App Development Process
We follow a 4-phase process that guarantees clarity, speed, and quality.
Every project starts with a 2-week Roadmap phase where we define the architecture, tech stack, and fixed price. You get a detailed plan before any development begins.
Then we build your MVP in 8-12 weeks with weekly demos and a dedicated project manager. After launch, we provide 30 days of support and a 99.9% uptime SLA.
What Ships with Every B2B Web App
Every project includes these deliverables by default. No hidden costs.
We don't just hand over code. You get a fully documented, production-ready web app with everything needed to run and scale.
Our standard package includes source code, CI/CD pipeline, monitoring, and compliance documentation. You own everything.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions or GitLab CI
- Sentry error tracking and monitoring
- Automated test suite (unit, integration, e2e)
- Deployment to AWS, GCP, or Azure
- PostgreSQL database with migrations
