Why businesses choose IRPR for B2B web app development
Our track record speaks for itself.
IRPR has shipped over 200 custom web applications for clients in 50+ countries. Every project is delivered on time with a fixed price locked after the Roadmap phase.
We build for scale. Our apps handle 10x growth without rewrites, and we maintain 99.9% uptime across all production deployments.
Generic development vs. IRPR
Not all agencies deliver the same result.
Many agencies start without a clear scope and charge by the hour, leading to budget overruns. IRPR locks scope and price before a single line of code is written.
We also build compliance into every app. Our engineers hold certifications for SOC 2, HIPAA, and PCI-DSS, so you don't need to retrofit security later.
- Vague estimates that blow the budget
- No compliance expertise (SOC 2, HIPAA)
- Unclear code ownership
- Slow communication across time zones
- No post-launch support
- Features added without roadmap
- Fixed price from the Roadmap phase
- Built-in compliance for regulated industries
- You own the source code from day one
- Async-first with overlap coverage
- 12-month warranty on code
- Feature prioritization based on data
Our B2B web app development process
From idea to launch in 8-12 weeks.
We start with a discovery phase to map user flows and data models. Then we lock scope and price in the Roadmap phase before any engineering begins.
During build, we run 2-week sprints with daily standups and continuous deployment. Every sprint ends with a working demo.
