What you get with an expert B2B web app development vendor
IRPR delivers a complete production-ready B2B web app, not just code.
Every project starts with a two-week Roadmap phase where we define scope, tech stack, and fixed price. We build with senior developers only, no juniors. Your app ships with automated testing, CI/CD, and 99.9% uptime infrastructure.
We have shipped over 200 products for clients in 50+ countries. Our track record includes 98% on-time delivery and full compliance with SOC 2, HIPAA, and PCI-DSS standards.
Generic dev shop vs IRPR - the difference matters
Most agencies bill hourly and hand off messy code. IRPR gives you a fixed price and a shippable product.
A generic dev shop often hires junior talent, changes scope, and charges extra for compliance. You end up with code you don't own and no post-launch support.
IRPR assigns senior engineers only, provides a fixed price after the Roadmap, and guarantees full IP ownership. We handle SOC 2, HIPAA, and PCI-DSS from day one.
- Hourly billing with no cap
- Junior developers on your project
- Unpredictable timelines
- No compliance expertise
- Code ownership unclear
- No post-launch support
- Fixed price after Roadmap
- Senior engineers only (10+ years)
- 8-12 week delivery
- SOC 2, HIPAA, PCI-DSS built in
- Full code ownership
- 30-day post-launch support
