Generic Dev Shop vs IRPR: The B2B Web App Difference
Choosing the right B2B web app development company means the difference between a 6-month delay and a launch in 12 weeks.
Most dev shops operate with junior developers and hourly billing. They have no compliance experience and no fixed timelines.
IRPR works with senior engineers only. We give you a fixed price in week 2 during the Roadmap phase. We provide SOC 2, HIPAA, and PCI-DSS compliance on every project that needs it.
- Hourly billing surprises
- Junior developers on your project
- No compliance expertise
- Vague timelines
- No source code handover
- No post-launch support plan
- Fixed price quoted in week 2
- Senior engineers only (5+ years experience)
- SOC 2, HIPAA, PCI-DSS ready
- 12-week MVP timeline
- Full source code ownership
- 60-day post-launch warranty
How We Build Your B2B Web App In 12 Weeks
Our process moves from idea to deployed product in 4 phases.
We start with a 2-week Roadmap phase where we define scope, architecture, and price. You get a fixed quote before any development begins.
