The difference between IRPR and generic dev shops
Not all custom application consultants deliver the same results.
Generic shops often bill hourly, use junior devs, and leave you without ownership. That leads to budget overruns and broken code.
IRPR gives you fixed pricing, senior engineers, and full code ownership. Our 4-phase process ensures your project is on time and on budget.
- Hourly billing with no cap
- No fixed timeline
- Junior developers with little oversight
- No compliance expertise (HIPAA, PCI, SOC 2)
- Code often not handed over cleanly
- Slow communication and missed deadlines
- Fixed price after Roadmap phase (week 2)
- 8-12 week delivery for MVPs
- Senior engineers only (10+ years experience)
- Built-in HIPAA, PCI-DSS, SOC 2 compliance
- Full source code ownership from day one
- Weekly updates and Slack-based communication
