Generic Dev Shop vs Senior B2B SaaS Website Development Vendor
Most agencies promise quality but deliver junior work. IRPR is different.
Generic shops often assign junior developers who learn on your project. They use hourly billing that rewards slow work. Code quality suffers and timelines slip.
IRPR assigns senior engineers only. We fix the price in week 2 during the Roadmap phase. You get full code ownership and a CI/CD pipeline that deploys automatically.
- Junior developers with 1-3 years experience
- Hourly billing with no cap
- No dedicated QA engineer
- Code delivered without tests

- Vague timeline estimates
- Senior engineers with 10+ years experience
- Fixed price from Roadmap phase
