Generic Dev Shop vs IRPR: React.js Consulting
Not all React consultants deliver the same quality.
Most agencies write vague SOWs and charge by the hour. Scope creep leads to budget overruns and missed deadlines.
IRPR writes a fixed-fee contract after a 2-week Roadmap phase. You know the exact price and timeline before we build anything.
- Hourly billing that rewards slow work
- Unclear deliverables and shifting scope
- Junior developers on your project
- No dedicated project manager
- Code ownership often contested
- Long discovery phases with no fixed timeline
- Fixed price contract from week 2
- Detailed roadmap with clear milestones
- Senior engineers only (7+ years experience)
- US-based project manager weekly check-ins
- Full source code ownership from day one
- 12-week average delivery time
