The difference between IRPR and other B2B SaaS website development vendors
Most vendors bill hourly and change scope. We do the opposite.
Generic development shops often start with a vague estimate and bill by the hour. Scope creep is common. You never know the final cost until the project is done. Communication is slow. Code quality is inconsistent.
IRPR gives you a fixed price after a 2-week Roadmap. We use the same senior engineers from start to finish. You get daily updates in Slack. Code is in your repo from day one. No surprises.
- Hourly billing with no cap
- Junior developers on your project
- Scope creep without price adjustment
- No compliance expertise
- Code stays on their servers
- Slow email-only communication
- Fixed price after 2-week Roadmap
- Senior engineers only (10+ years)
- Scope locked in Roadmap phase
- HIPAA, PCI-DSS, SOC 2 ready
- Source code in your repo from day one
- Daily Slack updates
How IRPR builds your B2B SaaS website
