How IRPR differs from other B2B SaaS website development vendors
Most agencies bill hourly and hand off junior developers. IRPR gives you senior engineers and a fixed price.
Generic dev shops often assign junior developers who learn on your dime. They bill hourly, so scope creep costs you more. They rarely handle compliance or CI/CD. You end up with a site that breaks on mobile and takes 6 months to launch.
IRPR assigns senior engineers only. We give you a fixed price in week 2. We build with Next.js, handle SOC 2 and PCI-DSS compliance, and ship a CI/CD pipeline. Your site launches in 8-12 weeks, not 6 months.
- Junior developers with 1-2 years experience
- Hourly billing with no cap
- No compliance expertise (SOC 2, HIPAA, PCI-DSS)

Our process for building the best B2B SaaS website
We follow a 4-phase process that guarantees on-time delivery and a site that converts.
Phase 1 is the Idea phase where we align on goals, target audience, and key features. Phase 2 is the Roadmap phase where we define the tech stack, compliance needs, and fixed price. Phase 3 is the Product phase where we build the site in 8-12 weeks. Phase 4 is the Release phase where we deploy and monitor.
Each phase has clear deliverables and milestones. You get weekly demos and a Slack channel with the team. No surprises, no scope creep.
