Why choose IRPR as your B2B SaaS development partner
We deliver production-ready B2B SaaS platforms with measurable results.
IRPR has shipped over 200 B2B SaaS products across 50 countries. Our average timeline from kickoff to launch is 12 weeks. We maintain a 98% on-time delivery rate and 99.9% platform uptime after launch.
Every project includes a fixed price, full code ownership, and compliance readiness for SOC 2, HIPAA, or PCI-DSS. Our team of senior engineers works in US timezone overlap hours, so communication is seamless.
How IRPR differs from other B2B SaaS development agencies
Most agencies bill hourly and delay projects. We do the opposite.
Generic development shops often start without a clear scope, leading to cost overruns and missed deadlines. They may not have experience with multi-tenant architectures or compliance requirements.
IRPR begins every engagement with a 2-week Roadmap phase where we define the full scope, tech stack, and fixed price. You know exactly what you're paying and when you'll launch.
- Hourly billing with no budget cap
- Unclear timeline estimates
- No compliance expertise
- Code ownership often disputed
- Limited experience with B2B SaaS
- Slow communication across time zones
- Fixed price from $80K to $250K
- 12-14 week delivery guarantee
- Built-in SOC 2, HIPAA, PCI-DSS readiness
- Full code ownership from day one
- 200+ B2B SaaS products shipped
- US timezone overlap hours daily
Our B2B SaaS development process in 4 phases
We break every project into clear, predictable phases.
Our process ensures you see progress every two weeks. Each phase ends with a demo and a go/no-go checkpoint.
From idea to production, we follow the same framework that has delivered 200+ successful products.
