Why choose IRPR as your B2B SaaS development vendor
We deliver production-ready B2B SaaS products on time and on budget.
IRPR has shipped over 200 B2B SaaS products across 50 countries. Our average MVP timeline is 10 weeks. We use a fixed price model so you know the cost before we write a line of code.
Every B2B SaaS project includes multi-tenant architecture, Stripe billing integration, and SOC 2 compliant infrastructure. We deploy to AWS with auto-scaling and 99.9% uptime SLA.
The difference between a generic dev shop and IRPR
Not all B2B SaaS development vendors deliver the same results.
Generic dev shops often build single-tenant apps with no billing integration. They charge hourly and scope creep kills your budget.
IRPR builds multi-tenant SaaS platforms with Stripe, Auth0, and Datadog out of the box. You get a fixed price and a clear timeline.
- Hourly billing with no cap
- Single-tenant architecture
- No billing or auth integration
- No monitoring or logging
- No compliance documentation
- Code ownership unclear
- Fixed price from Roadmap phase
- Multi-tenant by default
- Stripe, Auth0, SendGrid integrated
- Datadog monitoring and Sentry errors
- SOC 2 evidence ready
- Full code ownership
Our B2B SaaS development process
We move from idea to production in four phases.
Phase 1 is a 2-week Roadmap where we define architecture, user flows, and a fixed price. Phase 2 is a 8-12 week MVP build using Next.js, Node.js, and PostgreSQL.
Phase 3 is the release to production with CI/CD, monitoring, and compliance checks. Phase 4 is ongoing support with a 99.9% uptime SLA.
