Why choose IRPR as your expert custom SaaS development studio
We ship production-grade SaaS platforms faster and with higher quality than typical agencies.
Since 2016, IRPR has shipped over 200 SaaS products across 50 countries. Our senior engineers have built multi-tenant architecture, subscription billing, and admin portals for startups and enterprises alike. Every project goes through a structured Roadmap phase where we define scope, tech stack, and timeline in writing.
We use fixed pricing and bill in three milestones: Roadmap (week 2), Build (week 8), and Release (week 12). Our 98% on-time delivery rate comes from this process. No change orders, no surprise invoices. You get the code in your own GitHub repo from day one.
How IRPR differs from other custom SaaS development studios
Most agencies bill hourly and change scope. We do the opposite.
When you hire a generic dev shop, you get junior developers, hourly billing, and unclear timelines. The project usually goes over budget and the code quality is low. Many founders end up rewriting the entire product within six months.
IRPR assigns senior engineers only (average 10+ years of experience). We flat-fee price after the Roadmap phase. Every project ships with automated testing, CI/CD, error monitoring (Sentry), and full documentation. We also offboard the code to your team or manage it post-launch.
- Junior or offshore developers
- Hourly billing with creep
- No formal Roadmap phase
- Code ownership uncertain
- No CI/CD or testing
- Slow communication via email
- Senior engineers only (10+ yr avg)
- Fixed price after Roadmap
- Structured 2-week Roadmap
- Full code ownership from start
- CI/CD, Sentry, automated tests
- Daily Slack updates from your squad
Our SaaS development process from idea to release
Every project follows four clear phases to eliminate risk and keep delivery on track.
The process begins with a 2-week Roadmap where we define your product's scope, architecture, and tech stack. You get a detailed document with wireframes, database schema, API design, and a fixed price quote.
After signing off, the Build phase runs for 6-8 weeks. Each week you see a deployed version of the product with new features. We use continuous deployment so you can test in real time. The Release phase includes load testing, security audit (OWASP Top 10), and final launch.
What ships with every custom SaaS project from IRPR
Every project delivers a production-ready product with everything needed to operate.
We don't just hand over code. You get the entire operational stack: source code in your GitHub repo, automated deployments via GitHub Actions, error tracking with Sentry, application monitoring with Datadog, and a detailed onboarding guide.
For multi-tenant SaaS, we include tenant provisioning, user authentication (Auth0 or next-auth), subscription management with Stripe, and an admin dashboard. All code is tested with Jest and Cypress.
- Full source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions and Docker
- Stripe subscription billing integration
- Auth0 authentication (social, SSO, 2FA)
- Sentry error tracking and monitoring
- Datadog APM and uptime monitoring
- PostgreSQL database with migrations and backups
- Admin dashboard for tenant management
- API documentation (Swagger/OpenAPI)
- Load testing results (k6, JMeter)
