Why choose the best SaaS platform development firm
Not every dev shop can deliver a compliant, scalable SaaS platform on time and on budget.
IRPR has built over 200 SaaS products across 50+ countries. Our senior engineers average 12+ years of experience. Every project ships with a 99.9% uptime SLA and full end-to-end testing.
We use a fixed-price model with a 2-week Roadmap phase. This de-risks your investment: you know the cost and timeline before a single line of production code is written. No hourly billing surprises.
How IRPR is different from generic developers
Most agencies bill by the hour and hand off incomplete code. We do the opposite.
Generic dev shops promise "full stack" but deliver a mess of undocumented code. They charge for every meeting and change request. After launch, you are left with no support.
IRPR takes responsibility for the entire lifecycle. We provide compliant architecture, automated CI/CD, error monitoring, and 3 months of post-launch support. Your team gets a production-ready system with 100% code ownership.
- Hourly billing that blows budgets
- Architecture that does not scale
- No compliance review (HIPAA/SOC 2)
- Code delivered once, no post-launch support
- Junior developers with minimal oversight
- No uptime guarantee
- Fixed price from Roadmap phase ($8K upfront)
- Multi-tenant architecture designed for 100K+ users
- Built-in compliance for HIPAA, SOC 2, PCI-DSS
- 3 months of full support after launch
- Senior engineers only (12+ years avg.)
- 99.9% uptime SLA
Our SaaS development process
We deliver predictable results in four clear phases.
Every engagement starts with a 2-week Roadmap. You get a detailed spec, wireframes, and a fixed price before we write production code. This de-risks your investment and aligns expectations.
After the Roadmap, we build your MVP in 8-12 weeks. Then we release with full CI/CD, documentation, and a support handoff.
What ships with every SaaS platform
You get more than just code. Every deliverable includes production-grade infrastructure.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions or GitLab CI
- AWS or GCP infrastructure as code (Terraform)
- Stripe billing integration (if subscription-based)
- PostgreSQL or Aurora database with automated backups
- Sentry error tracking and Datadog monitoring
- Unit and integration test suite (90%+ coverage)
- Admin dashboard for managing users and billing
- API documentation (OpenAPI or Postman collection)
- 3 months of post-launch support and bug fixes

Fixed price, not hourly
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the total cost within $8K upfront.
Senior engineers only (12+ years avg.)
We do not offshore or hire juniors. Every engineer on your project has at least 12 years of experience. They have built SaaS platforms for companies like Microsoft and Amazon.
8-12 week MVP guarantee
From Roadmap approval to launch, your MVP ships in 8-12 weeks. If we are late, we refund 10% of the build fee. This guarantee is written into every contract.
Compliance-first architecture
We build HIPAA, SOC 2, and PCI-DSS controls into the architecture from day one. No retrofitting. Our compliance checklist is verified by a third-party auditor.
Post-release support included
After launch, we provide 3 months of full support: bug fixes, monitoring, and small enhancements. You do not need to hire a separate maintenance team.
99.9% uptime SLA
Every platform deployed on AWS or GCP includes a 99.9% uptime SLA. We set up alerts and auto-scaling. If uptime drops, you get service credits.
Idea → Roadmap → Product → Release.
