Why we are the best custom SaaS development agency
We have the data to back it up.
IRPR has shipped over 200 SaaS products across 50 countries. Our 8 to 12 week delivery timeline beats the industry average by 40%.
Every project is built by senior engineers with 10+ years of experience. We maintain a 98% on-time delivery rate and 99.9% uptime across all deployments.
How we differ from generic agencies
Not all SaaS development is the same.
Generic dev shops often overpromise and underdeliver. They use junior developers and charge by the hour with no fixed end date.
IRPR takes a different approach. We give you a fixed price and a fixed timeline from week 2. Every line of code is written by a senior engineer.
- Vague estimates and hourly billing
- Junior developers on your project
- No compliance guarantees (HIPAA/PCI)
- 6+ month delivery timelines
- No code ownership until final payment
- No built-in CI/CD or monitoring
- Fixed price after week 2 roadmap
- Senior engineers only (10+ years experience)
- HIPAA, PCI-DSS, SOC 2 out of the box
- 8-12 week MVP delivery
- Full code ownership from day one
- CI/CD pipeline and Sentry monitoring included
Our SaaS development process
We follow a proven 4-phase approach.
Each phase has clear deliverables and gates. You stay in control without micromanaging.
From idea to production, we complete the entire cycle in under 12 weeks.
What ships with every SaaS platform
These deliverables are standard.
Every IRPR project includes the following as part of the fixed price. No hidden fees or add-ons.
- Source code in your private GitHub repo
- CI/CD pipeline with automated tests on GitHub Actions
- Stripe or Paddle billing integration
- Admin dashboard with usage analytics
- Sentry error monitoring and alerting
- Deployed on AWS or GCP with 99.9% uptime SLA
- User authentication and role-based access control
- API documentation (OpenAPI/Swagger)
- 30-day post-launch support and bug fixes
