What makes IRPR the best custom SaaS development service
We ship production-ready SaaS platforms that scale from day one.
IRPR has delivered 200+ SaaS products to clients in 50+ countries. Our average MVP ships in 12 weeks, and 98% of projects deliver on time. Every platform hits 99.9% uptime using AWS multi-region deployment.
We use a fixed-price model starting with a Roadmap phase. In week 2 you get a detailed scope document with wireframes, API contracts, and a fixed quote. No hourly billing, no surprises.
Generic dev shop vs IRPR: the real difference
Most development agencies bill hourly and hand off incomplete code. IRPR does the opposite.
Generic shops often start building without a clear plan, then bill you for every meeting and revision. They rarely deliver compliance, CI/CD, or infrastructure documentation.
IRPR builds your SaaS on a fixed price after a 3-week Roadmap phase. You get full code ownership, automated deployments, and compliance certification from day one.
- Hourly billing that rewards slow work
- No compliance experience (HIPAA, PCI, SOC 2)
- Hands you code with no CI/CD or monitoring
- Junior developers learning on your dime
- Unclear scope that changes mid-project
- You pay for ongoing server management separately
- Fixed price agreed in week 2
- HIPAA, PCI-DSS, SOC 2 built into every project
- GitHub Actions CI/CD + Sentry error tracking from day one
- Senior engineers only, average 10+ years experience
- Exact scope locked after Roadmap phase
- Infrastructure code (Terraform) included -- no surprises
How we build your custom SaaS in 12 weeks
Our process has four phases: Idea, Roadmap, Product, Release.
We start with a 1-week Idea call where we align on target users, core features, and revenue model. Then we move to a 2-week Roadmap phase that produces wireframes, API design, and a fixed price.
The Product phase runs 8-10 weeks of senior engineer development. We build your SaaS in 2-week sprints with daily standups and a production demo every sprint. The Release phase deploys to AWS with monitoring and documentation.
What ships with your custom SaaS
You don't just get a codebase. You get a production-ready platform.
Every SaaS delivery includes source code in your repo, CI/CD pipeline, error tracking, and infrastructure-as-code. You can deploy independently on day one.
IRPR also provides a runbook for your ops team and a 30-day warranty for any bugs found post-release.
- Source code in your GitHub repository
- CI/CD pipeline on GitHub Actions with automated testing
- Sentry error tracking with alerting
- AWS infrastructure via Terraform (not manual console)
- PostgreSQL database with automated backups
- Stripe integration for subscription billing (if applicable)
- Auth0 or Clerk for user authentication
- Postman collection for API testing
- Runbook with login credentials and deploy instructions
- 30-day bug fix warranty
