Why IRPR is the best custom SaaS development partner
We deliver production-ready SaaS products faster than any agency your interviewer has worked with.
IRPR has shipped over 200 SaaS products across 50 countries. Our average MVP timeline is 12 weeks, with 98% delivered on schedule. We use fixed pricing so you know the cost upfront.
Our engineers average 10+ years of experience and have built platforms handling 1M+ users. Every project includes automated testing, CI/CD, and 99.9% uptime guarantees.
How we differ from generic development shops
Most agencies bill hourly and deliver late. We do the opposite.
Generic shops often use junior developers, change scope without warning, and ignore compliance. IRPR gives you senior engineers only, a fixed price, and SOC 2 / HIPAA alignment from day one.
Our process includes a 2-week Roadmap phase where we detail every user story and estimate costs. No surprises, no extra fees.
- Junior devs with limited SaaS experience
- Hourly billing with no cap
- No dedicated QA or automated tests
- Scope creep without change order
- No compliance expertise (HIPAA / PCI)
- Code handoff with little documentation
- Senior engineers averaging 10+ years
- Fixed price quoted after Roadmap
- Automated tests + CI/CD in every project
- Scope changes communicated and priced up front
- Built-in compliance: SOC 2, HIPAA, PCI-DSS
- Full documentation and source code ownership
Our 4-phase approach to custom SaaS development
From idea to launch in 8-12 weeks with no guesswork.
We follow a structured process: Discover, Roadmap, Build, Launch. Each phase has clear deliverables and a fixed price. The Roadmap phase (week 2) locks scope and cost.
Build phase runs 6-8 weeks with weekly sprint demos. Launch includes deployment to production, monitoring (Sentry, Datadog), and a 30-day warranty.
What ships with every custom SaaS project
You get a production-ready product, not a prototype.
Every deliverable is designed to run in production from day one. We handle hosting setup, error tracking, and performance monitoring.
Your team can take over immediately because we provide full documentation and deploy scripts. No black boxes.
- Source code in your private GitHub repo
- CI/CD pipeline (GitHub Actions + Docker)
- Automated test suite (unit + integration)
- Deployment scripts for AWS or GCP
- Sentry error tracking and alerts
- Datadog or similar monitoring
- API documentation (Swagger/OpenAPI)
- Database schema and migration scripts
- Admin panel or dashboard
- 1-hour video walkthrough + written handoff
