Why choose IRPR as your custom SaaS development vendor
We are not a generic dev shop. We are a senior-only team that delivers on time and on budget.
Every custom SaaS development vendor promises quality. IRPR delivers it with a fixed price, a clear timeline, and full code ownership. Our 200+ products include multi-tenant platforms, subscription apps, and compliance-heavy systems for healthcare and fintech.
We use the same tools as top SaaS companies: React, Node.js, PostgreSQL, AWS, Stripe, Sentry, Datadog. Every project ships with a CI/CD pipeline, automated tests, and monitoring. You get a product that can scale from day one.
How IRPR differs from other SaaS development vendors
Most agencies charge by the hour and never finish. IRPR gives you a fixed price and a shipping date.
We have seen hundreds of contracts where a custom SaaS development vendor starts strong and then disappears. IRPR works the opposite way. We give you a fixed quote after a 2-week Roadmap phase. No surprises.
Our engineers are all senior. No juniors. No subcontractors. That means your code is clean, documented, and ready for production. We also handle compliance (SOC 2, HIPAA, PCI-DSS) so you don't have to.
- Vague timelines and scope creep
- Hourly billing with no cap
- Junior developers learning on your dime
- No compliance knowledge
- Code delivered without tests or CI/CD
- No post-launch support
- Fixed price after Roadmap phase (week 2)
- 8-12 week MVP delivery
- Senior engineers only (10+ years average)
- Built-in SOC 2, HIPAA, PCI-DSS readiness
- Full CI/CD pipeline with GitHub Actions and Sentry
- Post-launch monitoring and 99.9% uptime guarantee
Our process for building custom SaaS products
We turn your idea into a live product in 8-12 weeks with no hidden steps.
IRPR follows a four-phase process: Discovery, Roadmap, Build, Release. Each phase has clear deliverables and milestones. You see progress every sprint.
We use agile with two-week sprints. Every sprint ends with a demo. You can test the product, give feedback, and adjust priorities. This keeps the project on track and under budget.
What ships with every custom SaaS project
You get more than code. You get a production-ready system with all the tooling.
Every project from IRPR includes a full DevOps setup, monitoring, and documentation. We do not hand over a zip file and disappear. Your team can take over immediately.
We also include a 30-day post-launch support period. If anything breaks, we fix it same day. After that, you can extend support monthly or go self-sufficient.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Sentry error tracking and performance monitoring
- AWS infrastructure as code (Terraform)
- Admin panel for user and subscription management
- API documentation via Swagger/OpenAPI
- Database schema with migrations
- Deployment scripts and runbooks
- Load testing report (k6)
- Post-launch support for 30 days
