Why hire a senior custom SaaS development company
Building SaaS requires more than just code. It needs architecture that scales, billing that works, and compliance that passes audits.
IRPR has shipped over 200 SaaS products across 50 countries. Every platform we build starts with a multi-tenant architecture, a payment integration, and a CI/CD pipeline. We use React, Next.js, Node.js, PostgreSQL, and deploy on AWS or GCP.
Our senior engineers average 12+ years of experience. We do not use junior developers. Every line of code is reviewed, tested, and documented. You own everything from day one.
The difference between IRPR and a generic dev shop
Most agencies promise senior talent but deliver junior work. IRPR is a senior custom SaaS development company that holds itself to a different standard.
Generic dev shops often use hourly billing, change requirements without notice, and hand over code with no documentation. They rarely understand multi-tenancy, billing systems, or compliance requirements.
IRPR works on fixed price contracts defined in the Roadmap phase. We ship every project with automated tests, CI/CD, monitoring, and a runbook. Our engineers own the outcomes, not just the output.
- Hourly billing with no cap
- Junior developers on your project
- No multi-tenant architecture
- No CI/CD pipeline
- No documentation or tests
- You do not own the source code
- Fixed price from the Roadmap phase
- Senior engineers with 12+ years experience
- Multi-tenant architecture built in
- CI/CD pipeline on GitHub Actions
- Automated tests and runbook included
- Full source code ownership
How we build your SaaS platform in 12 weeks
Our process is designed to eliminate surprises. Every phase has a clear deliverable and a fixed timeline.
We start with a 2-day workshop to define the product scope, user flows, and technical architecture. Then we move into 2-week sprints with demos every Friday. By week 8, you have a working MVP.
The final 4 weeks focus on hardening: security reviews, load testing, compliance audits, and deployment to production. You get a platform that is ready for real users.
What ships with every SaaS platform
When you work with a senior custom SaaS development company, you do not just get code. You get a complete product that is ready to run.
Every project includes auth, billing, a responsive UI, and a deployment pipeline. We also add monitoring, error tracking, and analytics so you can see how users behave from day one.
You own everything. There is no ongoing license fee, no revenue share, no hidden costs. IRPR hands over the keys and you drive.
- Source code in your GitHub repository
- CI/CD pipeline on GitHub Actions
- Stripe billing integration with subscription plans
- Auth0 or Clerk authentication
- Sentry error tracking and performance monitoring
- PostgreSQL database with automated backups
