Why IRPR Is a Top Custom SaaS Development Agency
We have shipped over 200 SaaS products across 50 countries with a 98% on-time delivery rate.
Our team of senior engineers averages 8+ years of experience each. We use a fixed-price model that starts with a 2-week Roadmap phase. That Roadmap costs $8K and produces a detailed spec, wireframes, and a fixed quote for the full build.
We support SOC 2 Type II, HIPAA, and PCI-DSS compliance out of the box. Our clients include funded startups in New York, enterprise teams in Chicago, and SaaS companies in Los Angeles.
How We Differ From Other SaaS Development Agencies
Most agencies bill hourly and change scope mid-project. IRPR does the opposite.
We give you a fixed price after a 2-week Roadmap. That price does not change unless you add major features. We use weekly sprint reviews and a shared Slack channel so you see progress in real time.
Every project includes automated testing, CI/CD with GitHub Actions, and error tracking with Sentry. We deploy to AWS ECS or DigitalOcean. You get production-ready infrastructure from week one.
- Hourly billing with no cap
- Junior developers on your project
- No compliance documentation
- You own nothing until final payment
- No CI/CD or monitoring setup
- Scope creep leads to budget overruns
- Fixed price after Roadmap phase
- Senior engineers only (8+ years avg)
- SOC 2 / HIPAA / PCI-DSS ready
- Full source code ownership from day one
- CI/CD pipeline and Sentry included
- Scope locked at Roadmap sign-off
Our Process for Building Custom SaaS Products
We follow a 4-phase process that de-risks your investment and delivers a production-ready platform.
Each phase has a clear deliverable and a fixed timeline. You approve the output before we move to the next phase. This keeps the project on schedule and on budget.
We use a shared Notion workspace and weekly video calls. You talk directly to the lead engineer, not a project manager.
What Ships When You Hire IRPR
Every project includes these deliverables by default. No add-ons, no hidden fees.
We believe in full transparency. You get everything you need to run, maintain, and scale your SaaS product. There is no vendor lock-in.
All code is written to production standards. We follow SOLID principles and include unit tests with Jest and integration tests with Cypress.
- Source code in your GitHub repo
- CI/CD pipeline on GitHub Actions
- Sentry error tracking and monitoring
- Stripe billing integration with webhooks
- Auth0 or Clerk user authentication
- AWS ECS or DigitalOcean deployment
- Database schema and migration scripts
- Admin dashboard with analytics
- API documentation (Swagger or GraphQL)
- One-year warranty on code defects
