Why choose IRPR as your top B2B SaaS development agency
We deliver production-ready SaaS products in 12 weeks with a fixed price.
Every B2B SaaS project at IRPR begins with a 2-week Roadmap phase. We define the scope, tech stack, and integrations before writing a single line of code. This eliminates surprises and keeps the timeline predictable.
Our engineers have shipped over 200 products across 50 countries. We build for security and scale: SOC 2, HIPAA, and PCI-DSS are standard. You get full source code ownership and a CI/CD pipeline on GitHub Actions.
How we differ from other development agencies
Most agencies bill hourly and change scope mid-build. We don't.
Generic development agencies often start with a rough estimate and then add charges for every change. They use junior developers to keep costs low. Documentation is sparse, and the codebase is hard to maintain.
IRPR uses a fixed price model defined in the Roadmap phase. All engineers are senior level (7+ years experience). We deliver complete documentation, automated tests, and a production-ready infrastructure. No scope creep, no surprises.
- Hourly billing with no cap
- Junior developers on your project
- Scope changes every sprint
- No compliance experience
- Delays of 4-8 weeks
- No DevOps setup included
- Fixed price from week 2
- Senior engineers only
- Scope locked after Roadmap
- SOC 2 / HIPAA / PCI built-in
- 12-week delivery guarantee
- Infrastructure as code on AWS
Our process for building your B2B SaaS
Four phases, from idea to release.
We start with a 2-week Roadmap to define exactly what we'll build and how much it costs. Then we move to 8-10 weeks of development, followed by 2 weeks of testing and deployment. Post-launch support is available.
Every phase includes client demos, automated testing, and performance benchmarks. We use GitHub Projects for transparency and send weekly status updates.
What ships with every B2B SaaS project
More than just code.
Every project includes production infrastructure, monitoring, and documentation. You own everything. There are no recurring license fees or lock-in contracts.
We set up Stripe billing, user authentication, and email notifications as part of the base build. Integrations like HubSpot, Salesforce, and QuickBooks are included if in scope.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Automated unit and integration tests
- Production deployment on AWS or GCP
- Sentry error tracking and monitoring
- Stripe Billing setup with subscription logic
- Auth0 or Cognito user management
- PostgreSQL database with automated backups
- Swagger/OpenAPI documentation
- Admin dashboard with user management
