Why expert B2B SaaS development matters
Building a B2B SaaS product is different from consumer apps. It needs multi-tenancy, SSO, billing, and compliance from day one.
A generic web development shop often skips these requirements until after launch. That leads to costly rewrites and security gaps when you need to scale. IRPR builds them into your architecture from the start.
Our process includes every B2B SaaS must-have: tenant isolation, usage analytics, role-based access, and payment integration. You get production-ready code that passes SOC 2 audits without retrofitting.
How we differ from other agencies
Most development shops hide costs and assign junior developers. IRPR is built differently.
We quote a fixed price in the Roadmap phase (week 2) and only use senior engineers with 7+ years of experience. Every project has a dedicated tech lead who writes code and reviews every PR.
You get full documentation, CI/CD pipelines, and error monitoring included. There are no surprise budgets or handoff gaps.
- Hourly billing with no cap
- Junior and mid-level devs only
- No compliance knowledge
- Missed deadlines common
- No documentation provided
- Code stays with them
- Fixed price from day one
- Senior engineers only (7+ years)
- SOC 2 and PCI compliant by design
- 98% on-time delivery record
- Full architecture docs included
- You own all source code and IP
Our process for expert B2B SaaS development
We follow a four-phase process that gets your product to market fast without cutting corners.
Each phase has a clear deliverable and a go/no-go decision point. You always know what comes next and exactly how much it costs.
Our process works for startups needing a quick MVP and for enterprises building internal tools. We adapt the timeline based on your complexity.
What ships with every B2B SaaS project
Every deliverable includes essential production infrastructure so you can launch immediately.
We don't hand over raw code. You get a fully deployed application with automated testing, monitoring, and documentation.
All assets are in your GitHub repo from the first commit. There are no access restrictions or licensing fees.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions or CircleCI
- Staging and production environments on AWS or GCP
- Sentry error tracking and performance monitoring
- Automated test suite (unit, integration, E2E)
- API documentation via Swagger or Postman
- Admin dashboard with user management and logs
- Deployment runbook and architecture diagram
- 30 days of post-launch bug fixes and support
- Full ownership of all intellectual property
