What Makes an Expert B2B SaaS Development Company
Not every agency can ship a multi-tenant platform with compliance, billing, and 99.9% uptime in 12 weeks.
IRPR has built 200+ SaaS products across 50+ countries. Every project uses battle-tested architectures: Next.js for frontend, Django or Node.js for backend, PostgreSQL for data, and Stripe for billing. We add Redis for caching, Sentry for error tracking, and Datadog for monitoring.
Our teams are 100% senior engineers. No juniors. No outsourcing. Every developer has 8+ years of experience. We work async-first with 4-hour overlap with US time zones. You talk to the same people who write the code.
How IRPR Differs from Generic Dev Shops
Most agencies bill hourly, use junior talent, and deliver incomplete code. We do the opposite.
IRPR charges a fixed price based on a detailed Roadmap (week 1-2). You pay a single fee and get the full scope. No hourly rates, no time tracking, no surprise invoices. If the scope changes, we adjust the price upfront.
We ship fully tested, documented code with CI/CD, automated tests, and monitoring. Every project includes a private GitHub repo, a staging environment on AWS, and a handoff session. You own everything from day one.
- Hourly billing with no price cap
- Junior developers assigned to your project
- No compliance expertise (HIPAA, SOC 2, PCI)
- Code delivered without tests or documentation
- No post-launch monitoring or error tracking
- Vague timelines that slip by weeks
- Fixed price locked from the Roadmap phase
- 100% senior engineers with 8+ years experience
- Built-in compliance modules for HIPAA, SOC 2, PCI
- Full test suite (unit, integration, E2E) and CI/CD
- Sentry error tracking and Datadog monitoring included
- 8-12 week timeline with 98% on-time record
Our B2B SaaS Development Process
We follow a four-phase process that de-risks your investment from day one.
Phase 1 (Roadmap) takes 1-2 weeks. We analyze your idea, competitor SaaS platforms, and technical requirements. You get a detailed spec, wireframes, architecture diagram, and a fixed price quote.
Phases 2-4 cover development, QA, and release. We build in 2-week sprints with demos every Friday. You see working software every iteration. After launch, we provide 30 days of support and a handoff guide.
What Ships with Every B2B SaaS Project
Every deliverable is production-ready and documented.
You don't get just code. You get a complete, deployable SaaS platform with all the infrastructure, monitoring, and documentation needed to run a business. Our standard delivery includes everything listed below.
- Source code in your GitHub repo (private, full commit history)
- CI/CD pipeline on GitHub Actions (test, build, deploy to AWS)
- Serverless or ECS infrastructure with auto-scaling
- Stripe subscription billing with free trial and coupon support
- Auth system with email OTP, Google/SSO (Auth0 or Supabase)
- Role-based access control (admin, user, viewer roles)
- Sentry error tracking and Datadog monitoring
- PostgreSQL database with automatic backups (daily, encrypted)
- Admin dashboard for user and subscription management
- API documentation (OpenAPI/Swagger) and Postman collection
