Why hire experienced B2B SaaS development consultants
Building a SaaS product requires more than code. It requires architecture decisions that scale from 10 to 10,000 users.
IRPR has shipped over 200 SaaS products across 50 countries. Our consultants have built multi-tenant systems that handle 100,000+ requests per day on a single AWS instance. We use tools like Terraform for infrastructure, Docker for containerization, and GitHub Actions for CI/CD.
Every project starts with a 2-week Roadmap phase where we define the database schema, API endpoints, and user flows. You get a fixed price quote before any development starts. No surprises, no scope creep.
The difference between a generic dev shop and IRPR
Most agencies bill hourly and change scope mid-project. IRPR works differently.
Generic dev shops often start coding without a clear roadmap. They bill by the hour, so every revision costs more. They rarely understand SaaS architecture patterns like multi-tenancy, tenant isolation, or subscription billing.
IRPR is built by senior engineers who have launched SaaS products themselves. We follow the Idea - Roadmap - Product - Release framework. You get a fixed price, a clear timeline, and a product that scales.
- Hourly billing with no cap
- No SaaS-specific architecture experience
- Scope changes without written change orders
- No compliance knowledge (HIPAA, SOC 2)
- Code ownership not clearly defined
- No post-launch support plan
- Fixed price from the Roadmap phase
- 200+ SaaS products shipped across 50 countries
- Written scope with a 2-week Roadmap phase
- Built-in compliance for HIPAA, PCI-DSS, SOC 2
- Full source code ownership in your repo
- 12-week support and maintenance included
Our 4-phase process for building your B2B SaaS
We break every project into four phases so there are no surprises.
Phase 1 is the Idea phase where we align on your product vision and target market. Phase 2 is the Roadmap phase where we produce a detailed technical specification and a fixed price quote.
Phase 3 is the Product phase where we build the MVP in 8-12 weeks using agile sprints. Phase 4 is the Release phase where we deploy to production, set up monitoring with Sentry and Datadog, and hand over full documentation.
What ships with your B2B SaaS product
Every project includes these deliverables by default.
You own everything we build. No licensing fees, no recurring royalties. We set up your development environment so your team can continue after launch.
All code is stored in your private GitHub repository. We configure CI/CD pipelines with GitHub Actions and deploy to AWS or GCP. You get access to error tracking with Sentry and performance monitoring with Datadog.
- Source code in your private GitHub repo
- CI/CD pipeline using GitHub Actions

- API documentation via Swagger or Postman
- Sentry error tracking configured
- Datadog performance monitoring
