Why Hire a Professional B2B SaaS Development Vendor
Building a SaaS platform is complex. IRPR removes the risk with a proven process and fixed pricing.
We have delivered 200+ SaaS products across 50 countries. Our senior engineers average 10+ years of experience. Every project uses modern tooling like Next.js, Node.js, PostgreSQL, and AWS.
We focus on B2B platforms that need compliance, multi-tenancy, and billing. Our fixed-price model means no surprises. You know the cost and timeline before we write code.
The Difference Between IRPR and Generic Agencies
Most agencies bill by the hour and disappear after launch. IRPR is different.
We are a professional B2B SaaS development vendor, not a body shop. Every developer is a senior engineer with at least 10 years of experience. We do not outsource or subcontract.
Our process starts with a Roadmap phase where we define scope and price. You get a fixed quote and a Gantt chart before any development begins.
- Hourly billing with no cap
- Uses junior developers
- No compliance expertise
- Delivers buggy code
- No post-launch support
- Unclear code ownership
- Fixed price from Roadmap
- Senior engineers only (10+ years)
- Built-in SOC 2 from day 1
- CI/CD and automated testing
- Full production support SLA
- You own all source code
Our SaaS Development Process
We follow a four-phase process that de-risks your build and delivers on time.
Every engagement starts with a free discovery call. Within 2 weeks we deliver a detailed Roadmap with architecture, database schema, API contracts, and a fixed price.
Development runs in 2-week sprints. You see working software every Friday. We deploy to staging and you test before production launch.
What Ships With Every SaaS Project
You get more than just code. Every project includes production-grade infrastructure and documentation.
- Source code in your GitHub repo
- CI/CD pipeline on GitHub Actions
- Sentry error tracking
- Datadog performance monitoring
- Staging and production environments
- API documentation (Swagger)
- Automated test suite (unit + integration)
- Admin dashboard with user management
- Billing integration (Stripe or Recurly)
- SOC 2 compliance documentation pack

Why teams hire us.
Fixed Price, Not Hourly
Every project gets a fixed quote during the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the exact cost before we write code.
Senior Engineers Only
Our team consists of engineers with 10+ years of experience each. No junior developers or interns. We have shipped 200+ products across 50 countries.
8-12 Week MVPs
We deliver production-ready MVPs in 8-12 weeks. Our record is 6 weeks for a subscription billing platform. That speed comes from proven templates and CI/CD automation.
SOC 2 Built In
We treat security as a feature, not an afterthought. Our architecture includes encryption, audit logs, and access controls. 98% of our clients pass SOC 2 audit within 3 months of launch.
Full Code Ownership
You own all source code, documentation, and IP from day one. No licensing fees, no ongoing royalties. We transfer everything to your GitHub account at the end of the project.
Post-Launch Support
We offer 30 days of free warranty and then optional support at $4,000/month. That includes hotfixes, monitoring, and minor feature work. 85% of clients continue with support after launch.
Idea → Roadmap → Product → Release.
