Why choose an affordable B2B SaaS website development partner
IRPR delivers production-ready SaaS websites at a fixed price with no hidden costs.
Most agencies charge by the hour and inflate timelines. IRPR gives you a fixed quote after a 2-week Roadmap phase. You know the exact cost and delivery date before we write a line of code. Our average MVP ships in 10 weeks, not 6 months.
We use a proven stack: Next.js for the frontend, Node.js for APIs, PostgreSQL for data, and AWS for hosting. Every project includes CI/CD via GitHub Actions, Sentry error tracking, and a 99.9% uptime SLA. You own the code from day one.
How IRPR compares to other development partners
Not all agencies deliver the same quality. Here is the difference.
Generic dev shops often use junior developers, change scope mid-project, and charge for every email. IRPR assigns senior engineers only, locks scope after the Roadmap, and includes project management in the fixed price.
We also handle compliance from the start. If you need SOC 2, HIPAA, or PCI-DSS, we build it into the architecture. No retrofitting. No surprise costs.
- Hourly billing with no cap
- Junior developers on your project
- Scope creep without change orders
- No compliance expertise
- No CI/CD or monitoring setup
- Code ownership unclear
- Fixed price from $80K
- Senior engineers only (8+ years)
- Scope locked after Roadmap phase
- Built-in SOC 2, HIPAA, PCI-DSS
- CI/CD, Sentry, 99.9% uptime SLA
- Full source code ownership
Our process for building your B2B SaaS website
We follow a 4-phase process that keeps your project on time and on budget.
Phase 1 is the Idea phase where we align on goals and user stories. Phase 2 is the Roadmap where we produce a detailed spec, wireframes, and a fixed quote. This takes 2 weeks and costs $5K, credited to the build.
Phase 3 is the Product build: 8-12 weeks of development with weekly demos. Phase 4 is Release: deployment to production, monitoring setup, and a 30-day warranty. You get a working SaaS platform, not a prototype.
What ships with every B2B SaaS website
Every project includes these deliverables by default. No add-ons, no upsells.
You get a production-ready SaaS platform with authentication, billing, and multi-tenant data isolation. We also include developer handoff documentation and a 30-day warranty for any bugs.
Our standard stack is Next.js, Node.js, PostgreSQL, and AWS. If you need a different stack, we can adjust during the Roadmap phase.
- Source code in your GitHub repo
- CI/CD pipeline on GitHub Actions
- Sentry error tracking
- Stripe billing integration
- Auth0 or Clerk authentication
- PostgreSQL database with migrations
- 99.9% uptime SLA
- 30-day post-launch warranty
- Technical documentation and runbook
- Admin dashboard with user management
