Why choose a fixed-price B2B portal agency
Hourly billing leads to blowout budgets. IRPR delivers a fixed price from day one.
Most agencies charge by the hour. If they take longer, you pay more. We quote a fixed price after a 2-week Roadmap phase. That price does not change, even if we discover new requirements during development.
Our process covers discovery, design, build, and deploy. At the end of 8-12 weeks, you get a live B2B portal with full source code ownership. No ongoing license fees, no vendor lock-in.
IRPR vs generic development shops
Not all agencies deliver the same quality. Here is how we differ.
A generic agency might hand you a WordPress site in 6 months and keep the code. IRPR builds in Next.js or React with a dedicated backend. You own everything.
We also handle compliance (SOC 2, HIPAA, PCI-DSS) and load testing as part of every build. Generic shops often skip these, leaving you with a portal that fails an audit.
- Hourly billing with no cap
- Proprietary code you cannot reuse
- No compliance support
- 6+ month timelines
- No load testing
- CMS-only solutions
- Fixed price from Roadmap onward
- Full source code in your repo
- HIPAA, PCI-DSS, SOC 2 ready
- 8-12 week MVP delivery
- Load tested for 10,000 concurrent users
- React / Next.js architecture
Our 4-phase portal development process
We turn your idea into a working portal in 8-12 weeks.
Phase 1 (Idea): We map user flows, data models, and integrations. You get a written scope and fixed price within 2 weeks.
Phase 2 (Roadmap): We create a detailed build plan with milestones, API contracts, and UI mockups. No assumptions, just exact specs.
What ships with your B2B portal
Every portal comes with production-ready infrastructure and documentation.
You get a fully functional portal, not a prototype. We include deployment scripts, monitoring dashboards, and a post-launch runbook.

- Sentry error tracking and performance monitoring
- Load test results (10,000 concurrent users)
