Why choose a premium B2B portal development vendor
A generic agency builds a portal that breaks. IRPR builds portals that scale.
IRPR has shipped 200+ products across 50 countries. Our B2B portals handle 10,000+ concurrent users, process millions of transactions, and integrate with ERP systems like SAP, Oracle, and NetSuite. We use Next.js for the frontend, Node.js for APIs, and PostgreSQL for data. Every portal includes role-based access, audit logging, and SSO via Auth0.
We charge a fixed price, not hourly. The Roadmap phase (week 2) gives you a fixed quote. No surprises. Our senior engineers work in your time zone overlap hours. You get source code, CI/CD on GitHub Actions, and Sentry error tracking from day one.
The difference between a generic dev shop and a premium B2B portal vendor
Most agencies promise a portal but deliver a mess. IRPR delivers a production-ready system.
Generic dev shops use junior developers, charge hourly, and skip compliance. They build portals that crash under load and fail audits. IRPR assigns senior engineers only, charges a fixed price, and ships with SOC 2, PCI-DSS, or HIPAA compliance built in.
We also handle integrations. Your portal connects to Salesforce, SAP, NetSuite, or Stripe via REST APIs. We write automated tests for every endpoint. Your team gets full documentation and a 30-day warranty after launch.
- Junior developers with 2 years experience
- Hourly billing with no cap
- No compliance documentation
- No CI/CD pipeline
- No load testing
- No post-launch support
- Senior engineers with 10+ years experience
- Fixed price from Roadmap phase
- SOC 2, PCI-DSS, or HIPAA compliance
- CI/CD on GitHub Actions
- Load testing for 10,000 concurrent users
- 30-day warranty and 99.9% uptime SLA
How IRPR builds your B2B portal in 8-12 weeks
We follow a 4-phase process: Idea, Roadmap, Product, Release.
Phase 1 (Idea) takes 1 week. We map your workflows, user roles, and integration points. Phase 2 (Roadmap) takes 1 week. We deliver a fixed price quote, a technical architecture document, and a 12-week timeline.
Phase 3 (Product) takes 8-10 weeks. Our team builds the portal in 2-week sprints. You see progress every sprint. Phase 4 (Release) takes 1 week. We deploy to production, run load tests, and hand over source code.
