Why choose a professional B2B portal development vendor
IRPR has shipped over 200 products across 50+ countries, including complex portals.
We build portals that handle thousands of transactions per day. Our team of senior engineers writes clean, testable code from day one.
Every portal includes CI/CD pipelines, automated monitoring, and 99.9% uptime SLAs. We support OAuth 2.0, SAML, and OpenID Connect for secure authentication.
The difference between IRPR and generic development shops
Most agencies promise custom portals but deliver buggy, unscalable code.
Generic shops reuse the same template for every project. They cut corners on security and performance, leaving you with a portal that breaks under load.
IRPR treats each portal as a unique product. We design the data model, API architecture, and auth flow from scratch based on your business rules.
- Reuses template code from previous projects
- No dedicated security review
- Average engineer has 2 years experience
- Hourly billing with no fixed quote
- No CI/CD until month 4
- Code ownership is unclear
- Custom architecture for each portal's data model
- Security audit in the Roadmap phase (week 2)
- Senior engineers only (10+ years average)
- Fixed price based on clear Roadmap document
- CI/CD pipeline set up by day 10
- Full source code in your repo from day 1
How we build your B2B portal in 4 phases
Our process guarantees on-time delivery with no surprises.
We start with a 2-week Roadmap phase to define every feature, integration, and compliance requirement. You get a fixed price and timeline before we write a line of code.
Then we build in 2-week sprints with daily stand-ups and weekly demos. By week 12, you have a production-ready MVP that you can deploy.
What ships with every B2B portal we build
You own everything from day one.
You get a complete, deployable system. No hidden tools or third-party lock-in.
All deliverables are documented and tested. Your team can take over maintenance immediately after launch.
- Source code in your private GitHub repo
- CI/CD pipeline via GitHub Actions
- Sentry error tracking and performance monitoring
- Unit tests with Jest and Cypress for E2E
- Docker containers and Kubernetes manifests
- API documentation auto-generated from OpenAPI spec
- User authentication with Auth0 (or your IdP)
- Database migrations and seed scripts
- Readme with setup instructions and architecture notes
- 99.9% uptime SLA with 1-hour response time
