Why you need an expert B2B portal development partner
A custom B2B portal replaces spreadsheets, emails, and phone orders with a single platform your partners actually use.
IRPR has shipped over 200 products for clients in 50 countries. Our B2B portals handle complex pricing, multi-currency orders, and real-time inventory sync. We use React for the frontend and Node.js or Python for the backend, with PostgreSQL or MongoDB for data storage.
Every portal includes automated order confirmation emails, role-based access controls, and audit logging. We integrate with Salesforce, SAP, NetSuite, QuickBooks, and Stripe. Compliance is built in from day one for HIPAA, PCI-DSS, or SOC 2.
The difference between a generic dev shop and an expert B2B portal development partner
Not all agencies can handle B2B portal complexity. Here is what sets IRPR apart.
Generic dev shops often build portals that break when pricing rules get complex or integrations fail. IRPR builds portals that scale with your business.
We assign senior engineers only. No junior developers. Every project has a dedicated project manager and a technical lead who stays with you from Roadmap to Release.
- Hourly billing with no fixed price
- Junior developers on your project
- No compliance expertise (HIPAA, PCI)
- Custom integrations cost extra
- No post-launch support plan
- Code ownership unclear
- Fixed price from week 2
- Senior engineers only (7+ years avg)
- Built-in HIPAA, PCI-DSS, SOC 2 compliance
- Salesforce, SAP, NetSuite integrations included
- 12-month support and maintenance option
- Full source code ownership
Our process for building your B2B portal
We follow a 4-phase framework: Idea, Roadmap, Product, Release. Each phase has clear deliverables and a fixed budget.
Phase 1 (Idea) takes 1 week. We map your business rules, user roles, and integration points. Phase 2 (Roadmap) takes 1 week and produces a detailed scope with a fixed price.
Phase 3 (Product) is the build phase. For a B2B portal, this typically takes 8-12 weeks. Phase 4 (Release) includes deployment, testing, and a 30-day warranty.
What ships with your B2B portal
Every portal includes a standard set of deliverables. No hidden extras.
You get the source code in your own GitHub repository, a CI/CD pipeline, and a staging environment. Documentation covers API endpoints, database schema, and deployment steps.
We also include error tracking (Sentry), performance monitoring (Datadog), and automated tests. Your team can take over immediately or we can continue with a support retainer.
- Source code in your GitHub repo
- CI/CD pipeline on GitHub Actions
- Sentry error tracking
- Datadog performance monitoring
- API documentation (Swagger/OpenAPI)
- Database schema diagram
- Deployment runbook
- Admin panel for managing users and orders
- Role-based access control (RBAC)
