Why choose an expert B2B portal development company
Generic web agencies build brochure sites. We build transaction platforms that process millions in revenue.
A B2B portal is not a simple website. It handles complex pricing tiers, multi-role permissions, purchase order workflows, and integrations with ERP systems like SAP and Oracle. IRPR has shipped 200+ products across 50 countries, including portals for manufacturers, distributors, and logistics firms.
Our portals are built with React and Node.js on AWS, with 99.9% uptime guaranteed. We follow HIPAA, PCI-DSS, and SOC 2 compliance standards. Every portal includes automated testing, CI/CD pipelines, and real-time monitoring with Sentry.
The difference between a generic agency and an expert B2B portal development company
Most agencies sell you a template. We build a portal that fits your business model.
A generic agency might give you a WordPress site with a shopping cart plugin. That works for a small retailer. But a B2B portal needs custom pricing rules, approval workflows, and real-time inventory sync across multiple warehouses.
IRPR builds portals that handle complex business logic from day one. We use event-driven architecture on AWS Lambda and API Gateway to scale automatically as your transaction volume grows.
- Starts with a CMS template
- No custom pricing engine
- Manual order processing
- Basic user roles (admin/user)
- No ERP integration
- Hourly billing with scope creep
- Custom-built with React and Node.js
- Multi-tier pricing and discount rules
- Automated PO and invoice workflows
- Role-based access for suppliers, buyers, and admins
- Direct integration with SAP, Oracle, and NetSuite
- Fixed price, 8-12 week delivery
How we build your B2B portal in 8-12 weeks
Our process is designed to de-risk your investment and get a working portal in your users' hands fast.
We follow a four-phase process: Discovery, Roadmap, Build, and Release. In the first week we map your workflows and identify the critical path. By week 2 you have a fixed price and timeline.
During the Build phase we ship working software every two weeks. You see progress in a staging environment. We handle all integrations, testing, and deployment. The Release phase includes load testing, security audit, and go-live support.
