Senior B2B Portal Development AgencyDevelopment Agency
We build custom B2B portals for manufacturers, distributors, and logistics companies. 8-12 week MVP, fixed pricing, senior engineers only.
IRPR builds B2B portals for companies that need to connect suppliers, distributors, and customers on a single platform. We use React, TypeScript, Node.js, and PostgreSQL to build portals that handle complex pricing, inventory sync, order management, and role-based access.

Why you need a senior B2B portal development agency
Off-the-shelf portals like Magento or BigCommerce cant handle complex B2B pricing, approval workflows, or ERP integrations.
A B2B portal is not just a storefront. It needs to integrate with your existing ERP (Microsoft Dynamics 365, SAP, Oracle NetSuite), handle tiered pricing per customer, manage purchase orders instead of credit cards, and support multiple user roles with granular permissions. That requires a senior team that has built these integrations before.
IRPR has shipped 200+ portals and apps across 50 countries. Our senior engineers have deep experience with React, TypeScript, Node.js, and PostgreSQL. We build portals that scale to 10,0000+ users and sync data in real time with your ERP and CRM.
How we build B2B portals differently
Generic dev shops hand you a time-and-materials estimate and disappear. IRPR gives you a fixed price, a roadmap, and a senior team that ships.
Most agencies start coding before they understand your business. They use junior developers, bill by the hour, and deliver late. You end up with a portal that doesnt integrate with your ERP and a contract that has no end.
IRPR starts with a Roadmap phase where we define scope, tech stack, and timeline. You get a fixed price quote in week 2. We use senior engineers only (mid-level or higher). Every project ships with source code ownership, a CI/CD pipeline, and 30 days of support.
- Hourly billing - no price cap
- Junior or mixed-level teams
- No dedicated project manager
- No ERP integration experience
- No post-delivery support
- Source code not always transferred
- Fixed price from Roadmap (week 2)
- Senior engineers only (7+ years avg)
- Dedicated senior PM
- Deep ERP integration: SAP, Oracle, Dynamics
- 30 days free support included
- Full source code ownership
Our B2B portal development process
We use a 4-phase process that gets you to launch in 8-12 weeks with zero ambiguity.
Phase 1 is the Idea phase where we align on goals, user roles, and integration requirements. Phase 2 is the Roadmap - you get a detailed project plan with wireframes, tech stack, and a fixed price.
Phase 3 is Product - we build the portal in 2-week sprints with daily standups, progress demos, and automated tests. Phase 4 is Release where we deploy to your cloud (AWS, Azure, GCP) and hand over source code and documentation.
What ships with every B2B portal
Every B2B portal we build comes with a full set of deliverables - not just code.
You get source code in your private GitHub repo, a CI/CD pipeline on GitHub Actions or GitLab CI, and infrastructure as code for AWS or Azure. No vendor lock-in.
We include automated tests with Jest and Cypress, error monitoring with Sentry, and a deployment runbook. Your team can take over on day one.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Infrastructure as code (Terraform / CloudFormation)
- Automated test suite (Jest, Cypress)
- Sentry error and performance monitoring
- Deployment runbook and architecture docs
- Postman collection for API endpoints
- 30 days free support after launch
What we ship in this practice.
Supplier collaboration portal for an industrial parts manufacturer

Partner portal for a SaaS logistics platform
The platform had 150+ 3PL partners who needed to log in, upload rates, and track shipments. We built a portal with Azure AD SSO, automated commission calculations, and a real-time tracking map. Partner onboarding time dropped from 2 weeks to 2 days. Tech stack: React, Node.js, PostgreSQL, Azure.
Wholesale ordering portal for a food service distributor

Customer portal for a medical device manufacturer
Hospitals and clinics needed to reorder devices, view service records, and submit warranty claims. The portal required HIPAA compliance and SSO with hospital IDPs. We delivered in 10 weeks with full HIPAA audit readiness. Tech stack: React, Node.js, PostgreSQL, Auth0.
