Senior B2B Portal Development DevelopersSenior Developers
We build custom B2B portals with a fixed price and a 12-week timeline. No junior devs, no hourly billing, no surprises.
IRPR builds B2B portals for companies that need a secure, scalable platform for their partners, distributors, or suppliers. We use Node.js, React, PostgreSQL, and AWS to deliver portals that handle user roles, order management, and real-time inventory sync.
Every portal ships with a fixed price and a 12-week timeline. Costs range from $80K to $250K depending on integrations and compliance needs. We handle HIPAA, PCI-DSS, SOC 2, and ISO 9001 standards.
We work with CTOs at mid-market manufacturers who need a distributor portal, product managers at SaaS companies building a partner portal, and operations directors in logistics who want a supplier portal with EDI integration.

Why senior B2B portal development developers matter
A B2B portal handles complex workflows and high transaction volumes. Junior developers introduce risk.
IRPR only hires senior engineers with 10+ years of experience. Our team has built portals for companies like GE and Siemens. We use proven patterns for role-based access, audit logging, and data encryption.
A typical portal handles 10,000+ transactions per day with 99.9% uptime. We deploy on AWS with auto-scaling and automated backups. Every portal includes Sentry error monitoring and Datadog performance dashboards.
How we differ from generic development shops
Most agencies quote hourly and deliver late. We fix the price and the timeline upfront.
Generic dev shops often assign junior developers to B2B portal projects. They bill by the hour and scope creep is common. IRPR assigns senior engineers only and locks the price after the Roadmap phase.
We also handle compliance. If your portal needs HIPAA or PCI-DSS, we build it from day one. No retrofitting compliance after launch.

Our 4-phase process for B2B portal development
We move from idea to live portal in 12 weeks.
Phase 1: Idea validation. We map user roles, workflows, and integrations. You get a written specification with wireframes.
Phase 2: Roadmap. We define the tech stack, database schema, and API contracts. You get a fixed price and a 12-week timeline.

Full code ownership
You own the source code, the infrastructure, and the IP. We put everything in your GitHub repo. No lock-in, no licenses.
