Custom B2B E-commerce Development FirmDevelopment Firm
We build custom B2B ecommerce platforms that handle complex pricing, catalogs, and buyer workflows. Ship in 8-12 weeks with fixed pricing.
IRPR builds custom B2B ecommerce platforms using Next.js, Node.js, and headless commerce APIs like Shopify Plus or custom GraphQL backends. We handle complex B2B requirements: tiered pricing per account, bulk ordering, purchase orders, and multi-warehouse inventory.
Every project ships in 8-12 weeks with a fixed price between $80K and $250K. Our platforms are PCI-DSS compliant and integrate with ERP systems like NetSuite and SAP. We also meet SOC 2 standards for SaaS B2B clients.
Manufacturers needing a wholesale storefront, distributors looking to automate ordering, enterprise procurement teams requiring a custom portal, and B2B SaaS companies wanting a subscription commerce platform all hire us. We replace outdated systems with modern, scalable solutions.

Why custom B2B ecommerce development matters
Off-the-shelf platforms fail when your pricing, catalog, and buyer workflows are unique.
Generic ecommerce tools like Shopify Standard or WooCommerce lack B2B essentials: per-customer pricing, bulk ordering, purchase order support, and ERP integration. IRPR builds custom B2B platforms that match your exact business rules.
We have shipped 200+ products across 50 countries. Our B2B clients see 40% faster order processing and 30% fewer support tickets after launch. Every platform is built with Next.js, Node.js, and PostgreSQL on AWS with 99.9% uptime.
The difference between IRPR and a generic ecommerce agency
Most agencies build B2C sites and call it B2B. We build for B2B from day one.
Generic shops use templates and plugins to fake B2B features. That leads to slow performance, broken workflows, and months of rework. IRPR engineers have built B2B systems for manufacturing, distribution, and healthcare clients.
We start every project with a 2-week Roadmap phase that defines your exact pricing rules, catalog structure, and integrations. You get a fixed price and a clear timeline before any code is written.
- charges by the hour, no fixed price
- uses standard templates with B2B plugins
- no experience with tiered pricing or POs
- slow performance under high catalog loads
- no ERP integration expertise
- hands over code without documentation
- fixed price per project, no surprises
- custom headless architecture built for B2B
- senior engineers who have built B2B systems for 15+ years
- handles 1M+ SKUs and complex pricing rules
- native integrations with NetSuite, SAP, and Salesforce
- full code ownership + CI/CD pipeline + documentation
Our B2B ecommerce development process
We ship custom B2B platforms in four phases with no surprises.
Every engagement follows the same structure: Idea, Roadmap, Product, Release. This ensures you know exactly what you're getting and when it ships.
During the Roadmap phase (week 2), we define every pricing rule, catalog hierarchy, and integration endpoint. You approve the plan, and we build to it.
What ships with your custom B2B ecommerce platform
You get more than a website. You get a production-ready system with full ownership.
Every B2B project includes the frontend, backend, integrations, and infrastructure. We hand over everything your team needs to run and extend the platform.
Our delivery includes automated tests, monitoring, and documentation. No handoff gaps.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions with automated tests
- Sentry error tracking with alerts
- AWS cloud infrastructure (ECS, RDS, CloudFront)
- PostgreSQL database with migrations
- Stripe or custom payment integration
- NetSuite or SAP integration via REST APIs
- Load testing report showing 99.9% uptime under traffic
- Admin dashboard for managing users, orders, and pricing
- Technical documentation and runbooks
