See how IRPR builds B2B e-commerce platforms for wholesale, distribution, and manufacturing. Read client reviews of our 8-12 week delivery process.
IRPR builds custom B2B e-commerce platforms for businesses that need more than a standard Shopify store. We use Next.js, PostgreSQL, and Stripe to create headless commerce systems that handle complex pricing, bulk orders, and multi-warehouse inventory.
Each project ships in 8-12 weeks with a fixed price between $80K and $250K. All platforms meet PCI-DSS Level 1 compliance for secure payment processing.
We work with wholesale distributors who need custom pricing tiers, manufacturers who sell direct to businesses, B2B brands migrating from legacy ERP systems, and marketplace operators who need multi-vendor support.

Custom B2B e-commerce platform vs generic e-commerce
A custom B2B e-commerce platform solves problems that off-the-shelf software cannot.
Generic platforms like Shopify or BigCommerce lack support for tiered pricing, bulk discounts, and punchout catalogs. They also charge transaction fees that eat into margins on high-volume B2B orders.
IRPR builds custom B2B e-commerce platforms from scratch using Next.js, PostgreSQL, and Stripe. You own the code, control the features, and pay no per-transaction fees.
- Uses pre-built themes with limited customization
- No support for complex B2B pricing rules
- Charges monthly SaaS fees plus transaction fees
- No punchout or ERP integration expertise
- Delivers in 16-24 weeks with scope creep
- You do not own the source code
- Builds headless commerce with Next.js and Stripe
- Custom pricing engines with volume tiers and contracts
- Fixed price, no hidden fees, no transaction fees
- Native integrations with NetSuite, SAP, and Coupa
- Delivers in 8-12 weeks with a clear roadmap
- You own 100% of the code and IP
How we build your custom B2B e-commerce platform
Our process delivers a production-ready platform in 8-12 weeks with no surprises.
We start with a 2-week Roadmap phase where we define the product backlog, tech stack, and fixed price. You get a detailed specification before any development begins.
Then we build in 2-week sprints with a dedicated team of senior engineers. You see working software every sprint and can adjust priorities as needed.
