B2B Wholesale Marketplace Architecture: Pricing Tiers & RFQs

B2B is Not B2C

When most developers think of "e-commerce," they imagine Amazon or Shopify: a consumer sees a price, adds one item to their cart, and pays with a credit card.

Business-to-Business (B2B) wholesale marketplaces operate completely differently.

If you are building a marketplace connecting industrial manufacturers to commercial retailers, slapping a Shopify theme on it will fail instantly. At DevApps Technology, we architect custom B2B marketplaces that accommodate the complex realities of wholesale procurement.

1. Dynamic Volume Pricing & Customer Tiers

In B2C, a t-shirt costs $20. In B2B, the price of a steel beam depends on three factors:

1. Who is buying? (A Tier-1 VIP customer gets a 15% global discount; a new guest gets MSRP).
2. How much are they buying? (1-10 units = $500/ea; 100+ units = $350/ea).
3. What is their negotiated contract? (The buyer has a specific negotiated price exclusively for SKU #12345).

The Architecture

We build custom pricing engines in Node.js where product prices are never static. The GraphQL or REST API receives a request containing the user_id and product_id, and runs a cascading rules engine to determine the exact price for that specific user at that exact moment.

2. The RFQ (Request for Quote) Engine

In wholesale, many high-ticket items don't have a "Buy Now" button. Prices fluctuate based on raw material costs and global shipping container rates.

We implement robust RFQ (Request for Quote) systems:

• The buyer selects a massive cart of goods and clicks "Request Quote."
• The seller receives the RFQ in their dashboard and calculates custom freight shipping and bulk discounts.
• The seller sends a digital invoice back.
• The buyer approves the quote, which dynamically converts into a payable checkout link.

3. B2B Payment Terms & Net-30 Invoicing

B2B buyers rarely pay for a $150,000 order upfront with a Visa card. They use Purchase Orders (POs) and expect Net-30 or Net-60 payment terms.

We integrate specialized B2B payment gateways (like Stripe Invoicing or custom Plaid ACH integrations).

• Buyers can checkout using a PO number.
• The system automatically generates a PDF invoice.
• Automated email/SMS reminders are fired via Twilio at Day 25, Day 30, and Day 35 to ensure the Net-30 invoice is paid via ACH bank transfer.

4. ERP Integrations

A wholesale marketplace must talk to the manufacturer's internal software. We build bi-directional API bridges between your Next.js marketplace and legacy ERPs like SAP, Oracle NetSuite, or Microsoft Dynamics to ensure real-time inventory synchronization.
