Architecting High-Throughput B2B & B2C E-Commerce Marketplaces

The Dual-Channel E-Commerce Paradigm

Modern enterprise commerce no longer fits neatly into a single B2C or B2B silo. Organizations operating at scale require hybrid platforms capable of serving individual retail shoppers alongside wholesale buyers negotiating custom quote contracts.

1. Polymorphic Data Models for Dual Pricing

By decoupling product catalog models from cart logic, we created polymorphic transaction handlers capable of switching between instant checkout flows and multi-turn quotation negotiation threads based on user tier and minimum order quantities (MOQ).

2. Multi-Chapter Vendor Settlements & GST Calculations

Managing regional merchant chapters requires automated tax segregation and split payout scheduling. Our settlement engine processes 7/14/21-day cycles with zero manual reconciliation errors.
