Building a two-sided B2B marketplace requires fundamentally different architecture than standard e-commerce. Avoiding these common traps is vital for survival.

1. Scope Creep Trap

Attempting to build automated bidding, credit lines, and multi-tier logistics before proving transaction volume. The winning model: launch the core workflow in 3-4 months.

2. Enterprise Role Management

B2B deals require multi-user approval trees (CFO, procurement officer, warehouse manager). Without rigid RBAC, enterprise clients cannot pass compliance.
