  • Real-time inventory level synchronization across storefronts
  • Automated purchase order creation upon store checkout
  • Fulfillment status and tracking number sync back to merchant store
  • Multi-store product catalog attribute and pricing markup rules
  • Automated CSV/XML supplier catalog ingestion

what you lose

  • Access to 1M+ pre-vetted products from established US/EU/UK suppliers
  • Pre-negotiated wholesale pricing and automated escrow wallet payments
  • Enforced supplier SLAs for 24-48 hour dispatch times
  • Unified supplier dispute, refund, and return management center
  • Zero-maintenance inventory connections with hundreds of independent brands

real moats

  • Two-sided supplier and merchant network liquidity
  • Pre-negotiated dropship supply chain contracts and SLAs
  • Automated supplier payment settlement and escrow workflow
