our call

Start with ReturnGO — highest vibe code, weakest moat.

PostCo

Rebuilding the customer-facing return portal and basic exchange rule engine takes days using modern AI dev tools. However, maintaining direct label generation APIs across fragmented APAC logistics providers (Janio, Ninja Van, J&T) creates ongoing engineering drag. Build it yourself only if you rely on major unified aggregators like EasyPost or Shippit.

you can rebuild

  • Branded customer-facing self-service return portal UI
  • Rule-based return eligibility validation based on purchase date
  • Product variant exchange logic and instant store credit generation
  • Admin dashboard for reviewing, approving, or rejecting return requests
  • Automated Shopify webhook processing for order restock and refunds

what you lose

  • Direct out-of-the-box support for regional APAC carriers (e.g., Ninja Van, Pos Malaysia)
  • Turnkey retail and drop-off point network integrations
  • Pre-negotiated carrier return label printing formats and validation
  • SLA maintenance on broken or updated carrier shipping APIs
  • Automated customs declaration document generation for cross-border returns

real moats

  • Pre-built integration engine across fragmented regional shipping networks
  • Localized drop-off location infrastructure partnerships in South East Asia
  • Operational lock-in inside warehouse receiving workflows and SOPs
