our call
Start with PostCo — 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
