our call
Start with ReturnLogic — 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

- 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
ReturnLogic
Building a customer-facing return portal and basic exchange generator is straightfoward using Shopify Admin GraphQL APIs. However, maintaining reliable carrier API connections for shipping label generation, handling warehouse inspection workflows, and managing complex inventory disposition sync across external systems requires sustained engineering effort.

- Configurable return window rules engine
- Return reason survey collection and basic analytics dashboard
- Shopify exchange draft order generation via GraphQL API
