Operating each channel separately creates common failures: wrong stock, delayed shipping status, and inconsistent customer communication. Integration is a synchronization problem before it is a coding problem.

What must stay in sync

  • Products and variants
  • Prices and promotions
  • Inventory quantity
  • Orders and statuses
  • Customer profile
  • Invoices and fiscal data
  • Tracking lifecycle

Recommended integration architecture

  1. ERP as system of record
  2. Event queue for state changes
  3. Webhooks for near real-time updates
  4. Retries with dead-letter queue for failures
  5. Centralized logs and alerts

Common integration mistakes

  • Missing idempotency and duplicate order processing
  • Weak payload versioning
  • No reconciliation jobs
  • Webhooks without retry strategy

Preventing overselling

  • Reserve stock before checkout confirmation
  • Reject orders when stock is inconsistent
  • Automatically reconcile and flag divergence

Safe migration plan

Use phased rollout: read-only sync, then controlled write operations, then full automation. Keep rollback per stage.
