Order Management

Manual Tax Calculations

When you need to manually calculate taxes:

  • Edit an order in WooCommerce admin
  • Click the "Recalculate Taxes" button
  • Zamp will automatically fetch a sales tax calculation based on the order's properties
  • Review calculated tax amount before saving

Refund Processing

Refunds are automatically processed through Zamp when issued in WooCommerce:

  1. Open the order you want to refund
  2. Click the "Refund" button
  3. Enter refund amounts
  4. Submit refund

Important: Refunds will only process in Zamp if the original transaction was successfully synced.

Order Status Integration

Zamp Tax integrates with the following WooCommerce order statuses:

  • Processing - Initial tax calculation and transaction sync
  • Completed - Final transaction sync to Zamp
  • Refunded - Triggers refund sync to Zamp

Transaction Status Tracking

Monitor transaction sync status in the order details:

  1. View order in WooCommerce admin
  2. Look for "Zamp Transaction Status" meta box
  3. Status will show:
    • "Success" - Transaction synced successfully
    • "Failed" - Transaction failed to sync
    • "Pending" - Transaction waiting to sync
  5. Use "Resend" button to retry failed transactions
