# Typical workflow

Understand the steps involved in using the override.

A typical workflow for using the `taxAmountByTaxTypes` override is as follows:

1.  Calculate customs duty and import tax in a sales invoice.
2.  Ship the item.
3.  Review customs document after the item goes through customs.
4.  Create a sales order (quote) to retrieve the appropriate tax types from the original transaction.
5.  Convert the sales order to a customs invoice.
