# Point-of-order origin address (header and line levels)

Learn about the point-of-order origin address and how to use it in transactions.

**Endpoints/models used:** [AddressesModel](https://developer.avalara.com/api-reference/avatax/rest/v2/models/AddressesModel/)

Your integration must provide a way for users to enter a point-of-order origin address at the header or line levels of a transaction. In some systems, this field is represented as the "Bill To" address. It represents the location from where your customer (home or business) placed the order to you. This is used to determine the establishment country of your customer. You can add a point-of-order origin address to your application using the `pointOfOrderOrigin` field in the [AddressesModel](https://developer.avalara.com/api-reference/avatax/rest/v2/models/AddressesModel/).

Note

Include point-of-origin-addresses on Sales type documents only.
