# Customer supplier name

Understand how to specify the customer or supplier name in the customerSupplierName field for transactions.

This topic is specific to the VAT marketplace solution.

**Element type:** Suggested

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

Your integration should provide an option for specifying the name of the customer or counterparty who is purchasing the goods or service. For sales document types, enter the name of your own company for which you’re reporting in the `customerSupplierName` field; for purchases document types, enter the name of the supplier you’ve purchased from in the `customerSupplierName` field.

Keep in mind the following when entering a `customerSupplierName`.

-   If the customer supplier is a company, then the company name and legal form should be passed (for example, `Final Customer GmbH`).

-   If the customer supplier is a private individual, then you may choose to use an ID, you can pass a full name, or you can simply use `PRIVATE INDIVIDUAL`.

-   AvaTax doesn't validate this field; it only passes this value back in reports that are designed for audit purposes, such as the Marketplace Audit Report found in the **Reports** section in the AvaTax UI.
