# How do I use company profiles?

Learn how company profiles determine tax calculations and manage business-specific settings in AvaTax.

A company profile includes key information about your business. This information determines how AvaTax calculates tax and includes the following:

-   Where you collect and pay tax

-   The products and/or services you sell and where you sell them

-   Customers that you exempt from tax, if any

If your business has more than one company, you can create other company profiles at any time for a single AvaTax account. When creating transactions, the company code is what designates the profile that processes a transaction. If no company code is present in the request, whatever company profile is flagged as the default will process that transaction.
