This article applies to:AvaTax for Communications

If you use customization profiles in AvaTax for Communications to calculate tax for multiple companies or business units that require separate tax calculation settings, it's important to keep your settings up-to-date to match your business requirements.  Learn how to update the settings and customizations assigned to a profile. Changes you make to a profile affect new tax calculations, but don't change the tax amounts on any existing transactions.

Avalara recommends testing all customizations in your sandbox account before you add them to your production account. After you add customizations to your production account, run test transactions or use the tax determination calculator to make sure you receive the expected results before you complete any bill runs.

Each profile is assigned a unique Profile Number that you'll use to apply the settings to a transaction. Review the AvaTax for Communications REST API developer documentation to learn how to use the unique Profile Number.
