Exempt customers from sales tax in AvaTax for Communications

When you add an exemption number to a transaction, AvaTax for Communications exempts the customer from sales tax for the transaction. An exemption certificate number identifies a buyer as exempt. If you regularly sell to tax-exempt customers, you need to consistently exempt their purchases. You also need copies of all of your customers' exemption certificates in case of an audit.
