AvaTax provides a method for performing invoice currency conversion. This optional feature supports use cases where a customer needs to provide their local tax authority with the invoice tax details in a local currency. The `exchangeRate` option is used in this feature to provide the exchange rate between the transaction currency and the company base currency.
