## Multiple Currency Setup

NATS records all transactions in its base currency. This base currency, which is usually set to U.S. Dollars (USD), is set during the installation of your NATS build and cannot be changed. NATS only records transactions in its base currency, but you can create join options that will accept other countries. However, you must first tell NATS what exchange rate to use.

To set your exchange rates go to the [Configuration Admin](/nats-admin/configuration.md), select "Currency - All" from the drop-down menu, and click Change Section. On the next page, find the currency you want to accept and fill in the current exchange rate. 

{% hint style="danger" %}
**Important:** You must update this currency table whenever exchange rates change, as NATS will not automatically update them for you. 
{% endhint %}

Some 3rd Party Billers can allow you to set up just the USD setting in NATS, but based on Biller Code, Biller's page displays, charges in different currencies, and more, then reports back to NATS with the USD. In this case, NATS doesn't handle conversion at all.&#x20;

Some Billers will report back the EUR amount, and NATS will convert to USD due to it needing to record everything in USD.&#x20;
