# Foreign Cash

## What is this?

The Foreign Cash extension lets you allow for customers to pay in foreign cash, like Euro or US dollar.

## How does it work?

Simply define a currency exchange rate between what is your base currency (e.g. "NOK" for Norwegian Kroner) and the relevant currencies you want to allow for paying in.

All sales are fulfilled in the base currency, and so any rounding is done directly on the sale.

{% hint style="warning" %}
Agio and other such things are not taken into consideration, and needs to be handled from within the accounting system.
{% endhint %}

## How do we get started?

Add the various currencies wanted, alongside the relevant exchange rate.

Enable the Foreign Cash payment method in the store(s) where you want to allow for this.

{% hint style="info" %}
The exchange rates must be administered manually. The reason for this is that practically everyone wants to control the exchange rate themselves, and so then having an automation for import/sync of the exchange rates simply only adds complexity to the platform.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.flowretail.com/docs/day-to-day-operations/selling/payments/payment-methods/foreign-cash.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
