# Price Calculation

To calculate the price for each shop item without submitting an order, you can simulate the process heavily described in [Order Invoice](broken-reference) .

You will need the bellow entities:&#x20;

* **Exchange Rates**: Track the exchange rates from the [customer information](../customer/customer-information) API.&#x20;
* **Customer Deal**: Track the customer deal applied to the specific product via the [Shop List](shop-list) API.
