# Price Calculation

To calculate the price for each shop item without submitting an order, you can simulate the process heavily described in [Order Invoice](https://neomsolutions.gitbook.io/gifthub-api-doc/shop/broken-reference) .

You will need the bellow entities: 

* **Exchange Rates**: Track the exchange rates from the [customer information](https://neomsolutions.gitbook.io/gifthub-api-doc/customer/customer-information) API. 
* **Customer Deal**: Track the customer deal applied to the specific product via the [Shop List](https://neomsolutions.gitbook.io/gifthub-api-doc/shop/shop-list) API.
