# Prices

> For the complete documentation index, see [llms.txt](https://doc.ibexa.co/en/saas/llms.txt).

The price engine calculates product prices taking into account customer groups, currencies and taxes.

The price engine is responsible for calculating prices for products in the [product catalog](https://doc.ibexa.co/en/saas/product_catalog/product_catalog/index.md).

## Custom pricing

You can set up basic price rules depending on [customer groups](https://doc.ibexa.co/en/saas/users/customer_groups/index.md).

Use this option to globally manage custom prices, for example for your resellers. Each customer group can have a default price discount that applies to all products.

## Currency

Cohesivo ships with a list of available currencies, and you can also add custom currencies. To use currencies in your shop, you need to first enable them in the back office.
