# Working with revenue
Revenue is the money earned without considering the costs of selling. Revenue can be considered the full cost of the sold goods or services provided.
For example, if the cost of goods is 10,000 and you sold it for 15,000, then:
- Your revenue is 15,000
- Your net profit is 5,000
You can transmit revenue upon conversion in various ways. As a result, you can:
- View personalization statistics in terms of revenue
- Optimize personalizations for revenue
# Ways to transmit revenue
Revenue can be transmitted as the Revenue parameter in client parameters.
This can be done:
On your website via [JS function call] (/guide/integrations/js/custom-user-params.html#write-parameter). The user parameter must be set at any time before the corresponding conversion is triggered.
By calling our API from your backend in the goal achievement method.
Revenue will automatically be transmitted when intercepting:
- Google Analytics ECommerce goals
- DataLayer ECommerce goals (and therefore, Yandex.Metrica)
Finally, you can simply specify a default revenue for the goal in the goal editor.
Revenue sources have the following priorities (from highest to lowest):
- Revenue transmitted as a page parameter
- Revenue transmitted as a user parameter
- Revenue transmitted from intercepted ECommerce goals of Google Analytics or DataLayer
- Default revenue specified for the goal
If you add the Revenue parameter to the client parameter or page parameter,
