# Center revenues 💲

> ### <mark style="color:purple;">Each type of center is revenue generating</mark>

**The training center, the laboratory, the nursery**

The income of a training center, a laboratory and the nursery are **stored on a smart contract**.

The owner will then have to go to the Tokens/Claim menu to **claim his BZAI**.

If an owner has different centers, **only 1 claim will be necessary to recover all the income**.<br>

There is no tax at the exit of the incomes of the centers.
