# Fee models in Control Center

You can use Pismo Control Center to configure fee models and link them to your operations on the Pismo platform. A fee model is a structure that defines a collection of fees with custom calculations. With a fee model, you can define the method used to calculate the fee, such as a fixed value or a percentage. You can think of it as a container for the fees and taxes that are applied to different account activities.

For detailed information about fee models and fees on the Pismo platform, refer to [Fee management](https://developers.pismo.io/pismo-docs/docs/fee-management).
