# Entities

> Learn the Entity data model in Fintoc's Business Accounts API and onboard a Mexican client Entity through the API to hold Account objects on your platform.

An `Entity` is the legal account holder that owns `Account` objects. Your organization always has a root `Entity`. Platforms that hold balances for clients create one `Entity` per client. This section explains what an `Entity` represents and how to onboard one:

* [The Entity data model](/guides/business-accounts/entities/entity-data-model): learn what an `Entity` represents, how the root `Entity` differs from a client `Entity`, and when a compliance review applies.
* [Onboard an entity by API](/guides/business-accounts/entities/onboard-an-entity-by-api): create a Mexican `Entity` for your client and complete its compliance review through the API.

To create `Account` objects under an `Entity` that is already approved, see [Create more accounts](/guides/business-accounts/manage-accounts/creating-more-accounts).
