Here, you'll find:

* [**Accounts**](/en/midaz/accounts): The core financial unit in a Ledger. Each Account uses one Asset and records its debits, credits, and balances. Midaz also supports External Accounts to track value that moves in or out of your organization.

* [**Portfolios**](/en/midaz/portfolios): Groups of Accounts that belong to one entity, such as a customer or business unit. A Portfolio works like a wallet that holds that entity's Accounts across different Assets.

* [**Segments**](/en/midaz/segments): A classification for Accounts that share characteristics. You group Accounts into Segments to organize them by tier or type, such as premium card tiers or student accounts.
