Account Types are configured in Setup / Users & Accounts / Accounts / Account Types
Account types are used to classify accounts (partner, enterprise, etc.). Account types are useful for reporting purposes, allowing you to filter data down to particular accounts (e.g. view revenue from corporate customers only). An account type is selected during account creation but it can be changed after the account has been created (on the Account > Overview > Settings > account screen).
Account types can be setup immediately, there are no prerequisite configuration steps.
The Account Types panel on the left of this screen allows you to select existing types to view and edit on the Edit Account Type panel to the right. Actions are also available in this panel which are shown as icons above the Filter text box. The available actions are described below.
Deletes the account type if not in use (set on an account)
Adds a new account type
The information in this panel reflects the currently selected account type. From here you can change account type details (fields will display a red left border if a value is required and purple text if the field is read-only and cannot be modified).
Account Type Fields:
Name: a unique and descriptive name for the account type (e.g. Enterprise)
Default: if set the account type will be selected by default when creating a new account
This section displays where the selected account type is used in the system. By default the reference data is displayed in a summary format to indicate where the account type is in use, however the Entity drop down field can be used to view the exact system objects that the account type is configured on.
