# How are bank accounts handled?

Bank account numbers can be configured per contract. The number can also have reviews turned on so that any changes are only with approval.

When hovering over the field on the contract "details" tab, you can click on the dots to "enable review":

If a bank account number is to be collected on a registration form, application form or milestone form, a short text field can be used with a "Bank Account" format, as follows:
