Internal Payment
This card type is currently used only for creating Internal Payments. Existing internal payments still follow the external payment card format and rely on the Opposite Payment field for linking.
The key feature of the Internal Payment card is the ability to define bank accounts for both sides of the transaction, since both the sender and the recipient are own companies (from the admin panel).

Specific Fields

Counterpartyfield.Bank Account From: Bank account of the sending company.
Bank Account To: Bank account of the receiving company.
Amount From: Amount to be debited from the sender's account.
Amount To: Amount to be credited to the recipient's account.
The Account Balance for each bank account is displayed next to its respective field.
