There are two ways to add a record of incoming funds to the system:
1. Use the
Trigger button. See the setup instructions
here.
2. Use the Manage tab.
Go to the order and open the Manage tab. Set the Take payment checkbox and enter the payment amount. Choose the Cash payment type. If necessary, add a comment. Click Process.
After that, the balance changed. And the Payments tab displays information about the payment.
