If you work like we do, you take money up front from your clients. After receiving that deposit, you should enter it inside Cashboard as a payment.

Navigate to the Accounting tab, then click the large Record Payment button on the right hand side. Enter in the payment information then save.

You’ll notice that your Account Balance screen has now been updated to reflect that you’ve taken a deposit.

When you are ready to invoice this client you can apply the payment right from the invoice Items & Payments screen, as shown below.

Clicking the Apply Payment button or link will bring up this screen, which will allow you to apply existing credits to the invoice in question, or record a new payment.
