If you're adding a new client to SimplePractice and that client already has a balance or credit, you can easily add this amount to his or her account. 

You can create an Initial Balance invoice using our Products feature:

• Add the balance amount to your Settings > Billing and Services > Products page

• Then, create a blank invoice and add your balance to this invoice as a Product

• Your Initial Balance will now be represented by an invoice, which you can choose to pay directly, or at a later time

It will also be clear exactly when that balance is paid, because the invoice will be marked PAID.
