Managing Pre-payments
You can accept pre-payments In cases where a customer sends you a payment but you don't have an invoice. All pre-payments go to a customer's cash account. You can also apply the pre-payments to specific order and line items. Applying pre-payments to order/line items will make sure any pre-pay is applied to an invoice as soon as you create it. So you won't have to go re-apply the payment.
All pre-payments start with applying an amount to a customer's cash account. To put money on the customer's cash account, go to the Quick Add > Add Payment.
Enter the name or the ID of the company. Scroll down to the bottom of the page to enter the payment. You must select Cash Account in the Apply To field.
Enter the method, amounts, and either record or process the payment. You process credit card and ACH accounts for pre-payments.
There is an option to apply a pre-payment directly to an order. You can only apply a pre-payment to an order if it hasn't been invoiced. If you pick an order, any available cash account balance will be applied against invoices created for any line item on the order.
Now that you have money on your Cash Account, you can start applying it to orders and line items.
Caution
Money on the cash account can be applied to any invoice in the system. It is possible for you to apply a cash account amount to an invoice that is associated with a different order.
