A down payment is an initial, partial payment, with the agreement that the rest will be paid later. For expensive orders or projects, it is a way to protect yourself and make sure your customer is serious.
First time you request a down payment
When you confirm a sale, you can create an invoice and select a down payment option. It can either be a fixed amount or a percentage of the total amount.
The first time you request a down payment you can select an income account and a tax setting that will be reused for next down payments.
You will then see the invoice for the down payment.
On the subsequent or final invoice, any prepayment made will be automatically deducted.
Modify the income account and customer taxes
From the products list, search for Down Payment.
You can then edit it, under the invoicing tab you will be able to change the income account & customer taxes.
