After you have created a sales order, you can create a downpayment invoice from the admin view of this sales order.
1. To do this, click on the Actions button of the sales order and choose "Downpayment Invoice".
2. Next, a pop-up will appear asking you if you want to invoice a fixed amount or a percentage as a downpayment. This calculation works both ways. If you enter an amount, the percentage will be calculated. If you enter a percentage, the amount will be calculated.
3. Once you've clicked on the "Create" button, Akti will display a link to open the downpayment invoice and send it to the customer.
