Not certain if this is the right place or not for this.... When at a tradeshow, I will take orders for custom products. I have been having the customer create a form at POS will the relevant information needed for the order. I created a product called CUSTOM ORDER DEPOSIT and would select that option at the POS for the deposit I require. After the product is created I have ben invoicing them for the balance by simply creating another invoice.
Is there a way to create a single invoice at the POS for the total amount and then accept a deposit? I have been using my process because that was the only way I could come up with to expedite the ordering process at a show. The final invoice I send for the balance includes shipping charges because when creating the invoice I enter their shipping information. Using this method, doesn't require me to enter the information at the time of sale which is a little faster.
