Under the More Menu on the Main Tab of an order in XOMS, you will see an option Create Deposit Request. This option will allow you to choose a percentage 0%-100% to send to your customer for payment on orders before they are invoiced.
This can often be more beneficial than pre-billing your customers, as they will still receive a final invoice with any changes in price that may have occurred, and it also does not start the “invoicing” clock. Additionally, pre-billing customers can remove the order from internal follow up reports, and locks it from future edits until it is re-opened.
