Hi Sean, we use Cash Sales - oddly enough, if you select the payment method "Credit Card" on a Sales Order, it creates a Cash Sale (CS) instead of an Invoice. Cash Sales, I believe, are booked immediately and they don't have a billing status of Open - so once billed it's all good. Handy way to distinguish between the two ways of getting paid (pre- vs post-payment.) The nice thing is you could automate it in just two steps - build a workflow to change a group of orders' payment method to credit card, and then once fulfilled, automatically bill them to cash sales (but again only based on the original criteria.)
