Hi Bluepenny!

Yep, totally automatic if you haven't already processed a prior order.

That's kinda my problem - I have customers buying 2-6 items, but not always immediately. However, since I am setup for "immediate payment only", I often end up with multiple invoices for the same customer. (Like if they buy more items later in the day).

So, at least for me, the ability to have an option to merge invoice with existing invoices that have been paid (but not shipped) would be really nice :)
