I have a mix of clients which according to their business terms need Net billing which I accept. Most are Net 10 while others are NET 30 or Net 5.
I'd like to suggest adding Net terms on a per account basis so the billing only goes out to them on that cycle instead of the global which is set right now for everyone.
We have plans to implement Net D, see CORE-492. It's tentatively assigned to v3.3, but this is not very likely.
