Services are allways invoiced in advance. If I set the due date to
1.6.2013 for monthly billing, invoice will be generated for the period
from 1.6.2013 to 30.6.2103 on 1.6.2013. So the client will have to pay
for the following month.
In my case clients use to pay after, what means they expect the invoice for the period from 1.6.2013 to 30.6.2103 on 1.7.2013.
It would be great to be able to invoice after the period.
