It seems that in OpenERP 7.0, the due date for an invoice is calculated
from the current time when it was validated, not the invoice date. In
our business, if a customer wants an invoice backdated (usually so they
can cram expenses into a budget period at the last moment), they must
also accept that we won't give them as much time to pay, since we would
calculate the due date as 30 days from whatever invoice date they want.
Do other businesses not do the same? Is there any trivial way to change
this behaviour or should I look at a custom module?
