Invoicing App weigh-in.
Some of you probably know this but I'm developing an online invoicing app. I'm looking for a little feedback on which feature you would prefer.
Duplicate Invoice: Duplicate any invoice for a customer, tweak as needed.
-----or------
Invoice Templates: Create an unassigned invoice, tweak and assign it to customers as needed.
Which feature would you prefer, and, would you even use the other one?
