We sometimes use the billing for hourly rates. It would be useful to be able to bill for time that is less than (or more than depending on how you roll) an hour, say 30 min as .5 hrs or something along those lines. As it is now, we have to create separate items in order to bill properly, otherwise the invoice appears as though we are giving a discount, when we are not doing so. Making our item list more cumbersome.
This is important to note it is not a discount, because when the invoices are moved to an accounting platform, a discount is noted as something entirely different than money earned for tax purposes.
