I am moving to NXT from Quickbooks and one item I very much missed is the calculator functionality within a money field. When entering invoices many times I would have many lines of expenses that go to the same account. It was nice to be able to add up all the numbers in the field and just have one line on the entry. With NXT I either have to enter in numerous lines for each charge or add it up outside of the system first and then enter it as one line. This calculator functionality also worked within journal entries as well. It would be nice if NXT had that option too.
