The free version of EI calculates the total cost of items on an invoice correctly. I just paid for the new version and after installation noted that the calculation is wrong. I have an item costing 1.4 cents ($0.014) and when I generate an invoice for 20,000 of these items, the calculation returns $200.00 and not $280.00.
I believe this is a bug in the program and I would like someone to issue a patch soon. I have stopped using the paid version and returned to the free one because of this.
