When monthly contracts are parsed to QB, the line items do not include dates. This is problematic when more than a month has elapsed from the generation of one invoice to another and certain contracts have entered the next period. The client receives two line items exactly the same. It looks like an error, when in fact it is the billing for the previous month and the next month. If the billing period information (which is clearly displayed in the invoice batch) was passed onto the QB invoice, it would solve untold headaches.
