I'm having difficulty getting the slips in the right order. I raise a slip for each day I work on the project. Additional slips for extras eg expenses that relate to that day. I can't always do them day by day. I need the invoice to show the days and charges in the right order. Billings seems to have a mind of its own, and creates a totally random order which I can't drag into order or even make it follow the date of the slips.v Is there a field or something I can add to set the order displayed and then create an invoice my client can understand?
