I normally use a task management system until I took the leap and started using this for 2 days now. GREAT TOOL (Can't believe how ingenious this is). If you add a check box, then it would grey (preferable) or hide checked items so I know i have entered them into my invoice database which I have made. This could be quickbooks for other people. This way I can enter everything by day and know i have taken care of everything, then my invoice tool organizes in a different way and I can use Quickbooks to invoice from there. Adding another checkbox to mark that there was mileage and another for expenses would be great too.
