Project Flex Time is a wonderful addition to Project Time & Expense
If you are using Project Controller Time and Expense and have not yet upgraded to SL 7.0 FP1 - you need to do it now. Microsoft added Project Flex Time and it is fantastic! The previous version limitations of one week time cards has always been a source of angst, but the new Project Flex Time in Time and Expense let's you define your time card periods to match your pay periods. This is a huge improvement to T&E. It is simple to setup and use and your staff will easily pick up the new look and feel.
It comes with FP1 so you don't have to license it and the setup really is simple. Within one hour you can have it functioning for your staff.
