Web Expense is an add-on module designed to work seamlessly with both Web TimeSheet editions Project & Billing and Time & Attendance.

When users fill their Expense sheet (and is using only Project & Billing edition or using a combination of both Project & Billing and Time & Attendance editions), they can see a Client filter and Project filter on the Expense Sheet whereas, users using only the Time & Attendance module don't see the Client and Project filters on their expense sheet.
