What is WUD?

WUD stands for Write-up/Write-Down. It is a value or percentage at which billable hours are written up or down. It is the equivalent of markup for expenses. You can write up/down the value of time entries in various ways: by applying WUD at the time entry level or by changing the value of net bill while invoicing. Changing the value of WUD to 0%, resets the original value of time entries.
