Yes it can. It is simply a case of creating an assignment to represent the arrangement and setting it to suit your requirements. If we look at a margin only example, the Costings page of the Assignment Entry should be set to reflect the amount you wish to bill to the client, so you leave the pay section blank and enter the amount of margin-only in the bill section as follows:
You will still need to have a candidate as this is a basic requirement to create an assignment, but as no pay element will exist the timesheets will be used only to generate the bill/invoice amounts.
To process the timesheet with a margin-only situation the easiest way is to select the candidate from the Incoming Images area as follows then select the corresponding timesheet:
Next remove the blank pay line, enter the amount of bill only units, tick 'Invoice without timesheet image' (as you probably do not require any image to validate the timesheet) the click to Validate the timesheet:
The system will display a message as the pay and bill units are not equal - this is a standard message to ensure you are certain you wish to proceed. Click Override to proceed:
The timesheet will now be directed to the Create Sales Invoice area, the same as a standard timesheet, ready to produce a sales invoice. As the timesheet in this example contains no pay element there will be no activity in this area.
The same principles can be applied to Pay Only items - simply enter a pay value and leave the bill amount blank.
