In order to create a packing slip, a quote must first be converted into an invoice. This instantly gets added to our creditors list which would be fine if we were a retail outlet, however, we use the packing slip as a substitute for a job sheet and would only like to raise an invoice once a job has been completed in order to mitigate for over-running works, and worksite issues. It should be very simple to duplicate the convert button on the quote screen.
