To move a deal to the next sales stage of your pipeline, just click and drag the deal along the pipeline, and drop it in the stage you wish for it to be moved into.
When you start dragging a deal, a toolbar appears on the bottom of the page. Drop deals in the relevant boxes at the bottom to mark them as Won or Lost. You can also delete deals or send them to another pipeline.
Note: Completed deals (Won or Lost) will disappear from your Pipeline View, and can still be viewed using your filters or reports.
