The director of catering sets up the event file once: these seven documents belong to every event, and the event number ties them together. In Content Central this is a packet template.
From then on nobody builds the file. The signed contract, the deposit receipt from accounting, the band's certificate of insurance scanned at the front desk: each one joins EVT-0614 the moment it is filed with that number.
The BEO changes four times. Each change is a new version of the same document, so the kitchen, the banquet captain and the client all open version 4, and versions 1 to 3 are still there if anyone asks what changed.
On Thursday the file still shows the final guarantee as missing, so a reminder goes to the event manager. When the banquet check arrives Sunday morning, the file turns complete. That sends the final invoice to the controller and merges everything into one PDF for the client.
