An event enquiry has a date attached, and dates do not negotiate
The hold is the most fragile thing in your business
Every serious enquiry starts with a date question. The client asks whether you are free on the fourteenth, someone says yes and mentally blocks it, and that is the entire record. Two weeks later a second enquiry arrives for the same weekend and nobody can say whether the first one is still live, whether an advance was ever discussed, or who was supposed to chase it.
Putting the event date on the deal with an explicit hold status and an expiry turns that into a decision. A hold that has not converted after your agreed window is released deliberately, with a final call to the client, rather than quietly occupying a profitable Saturday for six weeks.
