But then the client may cancel the job
For this, I would not delete. What I might I want to know later:
- how many times they did this. Could indicate they are too loose with their letting of orders/contracts or just don't take quoting seriously
- if they change their mind again, the info could be easily re-activated if kept
- I could know how many jobs/quotes or $$ potential earnings did not transpire into sales. Might be fodder for investigating sales staff, or whether or not it's limited to this customer
- etc, etc.
Knowledge is power - or so someone apparently once said.
The more we hear silence, the more we begin to think about our value in this universe.
