make it possible for us to change the "closing date" for customers.
We sometimes forget to "close" them the day they close, and it would help greatly if we could go back and edit their closing date (date they became a customer.)
I have this issue too. I am trying to edit the "became a customer date" which has auto filled in to the date I imported the list out of Magento.
There is a field called "Close Date" on the Contact record that you can change. Is this what you're referring to?
