When deleting a contact associated with a current deal the first thing you will want to do is check to see if there is more than one contact associated with the deal.

If there is more than one contact on the deal, feel free to delete the contact that you will no longer be working with from your database. The deal will remain in its current state with the client that you left in Shaker.

If there is only one contact associated with the deal, we would recommend deleting the deal before deleting the contact. If you do delete the contact first, it's not a big issue. The deal will remain on your "deals board/table" but it will now show as a blank card, as the contact has been deleted.
