Is there a way to create an activity like a follow up that occurs X days after the last activity? (ex: a customer doesn't send in their deposit, we want to send a follow up email if the deposit hasn't been received within 5 days). So ideally, if the "deposit received" activity hasn't been checked off within 5 days of when the deposit was invoiced, the salesperson would receive a task to call the customer and ask them why they haven't sent in their deposit.
