Routific’s algorithm predicts a precise ETA, but when communicating a delivery window to customers you don’t want to create unrealistic expectations. For example, if your delivery ETA is 2pm and you want to give your customer a one-hour delivery window, 30 minutes before and after the ETA might set their expectation too early.  

Now you can edit Routific’s customer notifications to set a more precise delivery window. So for the 2pm delivery, you can choose 15 minutes earlier than ETA for the earliest arrival, and 60 minutes after the ETA for latest arrival. The customer will get a message to expect their delivery anytime between 1:45pm and 3pm.
