Lead times reflect how much time before the delivery date you need to receive an order from a buyer. Buyers will not be able to select a delivery date that is inside of your chosen lead time. The lead time starts calculating from 12:01 am on the day of delivery. So if you need orders at noon the day before delivery, your lead time would be 12 hours. If you need orders at 6 pm two days before delivery, your lead time would be 30 hours. Feel free to reach out to us at firstname.lastname@example.org if you need help calculating what your lead time is.
