Every fulfillment warehouse has its own policy regarding cut off times for order processing. A good fulfillment company will ship all orders that arrive before 10 a.m. on the same business day. If you miss the 10 a.m. deadline, the order is shipped the next business day. This could impact your customers if a next-day order is placed after 10 a.m. In this case, next-day shipping turns out to be two-day shipping.
