Delivered Early This means the order was delivered before its scheduled delivery date. This scenario can happen when florists/shippers make early deliveries due to weather. Delivered Late This can occur due to weather, the recipient was not available, incorrect information was entered on the web/phone or if a customer paid for a Delivery Time Window (DTW).​ Not Received This can occur due to weather, the recipient was not available, incorrect information was entered on the web/phone, or the recipient refused. Flex Delivery During the holidays (i.e., Mother's Day), flex delivery options are available to customers. Flex delivery allows the florist and some vendors a span of days to deliver. Be sure to review the order carefully and keep this in mind when working CSIs. ​
