Antonyms for the term "delivered goods" could be "undelivered items" or "unreceived shipments". If a customer has yet to receive their order from a company, that means the items have not been delivered to them. Sometimes, packages can get lost or delayed during shipping, causing the items to never arrive at their intended destination. These situations would be considered instances of undelivered goods. Similarly, if a business has not yet received the items they ordered from a supplier, they could be referred to as unreceived shipments. These terms are the opposite of delivered goods, which imply that the items have successfully made it to their destination or recipient.
