Various embodiments of a system and method for scheduled delivery of shipments with multiple shipment carriers are described. Various embodiments may include a scheduled delivery component configured to receive delivery availability information for multiple shipment carriers. In various embodiments, for each shipment carrier, delivery availability information may specify one or more delivery periods during which that shipment carrier is available to deliver shipments of one or more items to designated locations. This delivery availability information may be utilized to generate a scheduled delivery tool that enables users to select a particular delivery period during which an item is to be delivered. The scheduled delivery tool may provide multiple selectable delivery periods based on the delivery availability information of multiple shipment carriers. The scheduled delivery component may determine that a particular delivery period has been selected and generate a delivery instruction based on such selection.
