1. A lockbox processing system for processing lockbox remittances, the lockbox remittances comprising a check and at least one document associated with the check, the check and at least one document forming a group, the check having a check number associated therewith, the system comprising: a document capture component, the document capture component scanning the at least one document thereby generating a document image, the document capture component further generating a document data record that identifies the at least one document; a first memory coupled to the document capture component and storing the document image and the document data record; a check capture component, the check capture component scanning the check thereby generating a check image, the check capture component further generating a check data record that identifies the check; a second memory coupled to the cheek capture component and storing the check image and the check data record; a header generator for generating a header sheet wherein the header sheet identifies the document image; and a processor coupled to the first memory and the second memory, the processor logically associating the check data record, the document data record, the check image and the document image; wherein the processor further retrieves the check image and the check data record from one or more of the first memory and the second memory and stores the check image and the check data record in one or more of the first memory and the second memory, and wherein the logical association is performed.
