WorkRecords is the method a Labor Supplier uses to deliver their Invoice to their customer.  In the past, other methods used would have been the US Mail, fax, dropping off the invoice in person or email.  Each Labor Supplier uses their current back office process to create the invoice and then uses WorkRecords to deliver or "present" their Invoice to the buyer.  WorkRecords uses the word present to differentiate WorkRecords as the method of delivery versus the Labor Supplier's back office system that is used to generate the Invoice.
