The term 'load factoring' is an uncommon terminology used in the invoice factoring business. Freight factoring is the common term used as a general name for invoice factoring contracts in the trucking business.  After a load gets delivered to a client, a trucking company can submit this transaction to a factoring company. The factoring company then approves the invoice, and a first deposit is paid to the trucking company. This initial payment is a percentage of the monetary value of the invoice.   Freight factoring relations follow the general principles of invoice factoring. While approving an invoice, a bill of lading or any ample proof of delivery may also be required.
