Bill of lading
The shipping document that proves what was picked up and delivered, and usually starts the payment clock.
A bill of lading, or BOL, is the document issued when freight is picked up. It describes the shipment, names the shipper, carrier and consignee, and serves as a receipt and as evidence of the contract of carriage. When the receiver signs it on delivery, it becomes proof of delivery.
For cash flow, the signed BOL is the document most brokers require before they will process an invoice. A missing signature, an illegible copy or a BOL that was never returned by the driver puts the invoice at the back of the line. Taking a clear photo of the signed document at the dock is one of the simplest habits that shortens a carrier's float.
