LTL carriers have scales at their terminals, and those scales are the authority. When a shipment declared at 800 pounds arrives at 1,100 pounds, the carrier issues a supplemental invoice for the weight difference at the actual freight class the weight triggers. That invoice is typically 15 to 25 percent higher than the original quote. The shipper disputes it. The process takes days. And in most cases, the carrier wins because they have the weigh bill.
The prevention is simple: ask the shipper to confirm the actual loaded weight before the carrier arrives. An automated confirmation email that includes this specific request — with a deadline before the carrier booking is finalized — catches the discrepancy before the carrier touches the freight, giving the logistics team time to get a revised quote or update the BOL.
The AI Shipping Coordinator includes weight verification as a standard element of every LTL shipper confirmation — flagging discrepancies automatically and updating the shipment record with confirmed figures.
