What does to pay at actuals mean with regard to freight?

"To pay at actuals" in freight refers to the payment method where the shipper agrees to pay for transportation costs based on the actual expenses incurred, rather than a pre-negotiated or estimated rate. This means that the final cost will be determined after the shipment has been completed, accounting for variables such as weight, distance, and any additional surcharges. This approach provides transparency but can lead to fluctuating costs based on the specific circumstances of each shipment.
