Pick any load from last month. Note the date it was unloaded and the date its freight invoice went out. In many businesses the gap runs to days, and none of them were spent working. They went on finding the POD, checking it and typing it again.
Those days land straight on your credit cycle. If a customer pays forty-five days from invoice, a POD that surfaces nine days late makes it fifty-four. Add that up across every load, milestone and timesheet, and the cash tied up in waiting becomes a figure worth showing your finance head.
Every day between the proof and the invoice is credit you extended for nothing.
