Now the customer logs in and drafts it themselves. They fill the House Bill
of Lading or Air Waybill form directly — shipper, consignee, routing,
flights, charges — save it as a draft, edit it as many times as they need,
copy a previous shipment for a repeat booking, and print a draft PDF to
check. When they submit, the record locks, becomes read-only, and a
generated PDF goes to the documentation team.
