How orders, shipments, rates, and labels relate, and which commands move each one along.
Find orders with structured or natural-language search, and let the work queue tell you what is ready to ship.
Take a single order from lookup to a purchased label, with the agent or with direct commands, and confirm the result.
Compare rates, create a shipment, buy, reprint, and void labels, and handle first-purchase owner actions and test labels.
Void a label, fix a shipment, and recover from a wrong purchase without paying twice.
How the agent fills in order and shipment bodies for you, which defaults it applies, and the two rules it will not override.
Ship a batch from the work queue as a human operator, with the checks that keep a batch honest.
