People usually find this service when something has already gone wrong: a line has stopped, a sample is about to expire, a document has to be somewhere tomorrow that it cannot reach. It is worth understanding how the service works before that day rather than during it.
The other thing being bought is answerability. When a customs officer has a question about a shipment, the shipment cannot answer, so it waits for someone who can. When the question is asked of a courier standing at the counter with the invoice in their hand, it is answered immediately. That is not a marketing claim; it is the entire operational advantage compressed into one sentence.
The economics are less strange than they look. A courier assignment costs roughly what a business-class ticket costs, plus a fee and the ground work at each end. Set against a stopped production line, a grounded aircraft, an expiring clinical sample or a tender that closes at noon, that number stops being the interesting part of the conversation very quickly.
On the Montréal lane this matters more than average, because the schedule and the customs position both reward preparation and punish improvisation. The half hour spent on the description of the goods before departure is the half day you do not spend at the border afterwards.
