Logistics is built on communication, yet the terminology often feels like its own language.
From 3PL vs 4PL to OTIF, deadhead, accessorials, and every acronym in between, “logistics lingo” shows up everywhere: quotes, carrier conversations, invoices, and the fine print that impacts cost and service. When the terms are unclear, decisions get harder and mistakes get more expensive.
In this episode of Logistics Unplugged, host Brian Blalock is joined by Holt Parsons and Jon Shoen for a fast paced, approachable breakdown of the terms that power day to day shipping. The conversation keeps it light, but the takeaways are practical: what the words mean, why they matter, and how to use them to work more effectively with carriers and logistics partners.
