This guide provides shippers with a comprehensive framework for understanding and managing freight in today's increasingly complex supply chain environment. It covers the three primary freight management approaches — in-house, partially outsourced, and fully outsourced — along with the critical role of technology, particularly Transportation Management Systems (TMS). Shippers are guided through identifying standard and hidden freight costs, evaluating technology integration expenses, and building a reliable cost baseline. The guide also helps companies recognize when outsourcing makes sense and how to choose the right logistics partner to drive efficiency, visibility, and bottom-line value.
