Back office work refers to positions within a company that aren't client-facing. The back office is essentially the department that provides support to the front office, or client-facing, positions with their various responsibilities.

Back office skills are administrative-based skills. They include data management and entry; projects and claims processing; market trends and behavior analysis; market research; and finance and accounting responsibilities. Additional back office skills tie to information technology (IT) and human resources.

A back office manager is a professional responsible for overseeing the work performed by individuals in departments such as human resources (HR), accounting, and information technology (IT).
