What is a cost center?

A cost center is a bucket inside a company where costs are collected and watched. This cheat sheet covers how to think about one and what to check when you tag travel to it. The detail is further down.

How to think about it

  • It collects costs. A cost center exists to accumulate costs, and its managers get the information to control and manage them.
  • Any level works. A cost center can sit at any level of an organization and doesn't have to report to top management directly.
  • Not only departments. Cost centers can be built around organizational units, operating processes or activities. Functions and projects qualify too.
  • Costs roll up. Costs gathered at lower-level cost centers can be added up to the larger segment above them.

What to check

  • Match your books. Use the same codes your accounting system already uses, so travel lands in the existing cost centers.
  • Put it on the report. Add a project code or cost center to expense reports if finance allocates travel costs by client or department.
  • Don't rely on the card statement. A charge labeled "HTL*3847 DENVER" doesn't say which project or cost center it belongs to.
  • Set fields before bookings begin. Pick consistent cost fields up front and make them part of the booking workflow.

How it works on Engine

Engine reporting supports project, job-code and cost-center context, and company fields like these are used for filtering and reconciliation. Admins can organize travelers into departments, and department managers can manage members within their own department. Travel policies can be assigned to all members, individual members or selected departments.

Questions

What is an example of a cost center?

In the federal accounting standard's example, a veterans health care segment treats hospitals, clinics and nursing homes as responsibility centers, and each can set up its functional units, activities or processes as cost centers.

Is a cost center the same as a department?

Not always. A department can be one, but so can a process, activity, function or project.

What is the difference between a cost center and cost allocation?

A cost center is where costs are collected. Cost allocation is assigning costs to units like these, which federal contract rules call cost objectives.

Why tag travel to a cost center?

So finance can see which unit a hotel or flight belongs to. A card charge on its own doesn't say which project or cost center it's for.
