Controller vs. Comptroller
The controller and comptroller titles refer to the same position, which is the person responsible for all accounting operations of a business. The controller title is more frequently found in for-profit businesses, while the comptroller title is more commonly found in governmental and non-profit organizations.

Key Differences
While comptrollers are more heavily involved in the organization’s internal costs and profits, controllers are more focused on the costs and profits associated with the final stage of the company’s rendered product or service.
Comptrollers generally have a higher ranking in the financial industry than controllers with a higher salary potential.
The words ‘comptroller’ and ‘controller’ are closely related to each other in the field of finance, and refer to finance personnel who conduct activities similar to one another.
Controllers are typically hired to work for private or non-profit businesses, whereas comptrollers are almost always employed within government organizations at the local, state, regional, or federal level.
Comptrollers perform very similar tasks to a controller. A comptroller, however, may hold a higher ranking position in the organization and holds a higher level of responsibility.

The major difference lies in the type of organization each one performs. A comptroller usually works for a government organization, whereas a controller will usually work in a private business.

Controllers look at financial facts and figures after production or completion of services rendered; their main concern is the final bottom line. Comptrollers are different. They need to stay abreast of budgeting and staying within projected figures throughout every stage of business in order to keep constituents happy.
