A comptroller is a management-level position responsible for supervising the quality of accounting and financial reporting of an organization. A financial comptroller is a senior-level executive who acts as the head of accounting, and oversees the preparation of financial reports, such as balance sheets and income statements.
In most Commonwealth countries, the comptroller general, auditor general, or comptroller and auditor general is the external auditor of the budget execution of the government and of government-owned companies. Typically, the independent institution headed by the comptroller general is a member of the International Organization of Supreme Audit Institutions (INTOSAI). In American government, the comptroller is effectively the chief financial officer of a public body.
In business management, the comptroller is closer to a chief audit executive, holding a senior role in internal audit functions. Generally, the title encompasses a variety of responsibilities, from overseeing accounting and monitoring internal controls to countersigning on expenses and commitments.
The word is a variant of "controller". The "cont-" or "count-" part in that word was associated with "compt-", a variant of the verb "count". The term (though criticized by people like Henry Watson Fowler) is probably retained in part because in official titles it was deemed useful to have the title dissociated from the word and concept "control".
A variant explanation is that comptroller evolved in the 15th century through a blend of the French compte ("an account") and the Middle English countreroller (someone who checks a copy of a scroll, from the French contreroule "counter-roll, scroll copy"), thus creating a title for a compteroller who specializes in checking financial ledgers. This etymology explains why the name is often pronounced identically to "controller" despite the distinct spelling. However, comptroller is sometimes pronounced phonetically by those unaware of the word's origins or who wish specifically to avoid confusion with "controller."
A comptroller is a person in the business who oversees accounting and the implementation and monitoring of internal controls, independently from the chief financial officer (or CFO). In the United States, the United Kingdom, Australia, Israel and Canada, a comptroller or financial comptroller is a senior position, reporting to the CFO in companies that have one.
The title of comptroller is used in the Royal Household for various offices, including:
The Comptroller and City Solicitor is one of the High Officers of the City of London Corporation, responsible for provision of all legal services. The post of comptroller dates from 1311, and that of City Solicitor from 1544; the two were amalgamated in 1945.
The title of comptroller is held by various government officials.
In Spain, the word comptroller is translated as "Interventor".
