A financial controller 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
A financial controller, who may also be referred to as a financial comptroller, usually reports to an organization's chief financial officer (CFO). In smaller organizations that do not have CFOs, the controller might be the top financial officer.
In addition to preparing reports, the controller's responsibilities may also include compliance audits, monitoring internal controls, participating in the budgeting process and analyzing financial data to varying degrees. At some companies, financial controllers are involved in evaluating and selecting technology for use within the finance department or other related departments within the organization.
