What Does a Controller Do?

A controller leads an organization’s accounting function and ensures its financial records and reports are reliable. The controller oversees the process of recording transactions, closing the books, and reviewing financial statements. When balances or estimates look unusual, the controller evaluates the supporting information and determines whether the accounting needs correction or further review. This work gives leaders dependable information for assessing performance and helps the organization meet reporting and audit requirements.

What Is a Controller?

A controller is a finance leader responsible for the accuracy and integrity of an organization’s accounting and financial reporting. The role focuses on how transactions are recorded and how financial information is checked, finalized, and communicated. A controller may lead an accounting team or, in a smaller organization, handle some of the work directly.

The controller’s scope depends on the organization. Controllers often oversee accounting operations and may also manage audit or budget functions. Their work supports financial decision-making, but a controller typically focuses on accounting and reporting rather than setting the organization’s overall financial strategy. The U.S. Bureau of Labor Statistics describes controllers as financial managers who direct the preparation of financial reports.

What Are the Main Responsibilities of a Controller?

A central responsibility is overseeing the accounting close. The controller establishes expectations for when transactions should be recorded and what documentation should support them. During month-end or year-end close, the controller reviews reconciliations and unresolved balances to help ensure that transactions appear in the correct reporting period. For example, if an invoice arrives after the close for services already received, the controller evaluates whether an expense should be accrued in that period.

Controllers also review financial statements and internal reports. They check whether reported figures are supported by accounting records and whether significant estimates use reasonable, consistently applied assumptions. If a balance changes unexpectedly, the controller investigates the cause with the accounting team and determines whether it reflects a genuine business change, a timing difference, or an error.

Another responsibility is maintaining effective accounting controls. The controller may set procedures for approving transactions and reviewing reconciliations. They also assess whether access to financial systems is appropriate for employees’ responsibilities. When an external audit takes place, the controller coordinates accounting records and supporting evidence, responds to questions, and helps address identified issues.

Controllers may explain actual results against a budget and clarify what caused a variance. For instance, they might identify that lower payroll expense reflects unfilled positions rather than improved efficiency. This context helps leaders interpret the figures, while decisions about operating plans and priorities generally remain with business leaders.

What Does a Controller Do on a Daily Basis?

A controller’s day often begins by checking the status of accounting deadlines and reviewing issues that could affect reporting. During a close, they may follow up with team members about incomplete reconciliations or examine an unusual balance that needs explanation. They review the records and supporting documents, then decide whether the item is adequately supported or needs correction.

After resolving urgent close issues, the controller may review draft reports and discuss results with managers. If a department’s expenses differ from its budget, the controller helps establish what the records show and whether timing or another factor explains the difference. The controller may then meet with the accounting team to improve a procedure or prepare responses to an audit request. Workload shifts with the reporting calendar, so close periods can be more demanding than the time between them.

What Skills Does a Controller Need?

Strong accounting knowledge helps a controller assess whether transactions and estimates are recorded appropriately. For example, when reviewing an expense accrual, the controller must understand what evidence supports the amount and which reporting period it belongs in. Familiarity with financial statements also helps the controller explain how a change in one account affects the organization’s reported results.

Analytical judgment is useful when a balance differs from expectations. Rather than assuming it is an error, the controller examines the underlying activity and determines whether the difference reflects timing, a changed business condition, or a mistake. Attention to detail supports this review because small recording errors can affect reports used by leaders and external reviewers.

Communication and leadership matter because controllers coordinate work across an accounting team and explain financial information to people outside the function. A controller may need to ask a department manager for documentation, explain why a transaction needs further support, or summarize a variance in plain language. Organization and time management help the team complete recurring close and reporting work on schedule.

How Much Does a Controller Earn?

The latest relevant BLS wage figure available is for financial managers as a broad occupational group, not controllers alone. The BLS reported a median annual wage of $161,700 for financial managers in May 2024. Because this group includes multiple types of financial managers, the figure is a reference point rather than a controller-specific salary. Actual pay varies with factors such as location, industry, organization size, and the responsibilities of the position.

What Is the Career Progression for a Controller?

Many controllers build their experience through accounting positions with increasing responsibility. Early work may involve maintaining records or preparing reconciliations. With experience, an accountant may take on financial reporting, lead parts of the close, or supervise accounting staff before moving into a controller role.

From there, career options depend on the organization and the controller’s interests. A controller may move into a broader corporate or divisional finance leadership role, or pursue a CFO position with wider responsibility for financial strategy. Others deepen their expertise in areas such as technical accounting, financial systems, or multi-entity reporting. Employers’ education and credential preferences vary; the BLS notes that financial managers typically need a bachelor’s degree and several years of experience in a related business or financial occupation.

How Contingent Workforce Management Helps Businesses Hire Controllers

Contingent workforce management services help businesses engage temporary workers and coordinate the administration of those assignments. A company may need an experienced controller to lead a year-end close while a permanent search continues. The work can require someone to review reconciliations and prepare audit support against a fixed reporting deadline. If the company has already selected the worker, hiring them directly and using third-party payrolling can be a lower-cost alternative to a staffing agency.

TCWGlobal helps companies manage contingent controllers through payrolling and workforce support. When a company has chosen a controller for a defined assignment, payrolling can handle employment administration while the worker supports the close or another scoped accounting need. This approach can save money by avoiding staffing-agency sourcing costs when sourcing is not needed, and it can reduce the finance team’s administrative work so it can focus on reporting deadlines.
