What does an accountant do?

An accountant records, reviews, organizes, and explains financial information for an individual, business, nonprofit, or government agency. The role is centered on accuracy, documentation, compliance, and timely reporting.

Typical responsibilities include recording transactions, reconciling bank accounts, managing accounts payable and receivable, preparing journal entries, supporting month-end close, producing financial statements, and assisting with tax preparation or budgeting. Accountants often work with tools such as QuickBooks and Excel, and they must understand standards such as GAAP when preparing or reviewing financial information.

The scope of the job depends on the employer. In a small business, one accountant may handle payroll, invoicing, reconciliations, and tax support. In a larger company, accountants are more likely to specialize in areas such as revenue, fixed assets, cost accounting, tax, audit support, or financial reporting.

Common accountant responsibilities

  • Financial recordkeeping: Posting transactions, maintaining ledgers, and keeping documentation complete and organized.
  • Account reconciliation: Comparing internal records with bank statements, vendor records, or subsidiary ledgers to identify discrepancies.
  • Reporting support: Preparing schedules, reports, and financial statements used by managers, auditors, or tax professionals.
  • Compliance support: Helping the organization follow accounting standards, tax rules, internal policies, and audit requirements.
  • Financial analysis: Explaining changes in expenses, revenue, balances, or cash flow so leaders can make informed decisions.

Accountants work across finance, healthcare, retail, technology, education, government, and many other industries. The role generally requires strong attention to detail, analytical thinking, integrity, and the ability to explain financial information clearly to people who may not have an accounting background. A bachelor's degree in accounting is commonly required, and professionals often build four to seven years of experience before moving into higher-level accounting or management roles.

Some accountants pursue specialized paths such as tax accounting, forensic accounting, auditing, cost analysis, or management accounting. These specialties can influence the type of employer they work for, the credentials they need, and their long-term advancement options.

What does a controller do?

A controller is a senior accounting leader responsible for the accuracy, timeliness, and integrity of an organization's financial reporting. In practical terms, the controller manages the accounting function, supervises accounting staff, designs internal controls, and ensures that financial information is reliable enough for executives, owners, lenders, auditors, and regulators.

Controllers are sometimes described as the company's senior accountant, but the role is broader than technical accounting. A controller must understand how transactions flow through the business, how accounting systems support reporting, and how financial controls reduce risk. The controller also helps translate accounting results into useful business information for the CFO and executive team.

Common controller responsibilities

  • Leading accounting operations: Overseeing general ledger activity, payroll, accounts payable, accounts receivable, and the monthly close process.
  • Preparing and reviewing reports: Managing financial statements, forecasts, budgets, and management reports.
  • Maintaining controls: Establishing internal controls to protect assets, reduce errors, and support compliance with US GAAP and SEC regulations where applicable.
  • Coordinating audits: Working with external auditors, preparing audit schedules, and resolving accounting or documentation issues.
  • Managing teams: Hiring, supervising, training, and evaluating accounting personnel, including remote or distributed teams.
  • Partnering with leadership: Collaborating with the CFO and department heads to improve financial processes, budgeting, forecasting, and reporting quality.

The controller's work is often most visible during month-end close, year-end reporting, audits, system implementations, funding events, acquisitions, and periods of rapid growth. In smaller companies, the controller may handle hands-on accounting work as well as leadership duties. In larger companies, the controller may focus more on oversight, policy, controls, and team management.

Because controllers are accountable for both technical accuracy and operational performance, the role requires strong accounting expertise, leadership judgment, process discipline, and the ability to communicate financial risks and results to senior decision-makers.

Skills an Accountant Needs

  • Attention to Detail: Accountants must record transactions correctly, spot inconsistencies, and maintain clean documentation because small errors can affect reports, taxes, audits, or business decisions.
  • Knowledge of Accounting Principles: A strong understanding of GAAP or other relevant accounting standards is essential for preparing accurate records and supporting compliant reporting.
  • Analytical Skills: Accountants need to interpret financial data, investigate unusual balances, explain variances, and support budgeting or management decisions.
  • Technical Proficiency: Excel, accounting software, enterprise systems, and reporting tools are central to efficient accounting work.
  • Communication Skills: Accountants must be able to explain financial information clearly to clients, managers, auditors, and non-finance colleagues.

Skills a Controller Needs

  • Leadership: Controllers manage accounting teams, assign work, review output, set expectations, and keep reporting deadlines on track.
  • Strategic Thinking: They develop policies, improve financial processes, support long-term planning, and connect accounting results to business priorities.
  • Advanced Financial Knowledge: Controllers need expertise in budgeting, forecasting, regulatory compliance, internal controls, audits, and financial reporting.
  • Problem-Solving: They must resolve complex accounting issues, system problems, control gaps, and reporting risks before those issues affect leadership decisions.
  • Communication and Presentation: Controllers regularly explain results, risks, forecasts, and recommendations to executives, board members, lenders, auditors, and department leaders.

The practical difference is this: an accountant proves value by producing accurate financial work. A controller proves value by ensuring the entire accounting function produces accurate, timely, useful, and controlled financial information.
