Bookkeeper vs. Controller: Key Differences & Why You Need Both

Written by Mary McKeown-Christie | March 10, 2025

As your business grows, so do your financial needs. But who should manage them: a bookkeeper or a controller

Understanding the difference between these roles is essential to making the right hire—and setting your business up for success. Here’s everything you need to know about bookkeepers, controllers, and when to work with each.

What a Bookkeeper is and Primary Responsibilities

 

A bookkeeper is defined as a professional who records financial transactions. They are the foundation of a company’s financial records, managing tasks such as tracking daily expenses, invoicing clients, reconciling bank statements, and maintaining ledgers. Bookkeepers ensure that day-to-day finances are accurate and up to date, providing essential support to both small and large companies.

In terms of company size, the role of a bookkeeper for small businesses is especially critical. In smaller organizations, bookkeepers may handle a broader range of tasks and often work closely with owners to provide a comprehensive view of financial health. Their role allows small businesses to stay organized, meet tax obligations, and ensure cash flow is monitored effectively.

Primary Responsibilities of a Bookkeeper:

 
  • Recording financial transactions and maintaining the general ledger
  • Reconciling bank and credit card statements
  • Managing accounts payable and accounts receivable
  • Invoicing and tracking payments from clients
  • Preparing basic financial reports, such as profit and loss statements

What a Financial Controller is and Primary Responsibilities

 

The financial controller oversees and manages all financial functions. Controllers take a more strategic role in accounting operations, ensuring a company’s financial practices align with broader business goals. They play a key role in financial planning, budgeting, compliance, and preparing for audits. 

Financial controllers work closely with upper management to provide insights into the company’s financial health, often acting as the bridge between bookkeeping and executive leadership.

For medium to large organizations, a financial controller helps shape the financial strategy, manages risks, and ensures financial reporting accuracy. In smaller companies, this role might be less common, but it becomes indispensable as the business scales.

Primary Responsibilities of a Financial Controller:

 
  • Overseeing financial statements and reports
  • Managing budgeting and forecasting processes
  • Ensuring compliance with tax and regulatory requirements
  • Performing financial analysis to aid decision-making
  • Developing and implementing internal financial controls

Controller: Requires advanced financial and accounting expertise, often including a CPA (Certified Public Accountant) qualification or equivalent. Controllers typically have several years of experience and may hold a degree in finance or accounting.
