Bookkeeper vs accountant vs CPA: what each one does and when you need them

Owners use the three titles loosely, and they mean different things. The difference is not prestige. It is what each one is trained and authorized to do, and that decides who you call when the books are behind, when a notice arrives, and when a lender asks for statements.

What does a bookkeeper do?

A bookkeeper records and organizes the financial transactions of a business so the books stay accurate. The US Bureau of Labor Statistics describes the occupation as recording and classifying financial data and entering transactions into accounting software. The work also covers preparing reports such as balance sheets and income statements, and reconciling discrepancies (BLS Occupational Outlook Handbook, retrieved October 12, 2026).

The typical entry path is some college without a degree, and many workers learn the skills on the job. BLS reported median annual pay of $50,670 for the occupation in May 2025.

The work is steady and repetitive by design. Bank and card reconciliation, income and expense entries, and keeping receivables and payables current happen every month. The output is books you can trust, and that is what everyone else depends on.

What does an accountant do?

An accountant works one level up from the records. BLS describes accountants and auditors as examining financial statements for accuracy and compliance, and computing taxes owed. They also prepare returns, inspect accounting systems for fraud risk, and recommend ways to cut costs (BLS Occupational Outlook Handbook, retrieved October 12, 2026).

A bachelor’s degree, usually in accounting or business, is the typical entry requirement. Median annual pay was $83,680 in May 2025.

The two jobs fit together. The bookkeeper produces the records and the accountant interprets them. If the records are wrong, the interpretation is wrong, which is why a firm that is behind on bookkeeping rarely gets useful advice from the accountant above it.

What makes a CPA different?

A CPA is an accountant with a license. CPAs are licensed by each state’s board of accountancy, and candidates have to pass a national exam and meet other state requirements. All states require 150 semester hours of college coursework, which is 30 more than a typical four-year bachelor’s degree (BLS, retrieved October 12, 2026).

The license brings one practical right. The IRS lists CPAs, enrolled agents and attorneys as the three credential types with unlimited representation rights, covering audits, payment and collection matters, and appeals (IRS credentials page, retrieved October 12, 2026).

BLS adds one more point of difference. Any accountant who files a report with the SEC must be a licensed CPA.

Which one does your business need?

Match the person to the problem, because the titles overlap less than they sound. Four situations cover most owners.

If your books are weeks or months behind, you need a bookkeeper. Catching up the records is the first job, and nothing above it works until it is done.

If you want tax planning or someone to file your returns, you need an accountant, and a CPA or enrolled agent if you also want representation rights. A preparer who holds only a PTIN can prepare the return and cannot represent you on it.

If you have received an IRS notice or an audit letter, you need someone with unlimited representation rights. That means a CPA, an enrolled agent or an attorney.

If a lender, an investor or a regulator wants reviewed statements, ask what the requester will accept. SEC reports are the clearest case where the CPA license is mandatory.

Do you need all three?

Often you need two. A common arrangement is a bookkeeper who keeps the books current each month and a CPA or enrolled agent who reviews them and handles the return and any notices. The bookkeeper is the daily layer and the credentialed professional is the review layer.

The IRS advises using its directory of preparers with credentials and select qualifications (IRS, Choosing a tax professional, retrieved October 12, 2026). It also notes that a preparer outside the directory may still offer quality service, so ask about education and training (IRS credentials page). That check takes a few minutes and is worth doing before you sign an engagement.
