Bookkeeper vs Accountant vs CPA: Who Does What?

Small business owners often use "bookkeeper," "accountant" and "CPA" interchangeably. They're different roles with different scopes — and knowing the difference helps you buy the right help at the right price.

The short version

• A bookkeeper records and organizes your financial transactions and keeps accounts reconciled.
• An accountant analyzes and interprets financial information, prepares financial statements and adjustments, and may advise on finance decisions.
• A CPA (Certified Public Accountant) is an accountant licensed by a state board of accountancy. CPAs can provide services that are restricted to licensees, such as audits and other attestation, and many specialize in tax.

What a bookkeeper does

Bookkeeping is the daily and monthly work that keeps your records accurate:

• Categorizing bank, card and processor transactions
• Reconciling accounts to statements
• Invoicing customers and applying payments
• Entering bills and preparing payment runs
• Supporting payroll inputs and reconciling payroll journals
• Running the month-end close and producing standard reports

BLS groups bookkeepers with accounting and auditing clerks, a category with a 2025 median pay of $50,670 (BLS, similar occupations table).

What an accountant does

Accountants work at a higher level of analysis:

• Designing the chart of accounts and accounting policies
• Recording complex adjustments: accruals, deferrals, depreciation
• Preparing financial statements and analysis
• Budgeting, forecasting and management reporting
• Advising on financial decisions

Not all accountants are CPAs.

What a CPA does

A CPA holds a state license. Requirements vary by state but generally include education, an exam and experience. CPAs can:

• Perform audits, reviews and other attestation engagements — services generally restricted to licensed CPA firms
• Prepare and file tax returns and represent clients before the IRS
• Provide tax planning and advisory services
• Advise on complex accounting matters

Note that tax preparers don't all need to be CPAs; enrolled agents and attorneys can also represent taxpayers before the IRS. Ask any preparer about their credentials.

How they work together

For most small and mid-sized businesses, the efficient model looks like this:

The bookkeeper keeps the books clean so the CPA spends their (more expensive) time on judgment, not data entry.

Signs you need each

You need a bookkeeper if: your books are behind, uncategorized transactions pile up, invoices go out late or you don't know your cash position.

You need an accountant if: you need management reporting, budgeting, accrual accounting or financial analysis to make decisions.

You need a CPA if: you need tax returns filed, tax planning, an audit or review for lenders or investors, or advice on complex tax matters.

What ExecWing provides

ExecWing provides bookkeeping: categorization, reconciliations, AR/AP, payroll support, month-end close and reports, plus cleanup. Our Senior Bookkeepers handle accrual adjustments you and your CPA approve.

ExecWing does not provide tax preparation or filing, CPA services, audits, reviews or other attestation, or legal advice. We work alongside your CPA and deliver a year-end package for them. See Bookkeeping.

A year in the life: who does what, month by month

The easiest way to see the division of labor is to follow a small business through a calendar year. This example is a 15-person service company with an S corporation election.

Many small businesses do not have a separate accountant. The bookkeeper and CPA split that middle column between them, or a fractional controller covers it.

What "CPA" legally means

CPA is a state license. Requirements are set by each state board of accountancy and generally include education credits, passing the Uniform CPA Examination and an experience requirement, plus ongoing continuing education. NASBA's CPAverify database lets you confirm a license in most states. Only a licensed CPA (or firm) can issue an audit or review report on financial statements.

Enrolled agents (EAs) are another option for tax work. They are federally authorized by the IRS to represent taxpayers, and many small businesses use an EA for tax preparation.

Checklist: what to hand your CPA at year-end

A good bookkeeper prepares this package so your CPA spends time on advice instead of cleanup:

• Year-end balance sheet and profit-and-loss statement
• Bank and credit-card reconciliations for December (or your fiscal year-end)
• A general ledger export
• Fixed-asset additions and disposals, with invoices
• Loan statements showing year-end principal and interest
• Payroll year-end reports
• The 1099 vendor list with W-9s on file
• Notes on anything unusual: owner draws, related-party transactions, large one-time items

Cost of getting the roles wrong

• Using your CPA as a bookkeeper means paying professional rates to categorize transactions, often in a rush at tax time.
• Asking your bookkeeper for tax advice puts them outside their expertise and can leave you exposed.
• Having no reviewer means errors compound. Even a quarterly review by an accountant or CPA catches most problems early.

How to choose: five quick questions

1. Are your books current and reconciled every month? If not, start with a bookkeeper. Nothing else works without clean books.
2. Do you make decisions from monthly reports? If yes and you need analysis, budgets or forecasts, add an accountant or fractional controller.
3. Do you have a filing obligation, a tax notice or an audit request? Use a CPA or enrolled agent.
4. Does a lender, investor or buyer want reviewed or audited financial statements? That requires a CPA firm.
5. Are you spending more than an hour or two a week on any of the above yourself? That time is the clearest signal of where to add help first.

Most growing businesses end up with a dedicated or fractional bookkeeper for the daily and monthly work, plus an outside CPA for tax and annual review. Add an accountant or controller as complexity grows.

The bottom line

Bookkeepers keep records accurate; accountants interpret them; CPAs provide licensed services such as attestation and are frequently your tax professional. Using each for what they do best is usually the most cost-effective approach.
