Do You Need a Bookkeeper for a Small Business?

By Bill Stilwell · Last reviewed October 16, 2026

The short answer

Every business needs accurate books from day one, but not every business needs to hire a bookkeeper right away. A bookkeeper records your income and expenses, matches your books to the bank every month, produces simple reports, and keeps your records organized. The Internal Revenue Service (IRS) expects you to keep records that support your tax return, generally for at least 3 years and at least 4 years for employment tax records.

What this means

Bookkeeping is the day-to-day recording of money in and money out. It includes:

Transaction recording: every sale, payment, and expense goes into the books (see 10.5.2 Transaction Recording)
Reconciliation: matching the books to bank and card statements each month (see 10.5.3 Bank Reconciliation)
Reporting: a profit and loss statement and a balance sheet (see 10.5.8 Financial Reports)
Record keeping: receipts, invoices, and statements stored where you can find them (see 10.5.4 Receipt Storage)

A bookkeeper isn’t the same as a tax professional. The bookkeeper keeps the records. The certified public accountant (CPA) or enrolled agent uses them to plan and file taxes (see 6.3.2 CPA or Tax Professional).

IRS Publication 583 says the law generally doesn’t require a specific bookkeeping system, as long as it clearly shows your income and expenses. It also says to keep business and personal money in separate accounts, and to reconcile your business account every month.

Say a lawn care owner does her own books for the first year. She spends Sunday nights sorting receipts and is always three months behind. When she hires a part-time bookkeeper for a monthly fee, her books are current every month and her CPA gets clean numbers at tax time.

Why it matters

You can’t manage what you can’t see. Late books mean you don’t know if you’re making money.
Missing records cost money at tax time. The IRS says your records need to support the income and deductions on your return.
Mixed accounts cause trouble. Personal spending in business books makes taxes harder and can weaken the line between you and your business.
Fraud hides in messy books. Monthly reconciliation catches errors and theft early (see 10.6.8 Separation of Duties).

Who this applies to

Every business. You can do your own books if you have the time, keep up every month, and have simple finances. Consider hiring a bookkeeper when you fall behind, when you run payroll, when you carry inventory, or when your time is worth more doing paid work.

How to do it

Open a separate business bank account and card before you record anything (see 10.4.1 Business Operating Account and 10.4.5 Business Credit Card).
Ask your CPA which bookkeeping software and chart of accounts they want you to use (see 10.5.1 Chart of Accounts).
Decide who does the books: you, a part-time bookkeeper, or a bookkeeping service.
If you hire, ask other owners and your CPA for names. Ask how many clients they have in your industry and which software they use.
Ask how they charge: hourly or a flat monthly fee. Get it in writing.
Give them their own login with limited access. Don’t share your banking password (see 11.7.6 Least Privilege Access).
Agree on a monthly schedule: transactions recorded, accounts reconciled, and reports sent by a set date each month.
Read the monthly reports yourself. Ask about anything that looks wrong.
Set up a records system for receipts and invoices, organized by year and type, as the IRS suggests.
Follow the IRS retention rules: generally 3 years, at least 4 years for employment tax records, and longer in some cases. Ask your CPA for your full list (see 9.8.2 Record Retention Periods).

What proof to keep

Monthly reconciliation reports for every bank and card account
Monthly profit and loss statements and balance sheets
Receipts, invoices, deposit records, and statements
The bookkeeper’s signed agreement

Keep these in your finance folder and in your bookkeeping software, with backups (see 11.8 Business Backups).

Common mistakes

Using one account for personal and business. It’s the fastest way to messy books.
Catching up once a year. Monthly is easier and more accurate.
Giving the bookkeeper full banking access. Give them what they need and nothing more.
Never reading the reports. Hiring a bookkeeper doesn’t mean you stop looking.
Throwing out receipts too soon. Keep records for the time the IRS requires, and longer when your CPA says to.
Picking software your CPA doesn’t use. Ask first to avoid paying to convert later.

When to get help from a pro

CPA: to set up the chart of accounts and check your books before tax season. Ask:

Which software and account setup should my bookkeeper use?
How long should I keep each type of record for my business?

When you interview a bookkeeper, ask:

By what date each month will my books be reconciled and reports sent?
How do you protect my financial data and logins?

Bill’s note

Questions people ask

Can I do my own bookkeeping? Yes, if you keep up every month and your finances are simple. Use software your CPA approves.

How long should I keep business records? The IRS says generally 3 years, at least 4 years for employment tax records, and longer in some situations. Ask your CPA for your exact list.

What’s the difference between a bookkeeper and an accountant? A bookkeeper records transactions and reconciles accounts. An accountant, like a CPA, reviews the numbers, plans taxes, and files returns.

How often should the books be updated? At least monthly, with every bank and card account reconciled.

Audit check

Question: Are the books reconciled to every bank and card account each month, with records kept for the IRS retention periods?
Pass looks like: Separate business accounts, monthly reconciliations, monthly reports the owner has read, organized receipts and invoices, limited bookkeeper access, and a written retention schedule.
Fail looks like: Personal and business money mixed. Books months behind. No reconciliations. Receipts missing or thrown out early. A bookkeeper with full banking access.
Evidence to collect: The last 3 monthly reconciliation reports, recent financial reports, the bookkeeper agreement, and the retention schedule.
