What Does a Bookkeeper Actually Do? A Small Business Guide

A bookkeeper records and organizes your business's financial activity, makes sure your account balances match your bank and credit card statements, and turns that information into reports you can actually use. This guide explains what a bookkeeper does for a small business, what they usually don't do, and how to tell what kind of help you need.

What does a bookkeeper do for a small business?

A bookkeeper handles the routine work that keeps your financial records accurate. For a Birmingham business with 3–19 employees, that usually means tracking sales and expenses, reconciling bank and credit card accounts, handling payroll, paying bills, invoicing customers and keeping QuickBooks organized.

The exact work depends on your needs and your service agreement. But good bookkeeping is more than data entry. It means reviewing records, catching inconsistencies and asking questions when something doesn't add up, ideally while the details are still fresh.

Categorizing transactions

A bookkeeper records the money that comes into and goes out of your business, then assigns each transaction to the right account. A customer payment, a software subscription, an equipment purchase and an owner withdrawal are all different kinds of activity and shouldn't be recorded the same way.

Getting the categories right makes your reports meaningful. When a transaction is unclear, a good bookkeeper asks for the receipt or more context instead of guessing. That question is much easier to answer the next day than three months later.

Reconciling bank and credit card accounts

Reconciliation means comparing the transactions in your books with the statements from your bank, credit card or other financial accounts. The bookkeeper looks for differences, such as missing transactions, duplicates or wrong amounts, and tracks them down.

Regular reconciliation makes sure your books reflect what actually happened. It also brings questionable charges and recordkeeping gaps to your attention sooner, before they turn into a year-end cleanup project.

Handling payroll

A bookkeeper may collect approved hours, run payroll, record payroll costs and track payroll tax liabilities. Some also handle the federal, state and local payroll tax filings and year-end W-2s and 1099s. Others only record what your payroll provider sends them.

Payroll rules are complex, so ask exactly what's included. At 10 Minute Bookkeeping, payroll support can include employee setup, regular payroll processing, payroll tax filings and year-end reporting.

Preparing financial reports

A bookkeeper prepares regular reports that show how your business is doing. Common reports include:

• Profit and loss statement: revenue, expenses and profit over a period.
• Balance sheet: what your business owns and owes.
• Cash flow: how money moves in and out.
• Accounts receivable and payable: what customers owe you and what you owe vendors.

Reports are only as good as the records behind them, and only as useful as they are current. A P&L you get three weeks after the month ends tells you where you were. That's why every 10 Minute Bookkeeping client gets an Owner Dashboard built from books we update every business day, so you can see revenue, profit, cash, receivables and payables while you can still act on them.

Keeping QuickBooks clean

QuickBooks is software, not a bookkeeper. Someone still has to categorize transactions, match bank feed activity, maintain customer and vendor records, reconcile accounts and make sure the reports are built on consistent information. If the file was never set up properly, QuickBooks setup and consulting can fix the structure underneath it.

If transactions are missing or accounts haven't been reconciled for months, regular bookkeeping isn't enough yet. You'll first need QuickBooks cleanup services to correct past issues and bring your records up to date. Not sure how far behind you are? A QuickBooks Health Assessment will tell you.

What a bookkeeper usually doesn't do

A bookkeeper maintains and organizes your financial records. That's different from a CPA or tax professional, who prepares tax returns, gives tax advice or performs audit work. It's also different from a fractional CFO, who handles forecasting, budgeting and strategic financial guidance.

These roles can overlap depending on the provider's qualifications and your agreement. When you need forecasting and strategy rather than recordkeeping, fractional CFO and controller services cover that higher-level work. For more on the difference, read Fractional CFO vs. Bookkeeper.
