What Does a Bookkeeper Actually Do? A Plain-English Guide Most small business owners either don't have a bookkeeper or aren't sure what their bookkeeper is supposed to be doing. Sometimes both. The title is vague enough that it could mean anything from "someone who enters receipts into spreadsheets" to "a certified accountant who handles all financial operations." The job description doesn't help clarify it. Here's what a bookkeeper actually does -- and what they don't. What a Bookkeeper Does: The Five Core Jobs 1. Records Daily Transactions Every time money moves in or out of your business, someone needs to record it. Where it came from. Where it went. What category it belongs in. A bookkeeper enters invoices, receipts, bank deposits, and expenses into accounting software (usually QuickBooks, Xero, or Wave). They categorize them correctly. This is the foundation. If this isn't done accurately and consistently, nothing else in your financial picture is reliable. 2. Manages Accounts Payable (Bills You Owe) Your vendor sends an invoice. Your bookkeeper receives it, logs it in the system, matches it to a purchase order if you have one, and either flags it for approval or pays it on your behalf. They track who you owe money to and when those bills are due. They make sure bills don't fall through the cracks. 3. Manages Accounts Receivable (Money Your Customers Owe You) You invoice a customer for work or products. Your bookkeeper tracks that invoice. They follow up when it's overdue. They record the payment when it arrives. For businesses with lots of customers or invoices, this is crucial. Otherwise money owed to you gets buried. 4. Prepares Monthly Financial Statements At the end of each month, a bookkeeper pulls together the data they've entered and generates your financial statements -- primarily your Profit & Loss statement and your Balance Sheet. You need these to actually know how your business is performing. Most founders have no visibility without a bookkeeper generating them. 5. Handles Payroll (If You Have Employees) If you have employees, a bookkeeper processes payroll, runs deductions (taxes, health insurance, retirement), files payroll tax deposits, and generates required documents for employees and tax authorities. This is legally complex and easy to screw up. A good bookkeeper keeps you compliant. What a Bookkeeper Does NOT Do Bookkeepers do not do tax planning. They record transactions. They don't advise whether to make an S-corp election, whether to take a salary or distributions, or how to structure expenses to minimize your tax liability....
