Small business bookkeeping: how to keep the records useful

Use a business bank account and a separate business card wherever possible. Connect them to your accounting file, then build a chart of accounts that reflects how the company earns money and what it spends to deliver the work. You can add detail later; a long list of nearly identical categories will not make the books clearer.

Decide whether the books will be kept on a cash or accrual basis with your accountant. The choice affects when income and expenses appear, and the method used for bookkeeping must support your reporting and tax requirements.

A deposit may contain several customer sales minus fees and refunds. A loan deposit is not revenue. A payment to a credit card reduces a liability rather than creating another expense. Owner contributions and distributions are different from operating income and costs.

Keep the sales report or invoice, receipt, bank statement, and other evidence that explains the entry. The IRS expects businesses to maintain records that support their income and deductions, but your own team benefits too: a clear record makes a disputed transaction easier to resolve months later.

Once a week, look for new transactions, missing receipts, unpaid invoices, and bills coming due. Resolve descriptions you do not recognize while the purchase is fresh. Match customer payments to the invoices they settle; do not let unmatched cash make good customers look overdue.

If several people spend money, decide who supplies the receipt and who checks the category. A short weekly review prevents dozens of small mysteries from appearing at the end of the quarter.

After the month ends, reconcile every active bank and card account to its statement. Tie processor activity to its settlement reports. Compare payroll expense and liabilities with the payroll provider, and check outstanding invoices, unpaid bills, debt balances, and owner transactions.

Then read the profit and loss statement and balance sheet together. A profit number can look reasonable even when receivables are overstated or a liability is missing. Record adjustments, document open questions, and agree when the month is considered final.

You should be able to see which products or services bring in revenue, whether expenses are increasing, how much customers still owe, and how much cash the company can use. If the chart of accounts cannot answer a question you revisit every month, adjust it deliberately rather than adding categories for every one-off purchase.

Save the month-end package and the underlying records in a place the company controls. Good records are easier to maintain than to reconstruct at tax time.
