What is bookkeeping?

Bookkeeping involves recording and classifying all financial transactions in your business. It tracks what your business spends and what it receives.

The name comes from traditional methods using physical books and ledgers. People recorded transactions in daybooks, cashbooks or journals, then transferred them to a ledger.

Today, bookkeeping software has replaced most physical record-keeping, making the process faster and more accurate.

Why do small businesses need bookkeeping?

Accurate bookkeeping provides the financial foundation every successful business needs. Here's why it matters:

• Profitability tracking: Check that you're making more money than you're spending
• Informed decision-making: Access reliable financial information for planning and budgeting
• Cash flow management: Spot potential cash crunches before they happen by tracking payment timing
• Fraud protection: Identify incorrect payments or fraudulent activity that could cost you money
• Tax compliance: Complete accurate tax returns with organized financial records
• Professional relationships: Work more effectively with lenders, investors, and accountants

Can you do your own small business bookkeeping?

Yes, you can absolutely do your own bookkeeping. To do it well, you'll need a good understanding of basic accounting principles, an eye for detail, and the time to keep your records up to date.

For many business owners, time is the biggest challenge. Your expertise is best used running and growing your business, not getting lost in spreadsheets. This is where bookkeeping software can really help. It simplifies and automates many tasks, so you can manage your books confidently without needing to be an expert.

How to do bookkeeping

Effective bookkeeping relies on two core processes that ensure your financial records are accurate and complete. These tasks form the foundation of reliable financial management.

Recording every transaction

Recording transactions captures every financial activity in your business:

• Sales recording: Track all income from point-of-sale systems, invoicing software, or manual entry
• Expense tracking: Document every business-related purchase with proof of purchase for tax deductions
• Automation options: Connect your bank account to bookkeeping software for automatic transaction import
• Manual methods: Use spreadsheets or physical books if you prefer traditional recording

You can record income and expenses at different times depending on whether you do cash or accrual accounting.

Reconciling every transaction

Bank reconciliation involves comparing your bookkeeping records against bank statements to ensure all transactions and balances match.

Common reconciliation items include:

• Bank fees and interest payments
• Deposits in transit
• Outstanding payments
• Timing differences between recording and clearing

Frequency recommendations:

• Daily: Best for high-transaction businesses
• Weekly: Suitable for moderate activity
• Monthly: Minimum for most businesses
• Tax time: Required before filing returns

Regular reconciliation helps you catch errors quickly and prevents work from piling up. You can learn more in our guide on how to do bank reconciliation.

Other small business bookkeeping duties

If you're acting as bookkeeper for a small business, you may also be responsible for:

• accounts receivable: issuing invoices and making sure they're paid
• accounts payable: paying bills on time
• payroll: paying employees

Professional bookkeepers can also help prepare financial reports – such as profit and loss, balance sheet and cash flow reports – and explain how your business is performing.

You should also do your own research to make sure you're up-to-date with key legislation, like Basis Period Reform. For example, the Financial Reporting Council's Periodic Review 2024 was completed in March 2024, introducing changes with an effective date of 1 January 2026.

FAQs on small business bookkeeping

Here are answers to some common questions about small business bookkeeping.

What is the best bookkeeping method for a small business?

Most businesses benefit from the double-entry method. Unlike single-entry, which just tracks income and expenses, double-entry also accounts for assets, liabilities, and equity. This gives you a more complete and accurate picture of your business's financial health. Modern accounting software handles the complexities of double-entry for you.

What are the three golden rules of bookkeeping?

The three golden rules are the foundation of double-entry accounting. They are:

• Debit the receiver, credit the giver.
• Debit what comes in, credit what goes out.
• Debit all expenses and losses, credit all incomes and gains.

Software like Xero applies these rules automatically, so you don't have to think about them.

How much should you pay a bookkeeper per month?

The cost of a bookkeeper in the UK can vary widely. It depends on the number of transactions your business has, the complexity of your accounts, and the level of service you need. Some bookkeepers charge by the hour, while others offer a fixed monthly fee. It's a good idea to get quotes from a few different advisors to find what works for your budget.

How often should I do bookkeeping for my small business?

It's best to keep on top of your books regularly, either daily or weekly. Staying up to date helps you spot issues early, monitor cash flow and make tax time much smoother. Using software with automatic bank feeds can make daily reconciliation a quick and simple task.
