What is bookkeeping?
Bookkeeping is the foundation of accounting. It captures every transaction, classifies it into the right account and keeps the records up to date and reconciled. Accountants then use those records to prepare [financial statements](/glossary/financial-statements), analyse performance and file taxes.
Core bookkeeping tasks
- Recording sales and issuing [invoices](/glossary/invoice)
- Recording bills and purchases
- Tracking payments in and out
- Categorising transactions using a [chart of accounts](/glossary/chart-of-accounts)
- [Bank reconciliation](/glossary/bank-reconciliation)
- Running [payroll](/glossary/payroll) records
- Preparing a [trial balance](/glossary/trial-balance) at month end
Single-entry vs double-entry
Single-entry records each transaction once, like a cash book. It suits very small businesses. [Double-entry bookkeeping](/glossary/double-entry-bookkeeping) records every transaction in at least two accounts (a debit and a credit), which keeps the books balanced and is the standard for most businesses.
Bookkeeping vs accounting
Bookkeeping is recording and organising. Accounting is interpreting, reporting and advising: preparing statements, tax planning and analysing results. In small businesses one person or tool often does both.
Good bookkeeping habits
- Record transactions weekly, not at year end.
- Keep business and personal finances separate.
- Store receipts digitally.
- Reconcile bank accounts monthly.
- Use accounting software to automate data entry and categorisation.
Why it matters
Accurate books mean reliable profit figures, on-time tax filings, fewer penalties, smoother audits and better decisions. Lenders and investors also expect clean records.
