What Is Bookkeeping? What is Withholding Tax: Definition, Examples & How It Works

A primer on bookkeeping and how accurate records foster better business decisions

Introduction

Bookkeeping is the day-to-day act of keeping books (i.e., financial records) for a business. Its purpose is to record trustworthy information on revenues, costs, property holdings, debts and equity for owners, managers and advisors to evaluate good financial performance and to fulfill reporting duties while taking informed decisions. Bookkeeping is typically thought of in the realm of small businesses, but its principles are applicable to organizations of all sizes.

What bookkeeping does

At its most basic level, bookkeeping transforms everyday financial activity into organized records. These records are the basis for financial statements, tax returns and management reports. Bookkeeping is the process of answering simple but fundamental questions. What did it spend money on? What is owed and what does the business owe? Answers to these questions—organized and laid out side by side—minimize error, help with planning, and enhance transparency.

Key bookkeeping tasks

Logging Transactions: Sales, purchases, payments and receipts are to be recorded in a uniform manner

Posting transactions: Categorizing entries (such as money going in and out of the business) to the correct accounts, including revenue, rent, utilities, payroll and inventory.

Account reconciliation: Review of the balances recorded with respective bank or credit statement balances to correct errors.

Accounts payable and receivable management: Keeping a record of the bills to be paid, as well as invoices which are owed to the business.

Maintaining supporting documents: Keeping records of all receipts, invoices, contracts and other documentation that support transactions.

Examples of bookkeeping entries

A sale: And its record revenue and method of payment, updating cash or accounts receivable account accordingly.

An acquisition of supplies: Debit the expense and credit your cash account or accounts payable

Payroll: Chart gross wages and tax withholdings, employer tax liabilities, and net pay distributions.

Loan payment: Divide the payment into a principal reduction and an interest expense in the records.

Single-entry vs double-entry bookkeeping

The two most common methods for transaction recording Single-entry bookkeeping is like a checkbook register in that each transaction gets recorded only once. It is easier and might work for the smallest operations with limited transactions. Double-entry accounting, in contrast, captures each transaction in two places: a debit and a credit to different accounts. This way, a system of checks and balances is created that nips errors in the bud while enabling balance sheets to be accurate and acting as a scalable solution for growing operations.

How the bookkeeping process works

Source documents: A source document serves as the beginning of any action (e.g. invoices, receipts, bank statements or payroll reports). These documents need to be collected and preserved for accurate bookkeeping.

Journal entries: Transactions are initially recorded in a chronological log commonly referred to as a journal. All of them, reflect the date, accounts involved, figures and a short narrative.

Posting to ledgers: Each journal entry is posted to the individual account ledgers where similar transactions are grouped, e.g. all rent expenses or all sales revenue.

Reconciliation: Ledger balances are periodically reconciled with external records like bank statements to check for consistency and identify and correct errors.

Trial balance and adjustments: Keeping track of the ledger balances, a trial balance is prepared to verify if total debits are equal to total credits. They fix errors in accruals, prepayments, depreciation and other timing differences.

Financial statements: Accurate ledgers along with adjustments enable the preparation of core financial statements that include the balance sheet, income statement, and cash flow statement.

Often-used bookkeeping reports and how to make sense of them

Income statement: Displays revenues and expenses during a period, showing profit.

Balance sheet: Shows assets, liabilities and equity on a specific date.

Cash flow report: The cash flow of the business as money moves in and out of it; shows liquidity.

These reports are necessary for tracking performance, requesting loans, filing taxes and reporting progress toward business objectives.

Who does bookkeeping and when to seek assistance

The complexity of the finances determines whether bookkeeping is performed by business owners, dedicated bookkeepers, or accounting professionals.
