Financial Accounting: Definition, Principles & Statements

Financial accounting is the structured process of recording, summarizing, and reporting a company’s financial transactions for external users. These users, including investors, lenders, suppliers, and regulatory agencies, rely on standardized accounting financial statements such as the balance sheet, income statement, cash flow statement, and shareholders’ equity statement to understand a company’s financial position and performance. 

In the U.S., these reports must follow Generally Accepted Accounting Principles (GAAP), defined by the Financial Accounting Standards Board. Public companies must also comply with reporting rules set by the Securities and Exchange Commission.

What Is Financial Accounting?

Financial accounting is the process businesses use to track, organize, and report their financial accounts. It provides a clear, standardized view of a company’s performance using historical data, showing what happened during a specific accounting period. 

Because the primary objective of financial accounting is to provide useful information for external decision-makers, it must follow established accounting principles and recognized frameworks such as GAAP and, internationally, the International Financial Reporting Standards.

This introduction to financial accounting also supports essential activities such as loan applications, investment evaluation, tax reporting, audits, and long-term planning. Small businesses benefit from these fundamentals because organized account records help measure profitability, manage cash flow, and guide smarter business operations.

How Financial Accounting Works

The financial accounting process follows several structured steps that ensure accuracy, transparency, and comparability.

Recording Transactions

Every event affecting the business (sales, purchases, payments, expenses) is entered using double-entry accounting. 

Posting to the Ledger

Transactions are transferred to the general ledger, where they are sorted by account type using tools like a chart of accounts.

Adjusting Entries

At the end of each accounting period, entries are adjusted for accruals, depreciation, and deferrals to ensure activity appears in the correct timeframe.

Preparing Financial Statements

Once the ledger is updated, financial accountants prepare standardized reports that summarize a business’s financial activity and position.

The 4 Main Financial Accounting Statements

Financial accounting fundamentals require four core statements, each offering different insights into a company’s financial health.

Balance Sheet

The balance sheet shows a company’s assets, liabilities, and equity at a specific point in time.

Income Statement

The income statement, also known as the profit and loss statement, shows revenue, expenses, and net income. 

Cash Flow Statement

This statement reports cash movement across operating, investing, and financing activities. Businesses rely on it to assess liquidity and long-term stability.

Shareholders’ Equity Statement

This report outlines changes in ownership equity, including share capital, dividends, net income, and retained earnings. 

Financial Accounting Methods

Accrual Method

The accrual basis records revenue when earned and expenses when incurred—regardless of cash movement. It provides a more accurate financial picture and aligns with accepted accounting principles GAAP.

Cash Method

The cash method records revenue and expenses only when cash changes hands. It’s simpler but less precise and is often used by very small businesses.

Financial Accounting Main Principles

These basic accounting principles guide how financial activity is recorded and reported.

Revenue Recognition Principle

Recognize revenue when it is earned, not when cash is collected.

Cost Principle

Assets must be reported at their original cost rather than current value.

Matching Principle

Expenses should be recorded in the same period as the related revenue.

Full Disclosure Principle

All essential information must be included in the financial statements.

Objectivity Principle

Reports must be based on verifiable evidence, not opinion.

Why Financial Accounting Is Important

Financial accounting and reporting play a critical role in business decision-making. Reliable financial statements help owners, lenders, and investors:

• Understand profitability and cash flow
• Evaluate growth opportunities
• Review debt levels and risk
• Support loan applications
• Plan for long-term financial stability

These insights strengthen both finance and accounting operations across an organization.

Who Uses Financial Accounting Reports?

Investors

Investors rely on standardized reports to evaluate performance and future potential.

Auditors

Auditors review financial accounts to ensure compliance and accuracy.

Regulatory Agencies

Agencies, including the Securities and Exchange Commission, require consistent reporting from public companies.

Suppliers

Suppliers review a business’s stability before extending credit.

Banks

Banks use financial statements to assess funding eligibility.

Financial and Managerial Accounting

Financial accounting and managerial accounting serve different purposes in a business, and understanding how they compare helps owners make smarter decisions. While financial accounting focuses on reporting past performance for external users, managerial accounting provides detailed, forward-looking insights for internal planning, budgeting, and daily management.

This comparison shows why both accounting functions matter: financial accounting ensures transparency and compliance, while managerial accounting helps leaders make informed decisions about future operations.

Learning Financial Accounting

Many small business owners build their financial accounting skills through practical tools, short courses, and step-by-step resources with no formal background. Understanding the fundamentals of financial accounting helps you read and interpret financial statements with confidence, apply basic accounting principles correctly, and make better business decisions based on reliable numbers.

You can strengthen your accounting knowledge through:

Building these skills step by step gives you a stronger foundation for managing accounting tasks and improving your internal financial processes.
