Basic Accounting Principles Explained Simply

Accounting principles are the shared rules that make a company’s books reliable and comparable. Every transaction is recorded in at least two accounts (double entry); income and expenses are recorded when earned or incurred, not when cash moves (accrual basis); the business is assumed to continue (going concern); methods stay the same from period to period (consistency); and figures are recorded with care (historical cost, prudence and materiality). In Saudi Arabia these ideas are applied through the International Financial Reporting Standards (IFRS) as endorsed by the Saudi Organization for Chartered and Professional Accountants (SOCPA). This guide explains each principle in words, not figures.

What accounting principles are

Accounting principles are the basic assumptions and rules behind every set of books. They answer questions every business faces: when is a sale a sale, what is an asset worth, which costs belong to this month, and what must be disclosed? Without shared answers, two accountants could record the same transaction differently, and two companies could not be compared. Some principles are written into the Conceptual Framework behind IFRS; others are long-standing conventions. Understanding them helps an owner read financial statements, ask the right questions and spot when something is wrong.

Double entry: the base of every record

Every transaction affects at least two accounts, with equal debits and credits. Buying equipment for cash increases one asset (equipment) and decreases another (cash); buying it on credit increases equipment and a liability to the supplier.

This gives the accounting equation: what the business owns (assets) equals what it owes others (liabilities) plus what belongs to the owners (equity). Because every entry keeps the equation in balance, a trial balance whose debits and credits do not agree signals an error. The rules are simple:

Assets and expenses increase with a debit and decrease with a credit.
Liabilities, equity and revenue increase with a credit and decrease with a debit.

Balanced books are not necessarily correct: an entry posted to the wrong account still balances, which is why reconciliations and reviews still matter.

The core principles explained

Accrual basis

Revenue is recorded when it is earned and expenses when they are incurred, whatever the payment date. A service delivered this month but paid next month is revenue of this month; this month’s electricity bill that arrives next month is an expense of this month. The cash basis, which records only cash in and out, is simpler but does not show true performance. Financial statements under IFRS use the accrual basis, except the cash flow statement, which reports cash movements by design.

Going concern

Financial statements assume the business will continue for the foreseeable future and has neither the intention nor the need to close, which is why assets are shown at carrying amounts rather than forced-sale values. When there is material uncertainty about continuing, management must assess and disclose it, and if closure is intended or unavoidable a different basis may be needed.

Consistency

The same policies and methods, such as the depreciation method or the inventory cost formula, are applied from one period to the next so that years can be compared. A change is allowed when a standard requires it or when it gives more reliable and relevant information, and it is explained in the notes.

Matching

Expenses are recognized in the same period as the revenue they help produce. Cost of goods sold is recognized when goods are sold, not bought; a sales commission belongs to the period of the sale; depreciation spreads a machine’s cost over the years it is used. Modern standards express this through their recognition rules rather than as a separate principle, but it remains a useful guide.

Historical cost

Assets are usually recorded at the price paid to acquire them, including the costs of bringing them into use, which can be verified from invoices and contracts. The standards allow or require other bases in some cases, such as fair value for certain financial instruments, and assets must not be carried above the amount recoverable from them.

Prudence

Prudence means caution when making judgments under uncertainty, so that assets and income are not overstated and liabilities and expenses are not understated. It does not mean hidden reserves or deliberately understating profit, which mislead just as much. An allowance for receivables that may not be collected is prudent when it reflects real risk; an inflated one is not.

Materiality

Information is material if omitting, misstating or obscuring it could reasonably be expected to influence the decisions of those who rely on the financial statements. It is judged by size and by nature: a small amount can be material if it involves a related party or a breach of a legal requirement. Materiality lets accountants focus on what matters; it is never a reason to leave known errors uncorrected on purpose.

Other basic concepts

Separate entity: the business and its owners are separate for accounting purposes, so the owner’s personal expenses are not company expenses.
Monetary unit: transactions are recorded in one currency, for most Saudi companies the Saudi riyal.
Accounting period: results are measured over regular periods, usually a financial year.
Full disclosure: the notes give readers what they need to understand the figures.

The chart of accounts

The chart of accounts is the organized list of every account a company uses. It is where the principles become practical: a well-designed chart makes correct classification easy. It is usually grouped into five classes:

Assets: cash and bank, receivables, inventory, prepayments, property and equipment.
Liabilities: payables, accruals, VAT payable, zakat or income tax payable, end-of-service benefits and loans.
Equity: share capital, reserves and retained earnings.
Revenue: sales of goods and services and other income.
Expenses: cost of sales, salaries, rent, utilities, depreciation and finance costs.

Each account has a code, and related accounts sit together so reports can be produced at different levels of detail. Build the chart around the reports you need, from financial statements and VAT and zakat returns to management reports; keep it stable; and use cost centers, such as branch, project or department, rather than a new account for every combination.

How Saudi companies apply IFRS as endorsed by SOCPA

Companies in Saudi Arabia prepare their financial statements under the standards endorsed by SOCPA. Listed companies and other entities required to do so apply full IFRS as endorsed in the Kingdom, and many small and medium-sized entities without public accountability may apply the IFRS for SMEs as endorsed by SOCPA. The endorsement can add requirements or disclosures, so the endorsed version is the one to follow. The Conceptual Framework behind IFRS asks for information that is relevant and faithfully represented, and more useful when comparable, verifiable, timely and understandable; the principles above serve those aims.

Local rules sit alongside the standards. VAT records and invoices, including e-invoicing, follow the rules of the Zakat, Tax and Customs Authority (ZATCA); zakat and income tax returns are prepared from the financial statements with the adjustments ZATCA’s rules require; statutory financial statements are filed with the Ministry of Commerce; and the Companies Law and the company’s own articles set requirements on matters such as audit and reserves.

Putting the principles into practice

Choose the framework: full IFRS or the IFRS for SMEs, as endorsed by SOCPA.
Write your accounting policies for revenue, depreciation, inventory and allowances, and apply them consistently.
Set up the chart of accounts with the cost centers you need.
Record on the accrual basis, posting accruals and prepayments at every month-end.
Reconcile regularly bank, receivables, payables and VAT with source documents.
Close each period: review the trial balance, post depreciation and provisions, and prepare management accounts.
Keep the evidence behind every entry.

Common mistakes

Keeping cash-basis books and converting to accrual only at year-end.
Mixing the owner’s personal spending with company expenses.
Changing depreciation methods or inventory formulas without a reason or a note.
Expensing items that should be capitalized, or capitalizing real expenses.
Ignoring end-of-service benefit accruals until an employee leaves.
A chart of accounts with hundreds of overlapping accounts instead of a clear structure.

Frequently asked questions

What are the basic principles of accounting?

The ones most often taught are double entry, accrual basis, going concern, consistency, matching, historical cost, prudence, materiality, the separate entity concept and full disclosure.

What is the difference between accounting principles and accounting standards?

Principles are the underlying ideas; standards, such as IFRS, are the detailed rules that turn them into requirements for recognition, measurement and disclosure.

Do small businesses in Saudi Arabia need to follow these principles?

Yes. A small business keeps books that support its VAT, zakat or tax obligations, and companies prepare financial statements under the standards endorsed by SOCPA. The scale is smaller; the principles are the same.

Where should a new accountant start?

With double entry and the accounting equation, then the accrual basis and the chart of accounts. After that, the other principles and the standards are much easier to follow.
