You do not need to become an accountant to read your company’s numbers with confidence, but you do need to understand the accounting basics those numbers are built on. Accounting principles are the agreed rules that decide when revenue is recorded, at what value an asset is carried, and what must appear in the financial statements.
In short, accounting rests on the accounting equation and on six principles that apply to every business: accrual, historical cost, matching, full disclosure, going concern and the business entity principle. Once you understand them, you will understand why your bank balance differs from your net profit, and why personal purchases are not a business expense.
This guide explains accounting basics for beginners and business owners in plain language, with SAR examples from small and medium-sized Saudi businesses. It then shows how accounting software applies these principles automatically, so you do not have to rely on memory or spreadsheets.
Why Business Owners Need to Understand Accounting Principles
Financial decisions are made on numbers, and numbers mean little unless you know the rules used to prepare them. An owner who understands basic accounting principles can ask the right questions and spot an error before it turns into a bad decision.
Consider a common case. A Riyadh store has strong sales during Ramadan, yet the bank balance at month-end is low. Is the store losing money? Not necessarily. Part of the sales may be on credit and not yet collected, and the store may have paid a supplier in advance for next month’s stock. Accounting principles explain the gap.
There are three practical reasons this knowledge matters:
- Reading your statements: you can follow the income statement and balance sheet without depending entirely on someone else’s explanation.
- Dealing with authorities: the Zakat, Tax and Customs Authority (ZATCA) and the Ministry of Commerce work with financial statements prepared under approved accounting standards, not with bank statements.
- Talking to lenders and partners: a bank or investor will read your figures through these same principles, so it is better that you read them first.
The Accounting Equation: Assets = Liabilities + Equity
The accounting equation is the foundation of every set of books: everything the business owns (assets) is financed either by outsiders (liabilities) or by the owner (equity). The two sides must stay equal after every transaction.
Suppose the owner of a restaurant-supplies trading business in Jeddah starts with SAR 200,000 of capital, takes a SAR 100,000 bank loan, and buys SAR 80,000 of stock on credit from a supplier. The table shows the effect of each step on the equation:
| Transaction | Assets | Liabilities | Equity |
|---|---|---|---|
| Owner deposits capital in cash | +200,000 cash | 0 | +200,000 capital |
| Bank loan received | +100,000 cash | +100,000 loan | 0 |
| Stock bought on credit | +80,000 inventory | +80,000 suppliers | 0 |
| Total | 380,000 | 180,000 | 200,000 |
Assets of SAR 380,000 equal liabilities plus equity (180,000 + 200,000). Double-entry bookkeeping keeps this balance by recording a debit and a credit of the same amount for every transaction.
Core Accounting Principles with Saudi Examples
The principles below have the biggest effect on the numbers of small and medium-sized businesses. They underpin the IFRS Standards endorsed in Saudi Arabia by the Saudi Organization for Chartered and Professional Accountants (SOCPA), both full IFRS and the IFRS for SMEs Standard.
Accrual Principle
Under the accrual principle, revenue is recorded when it is earned and expenses are recorded when they are incurred, regardless of when cash is received or paid. This is the main difference between real accounting and simply watching the bank balance.
Example: on 25 March a business sells goods worth SAR 10,000 before tax and issues a tax invoice for SAR 11,500 including 15% VAT, with payment due in April. Under the accrual principle, the SAR 10,000 sale appears in March revenue, and the full amount sits in accounts receivable until it is collected.
Historical Cost Principle
The historical cost principle means assets are recorded at what they actually cost on the day of purchase, not at their current market value. This keeps the figures documented and verifiable against invoices.
Example: a business buys a delivery van for SAR 120,000 before VAT. Even if similar vans cost more a year later, the van stays on the books at cost less accumulated depreciation. The standards allow revaluation or fair value in specific cases, but that is an accounting policy decision under the applicable standard, not a personal estimate.
Matching Principle
The matching principle requires each period to carry the expenses that helped earn its revenue, so the period shows its true profit. Sales should not be recorded in one month and their costs in another.
Example: a store pays its sales staff a 3% commission, settled the following month. If April sales are SAR 300,000, the SAR 9,000 April commission is recorded as an accrued expense in April, even though it is paid in May. By the same logic, the cost of goods sold is recorded in the month the goods were sold, not the month they were bought.
Full Disclosure Principle
The full disclosure principle says the financial statements must include any material information that could change a reader’s decision. This is usually done in the notes to the statements.
Example: if the business is party to a commercial dispute that could end in significant compensation, or has a loan secured against its inventory, these facts must be disclosed even if they do not appear as figures in the income statement. Disclosure protects the business from accusations of hiding information from partners or lenders.
Going Concern Principle
The going concern principle assumes the business will continue operating for the foreseeable future, which is why the cost of long-term assets is spread over the years they are used. If there are serious signs of liquidation, the whole basis of preparation changes.
Example: central kitchen equipment costing SAR 60,000 with an expected useful life of five years is depreciated at SAR 12,000 a year on a straight-line basis. That spread only makes sense because we assume the kitchen will keep operating over those years.
Business Entity Principle
The business entity principle means the business’s accounts are kept completely separate from the owner’s. This applies to a sole establishment for accounting purposes, even though it has no legal personality separate from its owner.
Example: if the owner pays SAR 4,000 from the business account for furniture for his home, it is not a business expense. It is recorded as owner’s drawings in the owner’s current account. Mixing personal and business spending is one of the most common errors that distort profit and cause problems when zakat is calculated.

Basic Accounting Principles in One Table
The table below brings the six principles together with the question each one answers, as a quick reference when you review your numbers:
| Principle | Question It Answers | Quick Example |
|---|---|---|
| Accrual | When do I record revenue and expenses? | A credit sale in March is recorded in March |
| Historical cost | At what value do I record the asset? | A van at its purchase cost of SAR 120,000 |
| Matching | Which expenses belong to this period? | April commission is charged to April |
| Full disclosure | What must the reader know? | A loan secured on inventory |
| Going concern | Do I spread the asset’s cost over years? | Equipment depreciated over 5 years |
| Business entity | Is this a business or an owner expense? | Home furniture is owner’s drawings |

From Principle to Practice: How Accounting Software Applies Them
Good accounting software does not ask you to remember the principles; it applies them to every transaction. In Daysum’s cloud ERP built on Odoo, this works as follows:
- Accrual: when a sales invoice is confirmed, revenue, VAT and the customer balance are recorded immediately, and the customer balance is cleared when payment is registered.
- Matching: when goods are delivered, the cost of goods sold is recorded in the same period, and prepaid expenses can be spread over the months they cover.
- Historical cost and going concern: fixed assets are recorded at purchase cost and depreciation is calculated periodically over the defined useful life.
- Business entity: the chart of accounts separates operating accounts from the owner’s current account, so drawings land in the right place.
- Balance: the system will not accept an unbalanced entry, so the accounting equation holds at every moment. You can go deeper in our article on full control of journal entries.
All these entries flow into the general ledger and build the financial statements without re-entry, as explained in how Odoo and Daysum help manage the general ledger. For VAT-registered businesses, the invoice that generates the entry is the same e-invoice that meets the Fatoora Phase 2 requirements.
Conclusion: Accounting Principles That Protect Your Financial Decisions
Accounting principles are not theory for accountants only; they are what make your numbers honest and comparable. The accounting equation keeps the books in balance, accrual and matching show real profit, historical cost and disclosure make the figures reliable, and going concern and business entity set the frame for every statement.
Start with two simple steps: separate business accounts from your personal spending, and ask your accountant for a monthly accrual-based income statement instead of relying on the bank balance alone.

FAQs About Accounting Principles
For a business owner, the most important accounting principles are accrual, historical cost, matching, full disclosure, going concern and the business entity principle. Together they decide when revenue and expenses are recorded, at what value, and what must appear in the statements. All of them rest on the accounting equation, where assets equal liabilities plus equity.
Many textbooks list the four principles as historical cost, revenue recognition (accrual), matching and full disclosure. They cover how items are measured, recorded and presented. Grouping them into four or seven principles is a teaching convention rather than an official, closed list.
Sources that speak of seven principles usually add the business entity, going concern and consistency (or periodicity) principles to the four above. The order and names vary from one source to another, so focus on the idea each principle protects. In Saudi Arabia, the framework that actually applies is the set of standards endorsed by SOCPA.
The accounting equation states that assets equal liabilities plus equity. In simple terms, everything the business owns was paid for either with borrowed money or with the owner's money. Every transaction changes at least two items so that the equation always stays in balance.
A small business can rely on accounting software that applies the principles automatically, with an accountant or accounting firm reviewing entries and closing periods regularly. The software records routine entries accurately, but judgement calls such as useful lives and provisions need professional input. This combination keeps costs down without sacrificing accurate numbers.
