Foundations of Accounting
Lesson 1: Introduction to Accounting
Every business, from a small spaza shop in Gaborone to a large mining company like Debswana, needs to keep track of its money. Accounting is the process of identifying, recording, classifying, summarising, and interpreting the financial transactions of a business, so that the information can be communicated to people who need it to make decisions. Accounting is often called "the language of business" because it turns thousands of individual transactions — sales, purchases, wages, rent — into a small number of reports that anyone can read and understand.
Book-keeping is not the same thing as accounting, although the two are closely related. Book-keeping is the day-to-day, routine recording of financial transactions in the books of account (journals and ledgers). Accounting is the wider process that includes book-keeping, but also involves classifying, summarising, analysing, and interpreting the recorded data to produce financial statements and reports that are useful for decision-making.
Book-keeping vs. Accounting
- Book-keeping = recording transactions accurately, day by day (a mechanical, clerical task)
- Accounting = the whole process — recording, classifying, summarising, and interpreting the results so owners, managers, and others can make decisions
- Every accountant needs book-keeping skills, but not every book-keeper needs to interpret the figures
| Stage | What happens | Example |
|---|---|---|
| 1. Identifying | Deciding which events are financial transactions worth recording | A cash sale of P500 is a transaction; a staff meeting is not |
| 2. Recording | Writing the transaction into a book of original entry (journal) | Entering the P500 sale into the Sales Journal or Cash Book |
| 3. Classifying | Grouping similar transactions together in ledger accounts | Posting the sale to the Sales Account in the ledger |
| 4. Summarising | Preparing a trial balance and financial statements from the ledger | Including the sale in total revenue on the Trading Account |
| 5. Interpreting | Analysing the figures to help decision-making | Comparing this year's sales to last year's to judge performance |
Who Needs Accounting Information?
Financial statements are not prepared just to satisfy a legal requirement — they are used by a wide range of people and organisations, both inside and outside the business, each with a different reason for wanting the information.
| User | Why they need accounting information |
|---|---|
| Managers | To plan, control costs, set prices, and make day-to-day and long-term decisions about running the business |
| Government | To assess how much tax (income tax, VAT) the business owes, and to compile national statistics on trade and the economy |
| Investors / Shareholders | To judge whether the business is profitable and worth investing in, and whether to expect a return (dividend) on their money |
| Suppliers | To decide whether the business can be trusted to pay for goods bought on credit, and how much credit to allow |
| Customers | To judge whether the business is stable enough to continue supplying goods or honouring warranties in future |
| Employees | To assess job security, and to support wage negotiations by seeing whether the business can afford pay increases |
The bank is best grouped with investors/lenders. It would examine the financial statements to check whether the business is profitable, whether it already owes a lot of money to others, and whether it generates enough cash to repay the loan with interest.
Notice that different users often want conflicting things from the same set of figures. A manager may prefer to show lower profit to reduce the tax bill, while investors want to see the highest possible profit to justify their investment; the government wants an accurate profit figure to calculate the correct tax, regardless of what either the manager or the investor would prefer to see. This is exactly why accounting concepts and standardised formats (covered later in this lesson) exist — so that the same figures mean the same thing to every user, and cannot easily be manipulated to please one group at the expense of another.
Internal vs. external users
- Internal users (inside the business) — managers and employees, who typically have access to detailed, frequent, internal reports
- External users (outside the business) — government, investors, suppliers, and customers, who normally only see the published, less detailed annual financial statements
- This distinction matters because internal users can request extra information whenever they need it, while external users must rely entirely on what the business chooses (or is legally required) to publish
Branches of Accounting
As businesses have grown larger and more complex, accounting has developed into several specialised branches, each serving a different purpose and, often, a different audience. A small spaza shop may only need simple financial accounting, but a large manufacturer such as a textile factory needs cost accounting to work out exactly what it costs to produce each garment, and management accounting to decide whether a new production line is worth investing in.
| Branch | Focus | Typical user |
|---|---|---|
| Financial accounting | Recording transactions and preparing financial statements (Trading, Profit and Loss Account, Balance Sheet) that summarise the whole business over a period | External users — investors, banks, government, suppliers |
| Cost accounting | Recording and analysing the costs of producing specific goods or services, to help control and reduce costs | Production and operations managers |
| Management accounting | Using financial and cost information to plan, budget, and make internal decisions (e.g. whether to launch a new product) | Internal managers and directors |
Backward-looking vs. forward-looking
- Financial accounting is mostly backward-looking — it reports what has already happened, in a fixed, standardised format required by law and accounting practice
- Cost and management accounting are mostly forward-looking — used for budgeting, planning, and decision-making about the future, and are not required to follow any fixed external format since they are for internal use only
(1) Financial accounting — preparing the Trading and Profit and Loss Account and Balance Sheet for external use by the bank.
(2) Cost accounting — building up the cost per chair from its individual materials, labour, and overhead components.
(3) Management accounting — using cost and revenue projections to decide whether the new machine is a worthwhile investment for the future.
The Accounting Principles and Concepts
For financial statements from different businesses — or from the same business in different years — to be meaningful and comparable, accountants follow an agreed set of rules known as accounting concepts (sometimes called principles or conventions). These concepts are the foundation on which all recording and reporting rests.
| Concept | What it means |
|---|---|
| Money measurement | Only transactions and events that can be expressed in monetary terms are recorded in the accounts. The skill or morale of staff, however valuable, cannot be recorded because it cannot be measured in Pula. |
| Going concern | The business is assumed to continue operating for the foreseeable future, not to be closing down. Assets are therefore valued at their cost to the business, not at what they would fetch in a forced sale. |
| Business entity | The business is treated as a separate entity from its owner. The owner's personal belongings, debts, and bank account are kept completely separate from the business's accounts. |
| Realisation | Revenue (income) is recognised as earned at the point goods or services are sold and legal ownership passes to the customer — not necessarily when the cash is received. |
| Dual aspect | Every transaction has two effects on the accounting equation — a giving effect and a receiving effect — which is why every transaction is recorded on two sides (this is the basis of double entry, covered in Topic 2). |
| Cost concept | Assets are recorded at their original purchase price (historical cost), not at what they might be worth today, because cost is an objective, verifiable figure. |
| Accrual concept | Income and expenses are recorded when they are earned or incurred, not necessarily when the cash is actually received or paid. |
| Matching concept | The expenses incurred in earning revenue in a period are matched against that same period's revenue, so that profit is fairly calculated for that period. |
| Consistency concept | Once a business chooses a particular accounting method (e.g. a depreciation method), it should keep using that same method from year to year, so figures remain comparable. |
| Materiality concept | Only information significant enough to influence the decisions of users needs to be disclosed precisely; very small, insignificant amounts can be treated in the simplest way possible. |
| Prudence (conservatism) | Accountants should not overstate profits or asset values. Anticipate all possible losses, but only record profits once they are reasonably certain (e.g. writing off likely bad debts before they actually happen). |
Exam favourites among the concepts
- Business entity — owner's private house is NOT a business asset
- Going concern — assets valued at cost, not "what if we closed down tomorrow"
- Prudence — "anticipate losses, but never anticipate profits"
- Matching — expenses are matched to the revenue they helped earn, in the same period
- Examiners often give a short scenario and ask you to name the concept being applied or broken — learn the concepts by their one-line definition, not just the list of names
The business entity concept has been broken. School fees are a personal (private) expense of the owner, not a cost of running the business, so they should never be recorded as a business expense — they should instead be treated as drawings (the owner withdrawing value from the business for personal use).
Lesson 2: The Accounting Equation
All double-entry accounting rests on one simple but powerful equation, known as the accounting equation. It expresses the relationship between what a business owns and what it owes.
The accounting equation
Assets = Capital + Liabilities
- Assets — resources owned or controlled by the business that have future economic value (e.g. buildings, vehicles, stock, cash, money owed by debtors)
- Capital — the amount the owner has invested in the business; from the business's point of view, this is what it owes back to the owner
- Liabilities — amounts the business owes to outsiders (e.g. loans, money owed to creditors)
The equation can also be rearranged in two other useful ways, depending on which figure is unknown:
| Form | Used to find |
|---|---|
| Assets = Capital + Liabilities | Total assets, when capital and liabilities are known |
| Capital = Assets − Liabilities | Capital, when total assets and liabilities are known |
| Liabilities = Assets − Capital | Total liabilities, when assets and capital are known |
Both assets and liabilities can be split further, into current and non-current categories, which becomes important when preparing a balance sheet (see Lesson 3):
| Category | Meaning | Examples |
|---|---|---|
| Non-current (fixed) assets | Owned for long-term use in the business, not for resale | Land and buildings, machinery, motor vehicles, fixtures and fittings |
| Current assets | Expected to be turned into cash, sold, or used up within one year | Stock (inventory), debtors, cash at bank, cash in hand |
| Non-current (long-term) liabilities | Debts not due for repayment within one year | Bank loan repayable in five years, mortgage |
| Current liabilities | Debts due for repayment within one year | Creditors, bank overdraft, short-term loan |
Assets = P20,000 + P45,000 = P65,000
Capital = Assets − Liabilities = P65,000 − P15,000 = P50,000
Assets = Capital + Liabilities = P80,000 + P25,000 = P105,000
Effects of Business Transactions on the Accounting Equation
Because of the dual aspect concept, every transaction affects the accounting equation in at least two ways, and the equation must always remain in balance after each transaction. There are four broad types of effect a transaction can have:
No matter how complicated a transaction looks, it always fits into one of these four patterns. The trick to answering an accounting equation question quickly is to ask, in order: "which two things have changed?", "are they both assets, or is one a liability or capital?", and "did each one go up or down?" Once those three questions are answered, the correct row in the table below tells you exactly how the equation should move.
| Type of transaction | Effect on the equation |
|---|---|
| Increases one asset, increases another (or capital/liability) | e.g. buying a vehicle on credit — asset (vehicle) up, liability (creditor) up |
| Increases one asset, decreases another asset | e.g. buying stock for cash — asset (stock) up, asset (cash) down |
| Decreases one asset, decreases a liability or capital | e.g. paying off a creditor from the bank — asset (bank) down, liability (creditor) down |
| Increases/decreases capital directly | e.g. owner introducing more cash (capital up) or withdrawing cash for personal use (capital down, via drawings) |
| Transaction | Assets | = | Capital | + | Liabilities |
|---|---|---|---|---|---|
| Start: introduces P30,000 cash | Cash 30,000 | = | 30,000 | + | 0 |
| Buys stock P8,000 for cash | Cash 22,000; Stock 8,000 | = | 30,000 | + | 0 |
| Buys equipment P10,000 on credit | Cash 22,000; Stock 8,000; Equipment 10,000 | = | 30,000 | + | 10,000 |
| Pays P4,000 off the creditor | Cash 18,000; Stock 8,000; Equipment 10,000 | = | 30,000 | + | 6,000 |
Check: Total assets after all transactions = 18,000 + 8,000 + 10,000 = P36,000. Capital + Liabilities = 30,000 + 6,000 = P36,000. The equation still balances.
Golden rule
- The accounting equation must balance after every single transaction, not just at the end of the year
- If your two sides don't match, you have made a recording error somewhere — go back and check each transaction
Lesson 3: The Balance Sheet
A balance sheet is a financial statement that lists a business's assets, liabilities, and capital at one specific point in time (a "snapshot", not a record of activity over a period). It is simply the accounting equation, set out in a formal, structured layout.
Because it is a snapshot, a balance sheet is always headed "as at" a particular date (e.g. "as at 31 December"), never "for the year ended" — that second phrase is reserved for statements that summarise activity over a period, such as the Trading and Profit and Loss Account covered in Topic 4. A balance sheet prepared the day after another one may look completely different, since every transaction that has happened in between will have changed some of the figures — but the two sides must always still be equal to each other on any given day, for exactly the same reason the accounting equation must always balance.
| Left / top: assets | Right / bottom: capital + liabilities |
|---|---|
| Non-current assets, then current assets | Capital, then non-current liabilities, then current liabilities |
"As at" vs. "for the year ended"
- "As at [date]" — a snapshot statement, describing the position on one single day (the Balance Sheet)
- "For the year/period ended [date]" — a summary of activity throughout a stretch of time (the Trading and Profit and Loss Account, and the Cash Book)
- Using the wrong heading is a common, easily avoidable way to lose marks in an exam — always check which type of statement you are labelling
| Refilwe — Balance Sheet as at 1 January | |
|---|---|
| Non-current assets | |
| Motor vehicle | 25,000 |
| Current assets | |
| Stock | 10,000 |
| Cash at bank | 40,000 |
| Total assets | 75,000 |
| Capital | 60,000 |
| Non-current liabilities | |
| Loan | 15,000 |
| Total capital + liabilities | 75,000 |
Capital was found using: Capital = Assets − Liabilities = 75,000 − 15,000 = P60,000.
Effects of Transactions in a Balance Sheet
As a business trades during the year, its balance sheet keeps changing. Three items in particular have a direct and important effect on capital:
| Item | Meaning | Effect on capital |
|---|---|---|
| Drawings | Cash, goods, or other assets the owner withdraws from the business for personal use | Decreases capital (the owner is taking value out of the business) |
| Expenses | Costs incurred in running the business and earning revenue (e.g. rent, wages, electricity) | Decreases capital (reduces profit, which reduces capital) |
| Revenue | Income earned by the business, mainly from selling goods or services | Increases capital (increases profit, which increases capital) |
How capital changes over a period
Closing Capital = Opening Capital + Additional Capital Introduced + Profit − Drawings
- Profit itself = Total Revenue − Total Expenses for the period
- Drawings are never treated as a business expense — they are a reduction of capital, because of the business entity concept
Profit = Revenue − Expenses = 60,000 − 38,000 = P22,000
Closing Capital = Opening Capital + Profit − Drawings = 50,000 + 22,000 − 8,000 = P64,000
Step 1 — opening capital: Capital = Assets − Liabilities = (5,000 + 3,000) − 1,500 = P6,500
Step 2 — profit for the month: Profit = Revenue − Expenses = 3,200 − 600 = P2,600
Step 3 — closing capital: Closing Capital = 6,500 + 2,600 − 400 = P8,700
Step 4 — closing assets and liabilities: Cash = 5,000 + 3,200 − 600 − 400 = 7,200; Stock = 3,000 + 2,000 = 5,000; Creditor = 1,500 + 2,000 = 3,500
Check: Total assets = 7,200 + 5,000 = P12,200. Capital + Liabilities = 8,700 + 3,500 = P12,200. The balance sheet balances.
Common exam mistakes to avoid
- Do not list drawings as an expense in the Profit and Loss Account — it is a withdrawal against capital
- Do not confuse capital introduced (increases capital directly) with revenue (increases capital only after being included in profit)
- Always double-check that Total Assets = Capital + Total Liabilities before submitting any balance sheet answer
- Fixed/non-current assets are listed in order of permanency (least liquid first); current assets in order of liquidity (least liquid first, cash last) — covered fully in Topic 4
