Assets = Liabilities + Owner’s EquityThis equation underpins every transaction recorded in the books.
| Adjustment | When required | Journal entry (illustrative) |
|---|---|---|
| Capital vs Revenue expenditure | Purchase of a long‑term asset (capital) vs. repair or maintenance (revenue). | Capital: Dr Plant & Equipment Cr Cash/BankRevenue: Dr Repair & Maintenance Expense Cr Cash/Bank |
| Inventory valuation (trading business) | At year‑end – lower of cost or Net Realisable Value (NRV). | If NRV lower: Dr Cost of Goods Sold Cr Inventory |
| Depreciation (non‑current assets) | Annually, based on chosen method. | Straight‑Line: Dr Depreciation Expense Cr Accumulated Depreciation |
| Disposal of an asset | When an asset is sold or scrapped. | Sale for cash: Dr Cash Cr Plant & Equipment (cost) |
| Accrued expense | Expense incurred but not yet paid at year‑end. | Dr Expense Cr Accrued Expenses (Liability) |
| Pre‑paid expense | Cash paid in advance of receiving the benefit. | Initial payment: Dr Pre‑paid Expense Cr CashYear‑end adjustment (portion used): Dr Expense Cr Pre‑paid Expense |
| Accrued income | Revenue earned but not yet received. | Dr Accrued Income Cr Revenue |
| Pre‑paid (unearned) income | Cash received before the service is performed. | Receipt: Dr Cash Cr Unearned Income (Liability)When earned: Dr Unearned Income Cr Revenue |
| Irrecoverable (bad) debt – specific | When a particular receivable is identified as uncollectible. | Dr Bad Debt Expense Cr Trade Receivables |
| Provision for doubtful debts (estimate) | At year‑end, to reflect expected future bad debts. | Estimate: Dr Bad Debt Expense Cr Provision for Doubtful DebtsWrite‑off specific debt: Dr Provision for Doubtful Debts Cr Trade Receivables |
| Method | Formula (annual charge) | Typical use |
|---|---|---|
| Straight‑Line | (Cost – Residual value) ÷ Useful life | Most common for plant & equipment. |
| Reducing‑Balance (Diminishing Value) | Opening NBV × Depreciation rate | When the asset loses value faster in early years. |
| Revaluation | Adjust to fair value; increase credited to Revaluation Reserve. | Only if permitted by policy and asset has a reliable market value. |
| Aspect | Trading Business | Service Business |
|---|---|---|
| Primary output | Physical goods bought for resale (stock). | Intangible services – expertise, labour, time. |
| Inventory | Maintains stock; valuation required (cost or NRV). | Usually none; may hold small consumables only. |
| Cost of Sales / Cost of Services | COGS = Opening Stock + Purchases – Closing Stock. | Direct service costs (wages, consumables, subcontractor fees). |
| Revenue recognition | When ownership of goods passes to the customer. | When the service is performed or the fee becomes earned. |
| Typical journal entries (selected) |
Purchase of stock: Dr Stock Cr Cash/BankSale of stock: Dr Cash/Bank Cr SalesDr Cost of Sales Cr Stock
|
Provision of service: Dr Cash/Bank Cr Service RevenueDirect service cost (e.g., wages): Dr Service Expense Cr Cash/Bank
|
| Risk profile | Unsold stock, price fluctuations, spoilage, obsolescence. | Non‑payment for services, reputation damage, capacity constraints. |
Two formats are accepted – single‑step (used in the examples below) or multi‑step. The key is to show gross profit (if applicable) and net profit (or loss).

| Ratio | Formula | Interpretation |
|---|---|---|
| Gross Margin % (trading only) | (Gross Profit ÷ Sales) × 100 | Higher % indicates good control of purchase cost. |
| Profit Margin % | (Net Profit ÷ Revenue) × 100 | Shows overall profitability; useful for comparing service and trading firms. |
| Current Ratio | Current Assets ÷ Current Liabilities | Measures short‑term liquidity; >1 is generally satisfactory. |
| Return on Capital (ROE) | Net Profit ÷ Owner’s Capital | Assesses how efficiently the owner’s funds are used. |
| Principle | What it means in practice |
|---|---|
| Entity | The business is separate from its owner(s); personal transactions are not recorded. |
| Duality (Double‑entry) | Every transaction affects at least two accounts – one debit and one credit. |
| Going‑concern | Accounts are prepared assuming the business will continue operating. |
| Historic cost | Assets are recorded at purchase price, not current market value. |
| Prudence (conservatism) | Potential losses are recognised as soon as they are probable; gains only when realised. |
| Matching | Expenses are recorded in the same period as the revenues they help generate. |
| Consistency | Accounting policies should be applied from one period to the next unless a change is justified. |
| Materiality | Only items that could influence decisions need to be recorded in detail. |
| Realisation (Revenue recognition) | Revenue is recorded when the earning process is complete and collection is probable. |
