Apply entity, duality, going-concern and measurement concepts
Use foundational accounting concepts to explain how business transactions and balances are recorded.
Cambridge IGCSE Accounting 0452 / (9–1) 0985, 2027–2029 Version 1. These lessons follow the 2027–2029 syllabus only; the separate 2026 syllabus update is not yet mapped. Written practice is self-checked, not an official Cambridge grade. Full timed-paper practice and human subject-teacher review remain pending.
Before you begin
- No previous accounting study is assumed. Keep the business, transaction and accounting period in view, and distinguish a resource, a claim and a performance result.
Work on paper. Try each question before revealing help, and explain why your method works.
Quick readiness check
A business buys a vehicle on credit. Which pair of effects illustrates duality?
What you will learn
- Explain business entity, duality and going concern
- Apply historic cost and money measurement
- Identify how concepts affect accounting records
Define the business and its recorded resources
The business-entity concept keeps the business's records separate from the owner's personal transactions. Duality means a transaction has corresponding effects that preserve the accounting equation.
Going concern assumes the business will continue operating for the foreseeable future unless evidence indicates otherwise. Historic cost records an asset using its original transaction cost under the stated accounting treatment; it is not the same as current market value.
Use money measurement carefully
Money measurement records items that can be expressed in monetary terms. It does not mean that non-financial qualities such as staff skill, customer trust or product quality are unimportant.
Use the concept to explain the accounting treatment in context. A loan creates cash and a liability; an owner's personal purchase is not automatically a business transaction.
Pause and explain
A business records staff expertise in money terms even though no reliable monetary amount is available. Which concept limits this recognition?
Worked example
A sole trader pays a personal holiday bill from the business bank account. The business buys equipment for $8,000, although a supplier estimates its current value at $9,500. Explain the entity, duality, historic-cost and money-measurement concepts involved.
Show the worked solution
- Record the private holiday payment as drawings, keeping the owner's private transaction separate from business expenses.
- Record equipment at the transaction cost $8,000 under the historic-cost basis; the estimate is not the amount paid.
- The equipment acquisition affects the asset and the payment/credit balance, preserving duality. Staff skill or reputation may matter but may not be recorded as an exact monetary asset.
Answer Keep the owner's private bill out of business expenses; record equipment at its $8,000 transaction cost, show the corresponding payment/credit effect, and recognise that non-financial qualities may not be measured in the accounts.

Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
The owner pays a personal grocery bill $180 from business cash. State how it should be recorded and which concept it illustrates.
Give me a hint
Keep the owner's private spending separate from business operating expenses.
Compare my reasoning
- Debit Drawings $180 and credit Bank/Cash $180.
- Do not debit business groceries expense unless the purchase was for the business.
- This applies the business-entity concept.
Dr Drawings $180; Cr Bank/Cash $180. The business-entity concept keeps the personal bill separate from business expenses.
Look for these in your work
- Entry correct
- Expense excluded
- Concept named
A business buys equipment for $5,000 cash. Show the accounting equation effects and explain duality.
Give me a hint
Identify the asset acquired and the resource used to pay for it.
Compare my reasoning
- Equipment increases by $5,000.
- Cash decreases by $5,000.
- Total assets remain unchanged before other effects; both sides of the transaction are recorded.
Equipment +$5,000 and cash −$5,000. The paired effects illustrate duality; the transaction cost is $5,000.
Look for these in your work
- Asset added
- Cash reduced
- Paired effects explained
A company's customer reputation and skilled staff are valuable, but no reliable monetary figure is provided. Explain why they may not appear as exact asset amounts.
Give me a hint
Consider which items can be measured and recorded consistently in money.
Compare my reasoning
- The qualities may affect future success and should not be dismissed.
- Money-measurement limits recognition when no reliable monetary amount is available.
- Additional non-financial reporting may help explain them.
The qualities matter, but money measurement may prevent an exact asset amount; suitable non-financial information can supplement the statements.
Look for these in your work
- Value recognised
- Concept applied
- Supplementary evidence suggested
Common mistakes
- Treating the owner and business as one accounting entity
- Using estimated current value when the question specifies historic cost
- Assuming going concern means the business can never fail
- Treating unmeasured non-financial qualities as unimportant
What can you explain now?
What does the business-entity concept keep separate?
Compare with the explanation
The business and the owner's personal transactions
The business's records are prepared separately from the owner's private dealings.

Why can an item be important to a business but absent as a precise monetary amount in its accounts?
If you needed the solution, close it and solve the problem again from a blank page. A correct answer is stronger when you can explain the reason for each step.
