IGCSE Accounting: Accounting Concepts and Modern Practice (Cambridge 0452)

Syllabus edition note. This resource follows the Cambridge IGCSE Accounting 0452 syllabus for exams in 2027, 2028 and 2029 (version 1), first examined in the March 2027 series in India and the June 2027 series elsewhere. If you sit 0452 in November 2026, you sit the 2026 syllabus (version 2), which differs: Paper 1 has 35 multiple-choice marks in 1 hour 15 minutes, not 40 marks in 1 hour 30 minutes; Topic 7 is “Accounting principles and policies”, without 7.2 Ethical considerations or 7.3 Technology and sustainability; 4.4 is “Irrecoverable debts and provision for doubtful debts”; income statements are named instead of statements of profit or loss; three-column running balance accounts are not required; Clubs and societies is 5.4 and Manufacturing accounts 5.5; and 6.3 is “Inter-firm comparison”. For this topic, the 2026 syllabus calls the same ten items accounting principles, and its 7.2 is Accounting policies (the influence of international accounting standards and the objectives of comparability, relevance, reliability and understandability), which the 2027-2029 syllabus removes. If you sit in November 2026, work from the 2026 syllabus on the Cambridge International website.

This guide covers Topic 7 Accounting concepts and modern practice, for Cambridge IGCSE Accounting 0452, syllabus for exams in 2027, 2028 and 2029 (Version 1). It is the last of seven topics. Topics 1 to 6 teach how to record, check, adjust, prepare and analyse accounts; Topic 7 explains the rules of thinking behind those records, the ethical standards expected of the people who keep them, and the part technology plays in keeping them. Sub-topics 7.2 Ethical considerations and 7.3 Technology and sustainability are new in the 2027-2029 syllabus.

Where this fits in 0452

Topic 7 is best learned last, because almost every concept is a reason for a procedure you have already met. Matching is why accrued and prepaid expenses are adjusted, and prudence is why an allowance for irrecoverable debts is kept and inventory is valued at the lower of cost and net realisable value (Topic 4, Accounting Procedures). Business entity is why the owner’s private spending is treated as drawings in a sole trader’s statements (Topic 5, Preparation of Financial Statements). Duality is double entry itself (Topic 2, Sources and Recording of Data), and 7.3 builds on the manual and digital records already met in Topic 2 and on the effect of digital transactions on bank reconciliation and control accounts in Topic 3 (Verification of Accounting Records).

Syllabus coverage

CAMBRIDGE IGCSE ACCOUNTING (0452) — TOPIC 7: ACCOUNTING CONCEPTS AND MODERN PRACTICE

• 7.1 Accounting concepts — the ten concepts listed in the syllabus: business entity, consistency, duality, going concern, historic cost, matching / accruals, materiality, money measurement, prudence and realisation. For each, know what it means and how it is applied in accounting records and statements.
• 7.2 Ethical considerations — the need for an ethical framework in accounting; the fundamental principles of integrity, objectivity, professional competence and due care, confidentiality, and professional behaviour; and the significance to stakeholders and society of applying an ethical framework.
• 7.3 Technology and sustainability — the use of digital applications for all or part of the accounting records; the need to store accounting data safely and sustainably; the risks of not storing it safely and sustainably; the different types of storage system (manual, data storage devices, cloud services, other digital services); and the advantages and disadvantages of each. Note: “Candidates do not need to have knowledge of or access to specific accounting software packages or programs.”

How to approach it

Topic 7 is mostly explanation rather than calculation, but the explanations are only convincing when they are tied to a real entry. For every concept, learn three things together: a one-sentence meaning, a treatment in the records that the concept requires, and what would go wrong in the figures if it were ignored. “Prudence means not overstating profit” earns less than “prudence is why closing inventory that cost $1,100 but can only be sold for a net $600 is valued at $600, reducing profit by $500”. Do the same for 7.2 (principle, meaning, accounting example) and 7.3 (storage type, advantage, disadvantage, risk). Paper 2 questions are based on stimulus material, so practise applying each idea to the business described rather than writing a general definition.

7.1 The ten accounting concepts

Concept	Meaning	Application in the records
Business entity	The business is treated as separate from its owner; only transactions of the business are recorded in its books.	Goods or other assets taken by the owner, and the owner’s private expenses paid by the business, are recorded as drawings, not as business expenses. Capital introduced by the owner is recorded as the owner’s equity in the business.
Consistency	Once a method of treating an item is chosen, it is used in the same way from one period to the next.	A business depreciating vehicles by the reducing balance method keeps using it each year; it should not switch methods without good reason, and never just to change the profit reported. Results for different years can then be compared fairly.
Duality	Every transaction has two aspects, of equal value, which are both recorded.	Every transaction is recorded by a debit entry and a credit entry of the same amount — the basis of double entry, the trial balance and the accounting equation.
Going concern	The business is assumed to be continuing to trade for the foreseeable future, with no intention or need to close.	Non-current assets are shown at cost less accumulated depreciation, spread over their useful lives, rather than at the amount they would fetch if the business closed and sold them now.
Historic cost	Assets are recorded at their original cost, the price actually paid.	Non-current assets are recorded at cost and shown at cost less depreciation; inventory is recorded at cost unless net realisable value is lower. A rise in the market value of land is not recorded.
Matching / accruals	Revenue and the costs used to earn it are recorded in the period they relate to, not when cash is received or paid.	Accrued expenses are added to the expense and shown as other payables; prepaid expenses are deducted and shown as other receivables; accrued income and income received in advance are adjusted in the same way; depreciation spreads a non-current asset’s cost over the years that benefit from it.
Materiality	Items of small value, which would not affect a user’s view of the statements, need not be treated with full precision.	A $25 waste bin expected to last several years is charged as an expense in the year bought, rather than recorded as a non-current asset and depreciated. What counts as material depends on the size of the business.
Money measurement	Only items that can be measured reliably in money are recorded.	The skill of the workforce, staff morale or a good location are not recorded as assets, even though they help the business — one reason statements have limitations (6.5, Analysis and Interpretation).
Prudence	Profits and assets should not be overstated, and losses and liabilities should not be understated; losses are recognised as soon as they are expected, profits only when they are realised.	An allowance for irrecoverable debts is kept against trade receivables; debts that will not be paid are written off; inventory is valued at the lower of cost and net realisable value.
Realisation	Revenue is recognised when goods or services are passed to the customer and the customer accepts liability to pay, not when an order is received or when cash is received.	A credit sale is recorded when the goods are supplied, so an order taken on the last day of the year for goods delivered next year is not revenue of this year.

Two points link the concepts to each other. Matching and prudence both lower reported profit in many adjustments, but for different reasons: matching puts a cost in the right period, while prudence makes sure an expected loss is not ignored. Historic cost and going concern work together: showing a machine at cost less depreciation only makes sense if the business is expected to keep using it.

Worked example: applying the concepts to a draft profit

Nadia Rahman is a sole trader. Her draft profit for the year ended 31 December 2027 is $48,000. On checking, the following are found.

1. Nadia took goods costing $600 for her own use. No entry was made.
2. Nadia’s private electricity bill of $400 was paid by the business and debited to the electricity account.
3. Rent of $5,400 was paid on 1 October 2027 for the six months to 31 March 2028. The full amount was charged as an expense.
4. Wages of $750 owed for the last week of December have not been recorded.
5. Closing inventory was valued at cost, $9,200. It includes a damaged item that cost $1,100; after a repair costing $100 it can be sold for $700.
6. A credit sale of $2,500 was recorded on 31 December 2027 for goods to be delivered on 12 January 2028. The goods were still held and were included in closing inventory at cost.
7. An allowance for irrecoverable debts is kept at 5% of trade receivables. Trade receivables are $12,000 after correcting item 6. The allowance brought forward is $450 and it has not yet been adjusted this year.
8. A waste bin costing $25 was charged to office expenses.

Item  Concept             Working                          Effect on profit $
                          Draft profit for the year                  48,000
1     Business entity     Dr Drawings, Cr Purchases                    +600
2     Business entity     Dr Drawings, Cr Electricity                  +400
3     Matching            Rent for Oct-Dec = 5,400 x 3/6 = 2,700
                          Prepaid 5,400 - 2,700 = 2,700              +2,700
4     Matching/accruals   Wages accrued                                -750
5     Prudence            NRV = 700 - 100 = 600
                          Write down 1,100 - 600 = 500                 -500
6     Realisation         Sale removed from revenue                  -2,500
7     Prudence            New allowance 12,000 x 5% = 600
                          Increase 600 - 450 = 150                     -150
8     Materiality         No adjustment                                   0
                          Corrected profit for the year              47,800

Check: 48,000 + 600 + 400 + 2,700 − 750 − 500 − 2,500 − 150 = 47,800.

The statement of financial position is also affected: inventory $8,700 (9,200 − 500); trade receivables $12,000 less allowance $600 = $11,400; other receivables (rent prepaid) $2,700; other payables (wages accrued) $750; and drawings increase by $1,000 (600 + 400). Items 1 and 2 also add the same $1,000 to profit, so together they leave Nadia’s closing capital unchanged: profit and drawings both rise by $1,000. Nadia also suggests changing the depreciation method for her fixtures this year only, to report a higher profit. The consistency concept says no: the method already in use should continue, so no adjustment is made.

Worked example: going concern and historic cost

A business owns machinery that cost $30,000, with a provision for depreciation of $12,000. If the business closed and sold it now, it would fetch about $10,000.

Machinery at cost                       30,000
Less provision for depreciation        (12,000)
Net book value shown in the SOFP        18,000

Because the business is a going concern and will keep using the machine, it is shown at historic cost less depreciation, $18,000, not at the $10,000 it would fetch in a forced sale today. If the business were about to close, the going concern assumption would no longer apply and the machine would be valued at what it could be sold for, $8,000 lower.

7.2 Ethical considerations

The need for an ethical framework. Accountants and book-keepers prepare information that other people rely on but cannot check for themselves. They can come under pressure — from an owner who wants a higher profit to obtain a loan, or a lower profit to reduce tax — and they see confidential information about customers, employees and the business. An ethical framework sets out, in advance, the standards they are expected to meet, so that they act the same way whoever is asking and whatever the pressure. (Professional accountancy bodies publish codes of ethics built on principles like these — background, not an outcome of 0452.)

Fundamental principle	Meaning	Accounting example
Integrity	Being straightforward and honest in all professional and business relationships.	Not recording sales that did not happen, hiding liabilities or preparing statements the accountant knows to be misleading.
Objectivity	Not allowing bias, a conflict of interest or the influence of others to override professional judgement.	A book-keeper whose relative owes the business money should not be the one deciding whether that debt is irrecoverable; an owner’s pressure should not change the allowance for irrecoverable debts.
Professional competence and due care	Having, and keeping up to date, the knowledge and skill needed for the work, and doing it carefully and thoroughly.	Checking depreciation and accrual calculations before statements are issued; seeking help rather than taking on work beyond one’s knowledge.
Confidentiality	Not disclosing information obtained through work without proper authority, unless there is a legal or professional duty to do so, and not using it for personal advantage.	Not discussing a customer’s overdue account or employees’ wages outside the business; keeping accounting data secure (see 7.3).
Professional behaviour	Complying with relevant laws and regulations and avoiding anything that would discredit the profession.	Keeping records that meet tax law; not helping an owner evade tax; not making false claims about one’s qualifications.

Significance to stakeholders and society. The interested parties in 6.4 (Analysis and Interpretation) all make decisions from accounting information: owners and investors decide whether to invest, banks and lenders whether to lend, suppliers whether to give credit, employees how secure their jobs are, and governments and tax authorities how much tax is due. When an ethical framework is applied, they can trust the figures and decide well. When it is not, the harm spreads beyond the business: loans are made that cannot be repaid, suppliers are not paid, employees can lose their jobs, less tax is collected for public services, and trust in financial information in general is damaged. Applying the framework also protects the business’s own reputation.

Worked example: an ethical dilemma

Sam keeps the books for Nadia’s business in the example above. Nadia is applying for a bank loan and asks Sam to leave out the wages accrual (item 4) and keep the January sale in this year’s revenue (item 6), so that the profit shown is higher.

Corrected profit for the year               47,800
Add back wages accrual left out                750
Add back sale that is not yet realised       2,500
Profit Nadia wants reported                 51,050
Overstatement                                3,250

• Concepts broken: matching / accruals (item 4) and realisation (item 6).
• Principles at stake: integrity, because Sam would knowingly produce misleading figures; objectivity, because Nadia’s pressure would be overriding his judgement; and professional behaviour, because misleading a lender could break the law and discredit the profession.
• Significance: the bank would decide on the loan using a profit $3,250 higher than the true $47,800, and could lend more than the business can repay.
• Advice: Sam should explain to Nadia why the adjustments are required, prepare the statements showing $47,800, and not produce a second, misleading version.

7.3 Technology and sustainability

Digital applications for all or part of the records. A business can keep all its records digitally, or only part of them — for example, a digital sales ledger and cash book but a handwritten petty cash book. Accounting software can record a transaction once and post the double entry, totals, control accounts and trial balance automatically (Topics 2 and 3); spreadsheets, online banking and digital invoices and receipts can hold or supply other parts of the records. The benefits are speed, fewer arithmetic errors and up-to-date information; the drawbacks are cost, training, dependence on the system, and the fact that an input error is carried through automatically. The syllabus does not require knowledge of any particular software package or program.

The need to store accounting data safely. Records are needed to prepare the financial statements, chase trade receivables, pay trade payables, answer questions from tax authorities and lenders, and prove what happened. Many countries’ laws also require business records to be kept for a period of years. Storing data safely means keeping it complete, accurate, available when needed and protected from loss, damage and unauthorised access — which also supports the principle of confidentiality in 7.2.

The need to store accounting data sustainably. Storage has an environmental cost: paper, printing and physical space for manual records; electricity used by computers, devices and remote data storage; and waste when old devices are thrown away. Storing sustainably means, for example, printing only what is needed, not keeping unnecessary duplicate copies, disposing of old devices responsibly after the data on them has been securely removed, and choosing storage the business can keep using and reading for as long as the records are needed.

Risks of not storing data safely and sustainably.

• Loss of data through fire, flood, theft, device failure or accidental deletion, so statements cannot be prepared and amounts owed cannot be proved or collected.
• Unauthorised access, hacking or fraud, so records are changed or confidential information about customers and employees is exposed.
• Penalties for failing to keep required records or to protect personal information.
• Extra cost and time to rebuild lost records.
• Damage to reputation and the trust of customers, lenders and other stakeholders.
• Unnecessary waste and cost from paper, energy and discarded devices.

The four types of storage system.

Storage system	Advantages	Disadvantages
Manual (paper books and files)	Cheap to start; no equipment, power or internet needed; cannot be hacked or corrupted by a software fault.	Bulky and needs physical space; can be destroyed by fire or flood, lost or stolen; slow to search; hard to copy for back-up; uses paper.
Data storage devices (for example external hard drives and USB flash drives)	Large capacity in a small space; fast to access; no internet needed; the business keeps physical control; easy to make back-up copies.	Small devices are easily lost or stolen, exposing data if not protected; devices can fail or be damaged; back-ups must be made regularly and kept somewhere else; devices become outdated and create waste when discarded.
Cloud services (data held on a provider’s remote servers and reached over the internet)	Accessible from any location by authorised users; the provider usually makes back-ups and maintains the equipment; data is safe from a fire or theft at the business premises; capacity can be increased easily.	Needs a reliable internet connection; ongoing charges; the business depends on the provider, so an outage or the provider closing can block access; data is held by a third party, so passwords and access controls matter; the provider’s data centres use electricity continuously.
Other digital services (for example online banking records, digital invoices and receipts, and email)	Records are often created automatically when a transaction takes place; less paper; usually quick to search and download.	Records are spread across several services and can be hard to organise into complete accounts; access depends on each service and its account security; a service may keep records only for a limited time, so the business still needs its own copies.

The syllabus names these four types without listing examples, so the examples above are illustrations. Most businesses combine them — for example, keeping digital records with a copy on a cloud service and a further back-up on a storage device — so that the failure of one does not lose the records.

Common mistakes

Writing a definition of a concept without applying it to the entry in the question. Confusing matching with realisation: matching places costs and revenues in the correct period; realisation decides when revenue is earned at all. Thinking prudence means deliberately understating profit — it means not overstating it, by recognising expected losses. Using business entity to explain drawings but then leaving the owner’s private expense in the statement of profit or loss. Saying materiality allows errors to be ignored — it only allows items of small value to be treated in a simpler way. Treating a fall in market value of a non-current asset as a reason to abandon historic cost or going concern when the business is continuing to use it. In 7.2, naming a principle without saying how it applies to the situation given, or confusing integrity (honesty) with objectivity (freedom from bias and pressure). In 7.3, listing advantages of cloud services without any disadvantage when asked to discuss, and naming software products, which the syllabus does not require.
