OxfordAQA IGCSE Accounting: Incomplete records and single entry (9215) – Revision Notes

These notes are aligned to the OxfordAQA International GCSE Accounting (9215) specification, version 1.2, for exams from May/June 2026 onwards. They cover the incomplete records content of section 3.4 (topic 4, Preparation of financial statements): the profit of an organisation with insufficient records to prepare income statements, statements of affairs, and the benefits and limitations of different record-keeping systems including single and double entry. Amounts are in dollars. For full explanations read the study guide, then try the practice questions.

Key definitions

Term	Meaning
Incomplete records	Records that are not enough to prepare an income statement and a statement of financial position directly
Single entry	Each transaction recorded once, often only cash and bank movements
Double entry	Each transaction recorded as a debit and a credit, so a trial balance can be taken out
Statement of affairs	A list of assets and liabilities at one date, with capital as the balancing figure
Capital	What the business owes the owner: assets − liabilities
Drawings	Cash or goods the owner takes for personal use; not an expense
Capital introduced	Money or assets the owner puts in; not profit

Formulas to recall

Purpose	Formula
Capital	Assets − liabilities
Profit or loss	Closing capital − opening capital + drawings − capital introduced
Credit sales	Closing receivables + cash received + discount allowed + irrecoverable debts + returns inwards − opening receivables
Credit purchases	Closing payables + cash paid + discount received + returns outwards − opening payables
Missing cash or bank item	Opening balance + receipts − payments = closing balance
Total sales	Credit sales + cash sales

Method: profit from a statement of affairs

1. Draw the opening statement of affairs. Total the assets, deduct liabilities, and write opening capital.
2. Draw the closing statement of affairs in the same way. Write closing capital.
3. Find the change in capital (closing − opening).
4. Add drawings, including goods taken for own use if given.
5. Deduct any capital introduced.
6. Write the answer as profit or loss, and say which.

Worked reminder: a loss

Bright Loom Crafts, a sole trader, has these figures.

Item	1 January	31 December
Equipment	2,600	2,340
Inventory	1,850	1,700
Trade receivables	740	690
Bank	910	420
Cash	90	60
Total assets	6,190	5,210
Trade payables	(1,120)	(1,380)
Capital	5,070	3,830

Capital fell by 1,240. Drawings were 900 and nothing was introduced. Profit = 3,830 − 5,070 + 900 = loss of 340. The owner took out 900, so capital fell even though the loss was smaller than the fall.

Method: finding a missing figure from a bank summary

Pennant Kites banked all takings. For the year: opening bank 1,200; cheques from customers 18,400; cash sales banked 3,100; paid to suppliers 11,900; expenses paid 4,350; closing bank 1,450. Drawings were not recorded.

Drawings = 1,200 + 18,400 + 3,100 − 11,900 − 4,350 − 1,450 = 5,000.

Always check the sign of each balance. A bank overdraft at the start counts as a negative opening balance.

Method: totals accounts

Account	Set out as	Missing figure
Trade receivables	Debit: opening balance and credit sales. Credit: cash received, discount allowed, irrecoverable debts, returns inwards and closing balance	Credit sales
Trade payables	Credit: opening balance and credit purchases. Debit: cash paid, discount received, returns outwards and closing balance	Credit purchases

Once you have credit sales and credit purchases, add cash sales to find total sales. Then use opening and closing inventory to find cost of sales and gross profit. Check expenses for accruals and prepayments before deducting them.

Adjusting values before profit

Any asset or liability changed at the closing date changes closing capital and profit by the same amount.

Late information	Effect on closing capital and profit
Irrecoverable debt written off	Decrease
Provision for doubtful debts created or increased	Decrease
Depreciation not yet recorded	Decrease
Other payable (expense owing)	Decrease
Income due (other receivable)	Increase
Prepaid expense	Increase
Income received in advance	Decrease
Inventory valued lower	Decrease

Worked reminder: an overdraft and a loan

A statement of affairs may include a bank overdraft or a loan. These are liabilities, not negative assets to be ignored. Take a trader with equipment 3,500 and inventory 2,000. The business has a bank overdraft of 600 and trade payables of 900.

Total assets are 5,500. Total liabilities are 600 + 900 = 1,500. Capital is 5,500 − 1,500 = 4,000.

If the same trader also had a loan repayable in three years, you would list it under non-current liabilities, and capital would fall by the loan amount.

Writing a good comment on a system

A comment earns credit when it names a feature, gives its effect and links it to the business. A useful pattern is: feature, so effect, which matters because of the business.

• Single entry has no trial balance, so errors are not flagged, which matters for a trader with many credit customers.
• Double entry produces ledger accounts for each item, so the owner can see which expenses are rising, which matters when the owner wants to control costs.
• Single entry is cheap to keep, which matters for a stall with a handful of daily sales.

Single entry versus double entry

	Single entry	Double entry
Benefits	Cheap, quick and simple; little training; enough for a very small business	Complete ledger accounts; trial balance gives an arithmetic check; statements prepared directly; easier to prove figures
Limitations	No trial balance; errors and fraud are harder to find; profit needs extra calculations; information is limited	More time and cost; needs bookkeeping skill; some errors still not revealed by a trial balance

Points to use in a judgement answer: size of the business, number of credit customers and suppliers, whether a lender or tax authority needs reliable statements, and whether the owner wants to compare expenses year to year.

Must-know distinctions

• Profit from capital gives one figure. An income statement shows how it was earned.
• Drawings are deducted from capital in the statement of financial position but are not an expense in the income statement.
• Capital introduced is an addition to capital, not income.
• A trial balance that agrees does not prove the records are correct.
• A statement of affairs is built from counted and valued items; a statement of financial position is built from the ledger. Their layout can look the same.

Quick self-test

1. Assets are 9,300 and liabilities are 3,900. Find capital.
2. Opening capital is 5,400, closing capital is 7,100, and drawings are 4,000. No capital was introduced. Find profit.
3. Opening capital is 12,000, closing capital is 11,200, drawings are 3,000 and the owner introduced 1,000. Find profit or loss.
4. Name the missing figure found from a trade receivables total account.
5. Opening receivables 1,800; closing receivables 2,100; cash received 14,200; irrecoverable debts 150. Find credit sales.
6. Opening payables 900; closing payables 1,250; paid to suppliers 8,000. Find credit purchases.
7. State two limitations of single entry.
8. State two benefits of double entry.
9. Does an irrecoverable debt discovered after the count raise or lower profit calculated from capital?
10. Is capital introduced added to or deducted from the change in capital when finding profit?

Answers

1. 5,400.
2. 7,100 − 5,400 + 4,000 = profit of 5,700.
3. 11,200 − 12,000 + 3,000 − 1,000 = profit of 1,200.
4. Credit sales.
5. 14,200 + 150 + 2,100 − 1,800 = 14,650.
6. 8,000 + 1,250 − 900 = 8,350.
7. For example: no trial balance to check arithmetic; errors are hard to locate; profit needs extra work; information about expenses and sales is limited.
8. For example: trial balance gives an arithmetic check; income statement and statement of financial position can be prepared directly; records are fuller and easier to prove.
9. Lowers it, because trade receivables and closing capital fall by that amount.
10. Deducted, because it increases capital without being profit.

Where marks are usually lost

• Adding capital introduced instead of deducting it, or deducting drawings instead of adding them back.
• Forgetting to subtract opening capital, so closing capital is quoted as profit.
• Counting trade payables as an asset or leaving out a loan.
• Ignoring late information such as an irrecoverable debt or an accrued expense.
• Leaving out opening trade receivables or payables when finding credit sales or purchases.
• Writing a loss as a profit, or giving no label.
• Using one-word comments on systems, such as “easy” or “accurate”, with no link to the business described.
• Writing that double entry removes all errors.
• Mixing up the statement of affairs with a trial balance.

Frequently asked questions

How do you calculate profit from changes in capital? Profit = closing capital − opening capital + drawings − capital introduced. If the result is negative, it is a loss.

How do you find drawings from a bank summary? Take the opening bank balance, add all receipts and deduct all known payments; the remaining amount needed to reach the closing balance is the missing figure, such as drawings. Treat an opening overdraft as a negative balance.

Are a bank overdraft and a loan shown in a statement of affairs? Yes, as liabilities, not negative assets. A loan repayable in three years would be listed under non-current liabilities, and capital would fall by the loan amount.

What is the difference between a statement of affairs and a statement of financial position? A statement of affairs is built from counted and valued items; a statement of financial position is built from the ledger. Their layout can look the same.

Does late information change the profit from capital? Yes. Any asset or liability changed at the closing date, such as an irrecoverable debt or an accrued expense found after the count, changes closing capital and profit by the same amount.
