OxfordAQA A-Level Accounting: Accounting for organisations with incomplete records (9615) – Revision Notes

These notes condense section 3.2.4, Accounting for organisations with incomplete records, of the OxfordAQA International AS and A-level Accounting (9615) specification, Version 1.2, for International AS exams May/June 2025 onwards and International A-level exams May/June 2026 onwards. This is International A-level only content; the specification places it in the Paper 3: Financial Accounting content. The study guide teaches each idea from the start with longer examples; once these notes stick, attempt the practice questions.

Also useful: the OxfordAQA A-level Accounting hub, the printable checklist, the diagnostic quizzes, the AS control account notes in verification of accounting records and the ratio notes in analysis and evaluation of financial information. All figures below are invented, and all amounts are in US dollars, the currency the specification says question papers use.

3.2.4 at a glance

Specification content	You must be able to
Profit where records are insufficient to prepare income statements	Use statements of affairs to find profit from the change in capital
Techniques to find missing information	Rebuild figures from control/total accounts; cash and bank accounts; gross profit margin, mark up, profit in relation to revenue and inventory turnover; depreciation; disposal profits and losses; and the financial statements
Different recording systems	Weigh the benefits and limitations of single and double entry records

Key terms

• Incomplete records / single entry: records where transactions are not entered twice, so there is no full ledger or trial balance.
• Statement of affairs: sets out every asset and liability on one day; capital is the balancing figure.
• Total account: a control account rebuilt in outline to find a missing figure such as credit sales.
• Balancing figure: the amount needed to make an account or statement agree; in this topic it is usually the figure you are asked for.
• Capital introduced: private funds or property, such as savings or a car, that the owner adds to the business.

Formulae

What	Formula
Capital	Assets − Liabilities
Profit (capital method)	Closing capital − Opening capital + Drawings − Capital introduced
Markup %	Gross profit / Cost of sales × 100
Gross profit margin %	Gross profit / Revenue × 100
Margin from markup	markup / (100 + markup)
Markup from margin	margin / (100 − margin)
Rate of inventory turnover (number of times)	Cost of sales / Average inventory
Rate of inventory turnover (days)	Average inventory / Cost of sales × 365
Profit in relation to revenue %	Profit for year / Revenue × 100
Cost of sales	Opening inventory + Purchases − Closing inventory
Expense for the year	Amount paid − accrual at start + accrual at end + prepayment at start − prepayment at end

Section 3.1.8 of the specification points to the OxfordAQA guide “Formulae for accounting ratios”, which gives the margin, markup, profit in relation to revenue and inventory turnover (days) forms above. Average inventory is normally the average of opening and closing inventories.

Method in steps

Profit from statements of affairs

1. List assets and liabilities at the start; capital = assets − liabilities.
2. Repeat at the end. An overdraft, an accrual and a loan are liabilities; a prepayment is an asset.
3. Change in capital = closing − opening.
4. Add drawings (cash and goods taken). Deduct capital introduced.
5. A negative answer is a loss – say so in words.

Missing figure from a total account

1. Write the opening balance on its normal side (receivables debit, payables credit).
2. Enter every known item on its correct side.
3. Enter the closing balance on the opposite side.
4. Total the heavier side; the gap is the missing figure.

Item	Receivables total account	Payables total account
Receipts / payments by bank	Credit	Debit
Contra	Credit	Debit
Irrecoverable debts	Credit	–
Interest charged on overdue accounts	Debit	–
Sales returns / purchases returns	Credit	Debit
Discounts received	–	Debit

Cash account for missing takings

Opening cash + cash sales = amount banked + payments out of takings + closing cash. Solve for whichever figure is missing.

Inventory and markup

Cost of sales = Revenue × 100 / (100 + markup). Then expected closing inventory = opening + purchases − cost of sales.

Reminder (Hollinmoor Pantry): revenue 57,500 at a markup of 15% gives cost of sales = 57,500 × 100/115 = 50,000 and gross profit 7,500.

Non-current assets

• Carrying amount at disposal = cost − accumulated depreciation on that asset.
• Proceeds − carrying amount = profit (positive) or loss (negative) on disposal.
• Missing purchase = closing cost − (opening cost − cost of asset sold).
• Missing depreciation charge = opening carrying amount − carrying amount disposed + additions − closing carrying amount.

Choosing the technique

You are asked for	Start from
Profit when only asset and liability lists exist	Opening and closing statements of affairs
Credit sales	Trade receivables total account
Credit purchases	Trade payables total account
Takings spent before banking, or drawings from the till	Cash account
The year-end bank figure, or an unrecorded payment	Bank account (summary of statements)
Revenue, cost of sales or gross profit	Markup or gross profit margin
Inventory at either date	Cost of sales first, then rate of inventory turnover
Profit or total expenses	Profit in relation to revenue
Cost of a new asset, depreciation or sale proceeds	Asset at cost and accumulated depreciation figures
Capital at the year end	Opening capital + capital introduced + profit − drawings

Order of work for a complete set of statements

1. Capital at the start, from the opening statement of affairs.
2. Bank and cash accounts for missing receipts, payments or balances.
3. Total accounts for credit sales and credit purchases; then include any cash transactions.
4. Adjust each expense for accruals and prepayments at both dates.
5. Depreciation, then any profit or loss on disposal.
6. Income statement, then statement of financial position. If it balances, your figures are consistent.

Reminder: an accrual at the start of the year was paid this year but belongs to last year, so it is deducted from the amount paid; a prepayment at the start belongs to this year, so it is added.

Must-know distinctions

• Statement of affairs vs statement of financial position: same layout, different source (valuations and lists vs ledger balances).
• Markup vs margin: markup on cost, margin on revenue; markup is always the larger percentage.
• Inventory turnover times vs days: times = cost of sales / average inventory; days inverts it and multiplies by 365.
• Capital introduced vs a loan: capital introduced comes from the owner and is deducted in the capital method; a loan is a liability.
• Credit sales vs revenue: revenue = credit sales + cash sales.

Single entry vs double entry

	Single entry	Double entry
Benefits	Low cost; no bookkeeping training; workable when almost every sale is for cash	Arithmetic proof via the trial balance; regular full statements; an account per customer and supplier; evidence for ratios, budgets and lenders
Limitations	Mistakes and theft can stay hidden; often only a single profit total; an accountant must rebuild the year for a fee	Takes time, skill and often software; omissions and compensating errors still pass the trial balance

Answers

1. 21,300 − 18,500 + 9,600 − 1,700 = 10,700
2. 20 / 120 = 16.67%
3. 20 / 80 = 25%
4. 48,000 × 100/160 = 30,000; gross profit 18,000
5. 90,000 / 12 = 7,500
6. 27,400 + 350 + 3,050 − 2,600 = 28,200
7. 35,850 + 460 + 4,720 − 5,160 = 35,870
8. 5,400 + 300 − 450 = 5,250
9. 7,000 − 6,400 = 600 profit
10. 30,000 + 8,000 − 2,500 − 28,900 = 6,600
11. 75,000 × 8% = 6,000
12. 4,800 / 58,400 × 365 = 30 days

Where marks are usually lost

• Leaving goods taken for own use out of drawings in the capital method.
• Adding capital introduced instead of deducting it.
• Treating a bank overdraft as an asset, or forgetting an accrual, in a statement of affairs.
• Putting the closing balance of a total account on the same side as the opening balance.
• Entering a contra in one total account only, or interest charged on the credit side.
• Applying the markup percentage to revenue as if it were a margin.
• Using closing rather than average inventory in an inventory turnover calculation.
• Not reporting a loss clearly when the capital method gives a negative figure.
• Writing generic points about record keeping in an evaluation instead of linking them to the business described.
