Incomplete Records for ACCA Financial Accounting
Incomplete records means preparing financial statements when the business has no full double-entry books. You rebuild missing figures from what you do have: opening and closing balances, bank data, and cost-to-sales ratios. Use the accounting equation, ledger accounts, control accounts and mark-up or margin to find each unknown, then prepare the statements.
What this chapter covers
Incomplete records questions give you partial information about a business, often a small trader who never kept a full set of books. You are asked to work out figures such as sales, purchases, drawings or closing inventory, and sometimes to prepare an income statement and statement of financial position.
The chapter is a problem-solving exercise built on things you already know. You use the accounting equation, ledger accounts, receivables and payables control accounts, and the relationship between cost, mark-up, margin and sales. In each question you find the one figure that is missing and calculate it as the balancing figure.
It links to the rest of the FA paper. The final statements follow the same format as in accounts preparation. Control accounts, accruals, prepayments, irrecoverable debts and depreciation all appear again here. In the exam, this material can appear as short objective test questions in Section A and as part of a longer accounts preparation question in Section B.
Incomplete records is worth real effort because it tests whether you understand how double entry fits together, not whether you can memorise a layout. Questions are usually calculation-based, so you either get the number or you do not. The techniques are mechanical once practised, and the same skills (T-accounts, balancing figures, mark-up and margin) support other chapters such as control accounts and accounts preparation. Students who practise it steadily tend to gain marks across several areas of the paper.
Incomplete records: topics in the order to study them
- 1Incomplete Records: Principles and Accounting EquationStart here because the accounting equation (assets − liabilities = capital) lets you find profit when there are no records of income and expenses.
- 2Reconstructing Ledger Accounts and Control AccountsNext, learn to rebuild cash, bank, receivables and payables accounts, because most missing figures come from these balancing figures.
- 3Mark-ups and MarginsThen learn the cost-to-sales relationships, which you need to work out sales or cost of sales when one of them is unknown.
- 4Missing Figures: Inventory Loss, Theft and DrawingsAfter that, combine ledgers and ratios to find lost inventory or drawings, which needs all the earlier skills.
- 5Preparing Financial Statements from Incomplete RecordsFinish with full statements, where you pull every reconstructed figure together into the income statement and statement of financial position.
How to prepare Incomplete records
Treat this chapter as a set of small techniques that you then combine. Practise each one on its own before you attempt full questions.
- Revise the accounting equation and write out the layout of a statement of financial position until you can do it from memory.
- Practise drawing T-accounts for cash, bank, receivables and payables from a list of data. Fill in every known figure first, then find the balancing figure.
- Learn the mark-up and margin formulas: mark-up = profit ÷ cost; margin = profit ÷ sales. Practise converting between them using a table of cost, profit and sales set to 100 or 100 plus the percentage.
- Work through questions on inventory loss or theft. Build the trading account from the known figures, then find the missing amount as the difference between expected and actual inventory.
- Do full statement questions under time pressure, and set out your workings clearly so you can follow your own logic.
- For objective questions, check what the question asks for before you calculate, and use the answer options to test whether your figure is sensible.
Common mistakes in Incomplete records
Mixing up mark-up and margin.
Fix: Write cost, profit and sales in a small table first. Mark-up uses cost as 100%. Margin uses sales as 100%.
Putting figures on the wrong side of a control account.
Fix: Ask whether each item increases or decreases the balance. Sales and opening balances go on the debit side of receivables. Cash and discounts go on the credit side.
Valuing lost inventory at selling price.
Fix: Inventory is valued at cost. Convert using the mark-up or margin before you write the loss.
Forgetting to adjust profit for drawings and capital introduced.
Fix: Use the full formula: profit = closing capital − opening capital + drawings − capital introduced.
Ignoring cash sales when finding total sales.
Fix: Add cash sales to credit sales when the question asks for total sales or when you build the trading account.
Using the wrong opening and closing balances for accruals and prepayments.
Fix: Build the expense account: opening accrual or prepayment, cash paid, and closing figure, then find the charge to the income statement as the balancing figure.
Last-day revision: Incomplete records
- Accounting equation: assets − liabilities = capital.
- Profit = closing capital − opening capital + drawings − capital introduced.
- Every missing figure is a balancing figure in a ledger account.
- Credit sales = closing receivables + cash received + discounts and irrecoverable debts − opening receivables.
- Credit purchases = closing payables + payments − opening payables.
- Mark-up = profit ÷ cost. Margin = profit ÷ sales.
- With a 25% mark-up, cost is 100, profit 25 and sales 125, so margin is 20%.
- Cost of sales = opening inventory + purchases − closing inventory.
- Missing inventory = expected closing inventory − actual closing inventory, valued at cost.
- Drawings are a balancing figure in the cash or bank account if all other items are known.
- Adjust for accruals, prepayments and depreciation before finalising profit.
- Always check that the statement of financial position balances.

Incomplete records: frequently asked questions
What is the difference between mark-up and margin?
Mark-up is profit as a percentage of cost. Margin is profit as a percentage of sales. A 25% mark-up equals a 20% margin, because profit of 25 on cost of 100 is 25 on sales of 125.
How do I find missing sales in incomplete records?
Build a receivables control account with opening balance, closing balance, cash received and any discounts or irrecoverable debts. The balancing figure is credit sales. Add cash sales if the question gives them.
How do I calculate profit if there is no income statement information?
Use the change in capital. Profit = closing capital − opening capital + drawings − capital introduced. Capital is assets minus liabilities at each date.
Do incomplete records questions appear in the objective test section?
Yes, they can. Short questions may ask for one figure such as credit sales, closing inventory or drawings. The technique is the same as in a long question, but you need to work quickly.
