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.

What does a sales ledger control account summarise?
What you will learn
- Explain what the sales ledger control account summarises
- Post common sales-ledger totals to the correct side
- Balance an account with debit and credit movements
Summarise customer balances from source books
A sales ledger control account summarises the business's net receivables from customers. It helps organise and review credit transactions using totals from the sales journal, cash book, sales returns journal and relevant general-journal entries.
Credit sales and opening debit balances increase receivables and are debits. Receipts, sales returns, discounts allowed and irrecoverable debts reduce receivables and are credits. Use the underlying source and double-entry effect to choose the side.
Calculate and interpret the closing balance
Balance the account by comparing its debit and credit totals. A closing debit balance normally represents net amounts customers owe; a credit balance can represent net amounts owed back to customers.
The control account is a summary. The syllabus does not require reconciling its balance with the total of individual sales-ledger balances; do not present that as an exam requirement.
Pause and explain
Credit sales are $700. Which side of the sales ledger control account records this increase in receivables?
Worked example
Opening receivables are $500 debit. Credit sales are $2,400; receipts $1,900, returns $80, discounts allowed $20 and irrecoverable debts $40. Find the closing balance.
Show the worked solution
- Debit side = 500 + 2,400 = $2,900.
- Credit movements = 1,900 + 80 + 20 + 40 = $2,040.
- Closing debit = 2,900 − 2,040 = $860.
Answer The sales ledger control account closes with an $860 debit balance, meaning $860 is owed by customers overall.

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.
Opening receivables $420 debit; credit sales $1,600; receipts $1,200; sales returns $70; discounts allowed $30. Calculate the closing control balance.
Give me a hint
Add opening receivables and sales on the debit side; subtract reductions on the credit side.
Compare my reasoning
- Debit total = 420 + 1,600 = $2,020.
- Credit total = 1,200 + 70 + 30 = $1,300.
- Closing balance = 2,020 − 1,300 = $720 debit.
Closing sales ledger control balance: $720 debit.
Look for these in your work
- Sides correct
- Totals correct
- Balance interpreted
Why do receipts, returns and discounts allowed appear on the credit side of the sales ledger control account?
Give me a hint
Each reduces the net amount receivable from customers.
Compare my reasoning
- Receipts settle amounts owed.
- Returns and discounts reduce the customer's balance.
- These reductions are credits in the control account.
They reduce receivables, so they are credited in the sales ledger control account.
Look for these in your work
- All three effects identified
- Common effect stated
- Control side correct
A business writes off a $95 irrecoverable customer debt after the original sale was recorded. State the control-account entry and effect on the closing receivable.
Give me a hint
The amount is no longer expected from the customer, so reduce the control balance.
Compare my reasoning
- Credit the sales ledger control account $95.
- Debit Irrecoverable debts expense $95 in the nominal ledger.
- The closing receivable is $95 lower, all else equal.
Credit Sales Ledger Control $95 and debit Irrecoverable debts expense $95; net receivables fall by $95.
Look for these in your work
- Control entry correct
- Expense entry correct
- Balance effect stated
Common mistakes
- Debiting customer receipts instead of crediting the control account
- Treating a sales return as increasing the amount owed
- Calling a control-account balance the profit for the period
What can you explain now?
Which entry reduces a customer's amount owed in the sales ledger control account?
Compare with the explanation
Credit the control account for a receipt
A receipt reduces the receivable and is credited in the control account.
