Worked Examples
Example — Sales Ledger Control Account
Opening receivables £12,000
Credit sales £25,000
Cash received £20,000
Discount allowed £1,000

Closing balance calculation:
Debit total:
12,000 + 25,000 = £37,000
Credit total:
20,000 + 1,000 + 500 = £21,500
Closing receivables = £15,500

Proficiency Check
Learn – Unlearn – Relearn Approach
If you believe you have already mastered this topic, attempt the following without referring to notes.
If you are unable to answer confidently, revisit the lesson before proceeding.
Explain why the total of individual receivable accounts should equal the balance in the sales ledger control account.
Credit sales £50,000; cash received £30,000; discount allowed £2,000; opening receivables £15,000. Calculate closing receivables.
A payment from a customer was omitted from the sales ledger control account but recorded in the customer account. How will this affect reconciliation?
Why are control accounts important for internal control?

Solutions to Proficiency Check
Solutions to Proficiency Check
The control account summarises all receivable balances. Totals must match subsidiary ledger totals.
Debit side:
15,000 + 50,000 = £65,000
Credit side:
30,000 + 2,000 = £32,000
Closing receivables = £33,000
Control account balance will be overstated compared with subsidiary ledger.
They allow independent verification of ledger accuracy.
