Evaluate bank reconciliations as a cash control
Assess how reconciliation improves cash records, what it cannot prove and how review and follow-up strengthen the control.
Cambridge International AS & A Level Accounting 9706, 2026–2028 syllabus, Version 2. These lessons cover Topic 1.4 only. Practice is self-checked, not an official Cambridge grade; the separately published 2029 syllabus, timed papers and human subject-teacher review remain outstanding.
Before you begin
- Use double-entry, ledger and trial-balance knowledge from Topic 1.2. Reconciliations compare records with independent or separately maintained evidence; an unexplained difference needs investigation.
Work on paper. Try each question before revealing help, and explain why your method works.
Quick readiness check
Which control most directly improves independence in a bank-reconciliation process?
What you will learn
- Explain the benefits of a bank reconciliation
- Identify its limitations and investigate old reconciling items
- Recommend proportionate cash controls
Benefits depend on regular, independent review
A timely reconciliation can identify unrecorded charges and receipts, posting errors, delayed deposits, duplicated payments and unusual transactions. It helps produce a reliable bank balance and can prompt investigation of cash-flow issues.
Its value increases when someone independent of payment processing prepares or reviews it, signs and dates the work, follows up differences and checks whether old items clear. A monthly reconciliation performed late or without review may leave errors undetected for too long.
When judging the benefits and limitations, consider how often it is prepared, who reviews it, the quality of evidence and whether exceptions are resolved.
A reconciliation is not a complete safeguard
It compares the business cash record with the bank's statement, but both can reflect a genuine payment that was unauthorised. It may not reveal collusion, falsified support, errors in other accounts or cash transactions omitted from both records.
Old cheques, unexplained reconciling entries or repeated round-number differences should be investigated. Use segregation of duties, payment approval, restricted access and independent review alongside reconciliation; no single check guarantees that records are correct.
Pause and explain
A bank statement shows an authorised payment that was never approved internally. Does reconciliation alone prevent it?
Worked example
A small business owner prepares the bank reconciliation but also approves and makes every payment. Give one benefit, one limitation and one improvement.
Show the worked solution
- The reconciliation can identify timing differences and bank items not recorded in the cash book.
- The owner may miss or conceal unauthorised transactions because the same person controls the process.
- Ask a person independent of payment preparation to review the statement, supporting evidence and unresolved items.
Answer The reconciliation can improve accuracy, but concentration of duties weakens independent detection. Add an independent review and investigate exceptions.

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.
A $2,000 cheque has remained unpresented for four months. What should a reviewer do before changing the reconciliation?
Give me a hint
Do not remove it merely because it is old; establish what happened.
Compare my reasoning
- Check the cheque register, payee, date, authorisation and supporting invoice.
- Contact the relevant payee or bank under the business's procedure and confirm whether it cleared or should be stopped.
- Record a correction or reversal only when supported and authorised, then retain evidence of the follow-up.
Investigate the cheque and confirm whether it cleared, is still valid or should be cancelled. Do not remove or reverse it without evidence and approval.
Look for these in your work
- Supporting evidence checked
- Status verified
- Adjustment authorised
A business reconciles quarterly. State one risk of this frequency and recommend a more useful review process.
Give me a hint
Consider how long an error could remain unnoticed and whether exceptions are followed up.
Compare my reasoning
- Cash errors or unauthorised payments may remain undetected for several months.
- Prepare and review reconciliations monthly or at a frequency proportionate to transaction volume and risk.
- Use an independent reviewer, document reconciling items and track old items until resolved.
Quarterly checks can delay detection. Reconcile at least monthly where activity and risk justify it, with independent review and a dated exception log.
Look for these in your work
- Delay consequence stated
- Frequency justified
- Review and follow-up included
The reconciliation agrees after a $1,250 item is entered as 'other'. Evaluate whether this is enough evidence to accept the balance.
Give me a hint
An arithmetical match does not explain an item or establish its classification.
Compare my reasoning
- The $1,250 item needs a description and supporting document.
- Check the source, date, authorisation and correct ledger treatment.
- Do not sign off an unexplained balancing entry; investigate and document the resolution.
No. An unexplained item can hide an error or misstatement even if the totals agree. Trace it to evidence, classify it correctly and document the conclusion before sign-off.
Look for these in your work
- Agreement distinguished from evidence
- Checks named
- Unsupported plug rejected
Common mistakes
- Calling reconciliation preventive when it mainly detects differences after recording
- Assuming a cleared bank transaction was authorised
- Ignoring old reconciling items because the total still agrees
What can you explain now?
Why should old unpresented cheques be investigated?
Compare with the explanation
They may be stale, lost, duplicated or evidence of another error
An item that remains uncleared for a long time needs follow-up.
