Reconciliations Interview Questions & Answers

Q: What is a reconciliation in accounting?

A reconciliation compares two independent records of the same thing to confirm they agree, and investigates/corrects any differences. In AP/AR it ensures sub-ledgers tie to the general ledger, ledgers tie to supplier/customer statements, and recorded cash ties to the bank. It's a core control that catches errors, omissions, and fraud.

Q: What is a bank reconciliation?

A bank reconciliation compares the company's cash ledger to the bank statement, explaining differences such as outstanding checks, deposits in transit, bank fees, interest, and errors. Reconciling to an agreed balance confirms recorded cash is accurate and surfaces unrecorded items or fraud like unauthorized withdrawals.

Q: What is a sub-ledger to general-ledger reconciliation?

It confirms that the detailed sub-ledger (e.g., the AP or AR aging, which lists every open invoice) totals to the single control-account balance in the general ledger. Differences arise from journals posted directly to the control account, timing, or posting errors, and must be investigated so the detail supports the GL.

Q: What are reconciling items and how are they classified?

Reconciling items are the differences that explain a gap between two records. They're classified as timing differences (will self-correct, e.g., deposits in transit), permanent differences needing an adjusting entry (e.g., bank fees), and errors requiring correction. Documenting each with an action and owner is key to a clean reconciliation.

Q: How do you reconcile a supplier statement to the AP ledger?

Compare the supplier's statement (what they say you owe) to your AP ledger for that vendor, line by line. Identify missing invoices to post, credits not yet applied, duplicate entries, disputed items, and timing differences (in-transit payments). Resolve each so the balances agree, preventing missed liabilities or over/underpayment.

Q: What is the GR/IR reconciliation and why does it matter?

The GR/IR (goods-received/invoice-received) reconciliation analyzes the clearing account that holds the gap between receiving goods and receiving invoices. Open balances mean goods received but not invoiced (accrue) or invoiced but not received (investigate). Clearing it keeps liabilities accurate and prevents old, unexplained balances from accumulating.

Q: How do you reconcile intercompany AP/AR balances?

Intercompany reconciliation matches what one group entity owes (AP) against what the counterparty entity is owed (AR); they should mirror each other. Differences from timing, FX, disputes, or missed postings are identified and resolved before consolidation so intercompany balances eliminate cleanly and don't distort group results.

Q: What is the account reconciliation process at month-end close?

At close, balance-sheet accounts (AP, AR, bank, GR/IR, accruals, prepayments) are reconciled: the ending balance is substantiated with supporting detail, reconciling items are documented with owners and aging, and reconciliations are reviewed and signed off. This provides assurance the numbers are complete and accurate before financial statements are issued.

Q: How do you deal with aged, unexplained reconciling items?

Investigate root cause (posting errors, timing, disputes, duplicates), assign ownership and deadlines, and escalate persistent items. Immaterial residuals may be written off with proper approval after review; material or suspicious items require deeper investigation. Trending aged items highlights process weaknesses to fix at source.

Q: How does reconciliation support the financial-close controls and audit?

Reconciliations are key controls providing evidence that balances are complete and accurate. Auditors test that reconciliations are performed timely, reviewed independently, and that reconciling items are valid and cleared. Well-documented reconciliations reduce audit adjustments and support management's assertions and SOX control effectiveness.

What is a reconciliation in accounting?

Beginner

A reconciliation compares two independent records of the same thing to confirm they agree, and investigates/corrects any differences. In AP/AR it ensures sub-ledgers tie to the general ledger, ledgers tie to supplier/customer statements, and recorded cash ties to the bank. It's a core control that catches errors, omissions, and fraud.

Real-world example Each month-end the team reconciles the AR sub-ledger to the GL control account and resolves any differences before close.

What is a bank reconciliation?

Beginner

A bank reconciliation compares the company's cash ledger to the bank statement, explaining differences such as outstanding checks, deposits in transit, bank fees, interest, and errors. Reconciling to an agreed balance confirms recorded cash is accurate and surfaces unrecorded items or fraud like unauthorized withdrawals.

Book balance 10,000; Bank 11,200.
  + Deposits in transit 500  - Outstanding checks 1,800
  + Bank interest 100  - Bank fees 20 (adjust books)
  Reconciled balance agrees.

Real-world example The bank reconciliation reveals an unrecorded $20 bank fee and a $500 deposit in transit, tying book cash to the bank.

What is a sub-ledger to general-ledger reconciliation?

Beginner

It confirms that the detailed sub-ledger (e.g., the AP or AR aging, which lists every open invoice) totals to the single control-account balance in the general ledger. Differences arise from journals posted directly to the control account, timing, or posting errors, and must be investigated so the detail supports the GL.

AP sub-ledger total: 218,400
GL AP control:        218,900
Difference 500 = manual GL journal not in sub-ledger -> correct.

Real-world example A month-end AP reconciliation ties the vendor aging to the GL, catching a $500 direct journal that bypassed the sub-ledger.

What are reconciling items and how are they classified?

Intermediate

Reconciling items are the differences that explain a gap between two records. They're classified as timing differences (will self-correct, e.g., deposits in transit), permanent differences needing an adjusting entry (e.g., bank fees), and errors requiring correction. Documenting each with an action and owner is key to a clean reconciliation.

Real-world example A reconciliation lists a deposit in transit (timing), a bank fee (adjust books), and a miskeyed invoice (error to fix).

How do you reconcile a supplier statement to the AP ledger?

Intermediate

Compare the supplier's statement (what they say you owe) to your AP ledger for that vendor, line by line. Identify missing invoices to post, credits not yet applied, duplicate entries, disputed items, and timing differences (in-transit payments). Resolve each so the balances agree, preventing missed liabilities or over/underpayment.

Statement 52,000 vs ledger 48,500. Difference 3,500:
  +2,000 invoice not yet received, +2,000 invoice in dispute,
  -500 credit not on statement.

Real-world example A supplier statement reconciliation uncovers a $2,000 invoice never received and a missed $500 credit before payment.

What is the GR/IR reconciliation and why does it matter?

Intermediate

The GR/IR (goods-received/invoice-received) reconciliation analyzes the clearing account that holds the gap between receiving goods and receiving invoices. Open balances mean goods received but not invoiced (accrue) or invoiced but not received (investigate). Clearing it keeps liabilities accurate and prevents old, unexplained balances from accumulating.

Real-world example The quarterly GR/IR reconciliation accrues genuine received-not-invoiced liabilities and clears mismatches from quantity errors.

How do you reconcile intercompany AP/AR balances?

Intermediate

Intercompany reconciliation matches what one group entity owes (AP) against what the counterparty entity is owed (AR); they should mirror each other. Differences from timing, FX, disputes, or missed postings are identified and resolved before consolidation so intercompany balances eliminate cleanly and don't distort group results.

Real-world example Before consolidation, Entity A's $80k payable to Entity B is matched to B's receivable; a $3k timing gap is aligned.

What is the account reconciliation process at month-end close?

Advanced

At close, balance-sheet accounts (AP, AR, bank, GR/IR, accruals, prepayments) are reconciled: the ending balance is substantiated with supporting detail, reconciling items are documented with owners and aging, and reconciliations are reviewed and signed off. This provides assurance the numbers are complete and accurate before financial statements are issued.

Real-world example Every balance-sheet account has a signed-off reconciliation with supporting schedules before the CFO certifies the close.

How do you deal with aged, unexplained reconciling items?

Advanced

Investigate root cause (posting errors, timing, disputes, duplicates), assign ownership and deadlines, and escalate persistent items. Immaterial residuals may be written off with proper approval after review; material or suspicious items require deeper investigation. Trending aged items highlights process weaknesses to fix at source.

Real-world example A clean-up assigns owners to reconciling items over 90 days old, resolving most and writing off small residuals with approval.

How does reconciliation support the financial-close controls and audit?

Advanced

Reconciliations are key controls providing evidence that balances are complete and accurate. Auditors test that reconciliations are performed timely, reviewed independently, and that reconciling items are valid and cleared. Well-documented reconciliations reduce audit adjustments and support management's assertions and SOX control effectiveness.

Real-world example Auditors rely on timely, reviewed AP/AR reconciliations as evidence, reducing the substantive testing needed at year-end.
