Computerized Bookkeeping Interview Questions & Answers

Q: What are IT general controls relevant to a computerized accounting system?

IT general controls include access security (passwords, roles, MFA), change management (controlled software updates), backup and recovery, and computer operations. They ensure the environment in which the accounting application runs is secure and reliable, so the automated processing and data can be trusted.

Q: How does software help with VAT returns?

The software applies VAT codes to transactions, accumulates output and input VAT, and produces the VAT return figures automatically. Under digital filing regimes it can submit the return electronically. This reduces calculation errors and speeds compliance, though correct VAT coding by the user is still essential.

Q: What is the benefit of automatic bank rules/matching in software?

Bank rules automatically categorize and match recurring bank transactions (e.g., always code a certain payee to a given expense), and matching links imported bank lines to existing invoices/payments. This speeds reconciliation, improves consistency, and reduces manual coding effort and errors, while unusual items still need review.

Q: How do you ensure data integrity when importing data into accounting software?

Validate imports by reconciling control totals (counts and amounts) before and after, checking for duplicates and mapping fields to the correct nominal codes, running the import in a test/backup first, and reviewing the resulting trial balance. Opening balances and prior data must reconcile so the import doesn't corrupt the records.

Q: What does 'Making Tax Digital' (or similar digital tax rules) require?

Digital tax regimes like the UK's Making Tax Digital require businesses to keep digital records and submit tax returns (e.g., VAT) using compatible software rather than manual or copy-typed figures. This pushes businesses toward computerized bookkeeping with digital links from records to the return.

Q: How do you reconcile a control account in accounting software?

The software maintains control accounts (receivables/payables) automatically and provides aged reports listing the underlying balances. Reconciliation compares the control account balance to the aged detail (they should match automatically) and investigates any manual journals posted directly to the control account, which can cause differences.

Advanced

IT general controls include access security (passwords, roles, MFA), change management (controlled software updates), backup and recovery, and computer operations. They ensure the environment in which the accounting application runs is secure and reliable, so the automated processing and data can be trusted.

Real-world example Enforcing multi-factor login and controlled updates protects the integrity of the accounting data.

How does software help with VAT returns?

Beginner

The software applies VAT codes to transactions, accumulates output and input VAT, and produces the VAT return figures automatically. Under digital filing regimes it can submit the return electronically. This reduces calculation errors and speeds compliance, though correct VAT coding by the user is still essential.

Real-world example At quarter-end the software generates the VAT return totals ready to submit digitally.

What is the benefit of automatic bank rules/matching in software?

Intermediate

Bank rules automatically categorize and match recurring bank transactions (e.g., always code a certain payee to a given expense), and matching links imported bank lines to existing invoices/payments. This speeds reconciliation, improves consistency, and reduces manual coding effort and errors, while unusual items still need review.

Real-world example A rule auto-codes the monthly broadband direct debit, so reconciliation needs no manual entry for it.

Validate imports by reconciling control totals (counts and amounts) before and after, checking for duplicates and mapping fields to the correct nominal codes, running the import in a test/backup first, and reviewing the resulting trial balance. Opening balances and prior data must reconcile so the import doesn't corrupt the records.

Real-world example Before going live, the bookkeeper reconciles imported totals to the source and reviews the trial balance for errors.

Digital tax regimes like the UK's Making Tax Digital require businesses to keep digital records and submit tax returns (e.g., VAT) using compatible software rather than manual or copy-typed figures. This pushes businesses toward computerized bookkeeping with digital links from records to the return.

Real-world example A VAT-registered business uses MTD-compatible software to keep digital records and file returns.

How do you reconcile a control account in accounting software?

Intermediate

The software maintains control accounts (receivables/payables) automatically and provides aged reports listing the underlying balances. Reconciliation compares the control account balance to the aged detail (they should match automatically) and investigates any manual journals posted directly to the control account, which can cause differences.

Real-world example The aged receivables total should equal the receivables control balance; a manual journal to the control account is the usual culprit if not.
