Twelve questions that actually come up in bookkeeper interviews — from screeners to the technical ones — with the shape of an answer that gets hired. Don't memorize these; understand them. Interviewers can tell the difference, and so can the job.
A strong answer: Accounts payable is money the business owes to vendors — bills we've received but not yet paid. Accounts receivable is the mirror image: money customers owe us for invoices we've sent. I keep an eye on both agings — A/P so we pay on time without draining cash early, A/R so collections never drift.
A strong answer: First I check for exactly $100 items: an unrecorded bank fee, a missed deposit, a duplicate. Then I look for two entries that net to $100, and I check for transposition errors — a $100 difference divisible by 9 often means digits swapped. What I never do is force it with an adjustment entry; the difference is information.
A strong answer: I don't guess silently. I park it in an 'ask my client' list and batch my questions — owners will answer one organized email a week, but not fifteen texts a day. Consistent categories matter more than clever ones, so once we decide, I document the decision.
A strong answer: Cash basis records income when money arrives and expenses when money leaves. Accrual records income when earned and expenses when incurred, regardless of cash timing. Accrual gives a truer performance picture; many small businesses file taxes on cash basis. I always confirm which basis the books and the reports should use.
A strong answer: Almost always, someone changed, deleted, or un-reconciled a transaction in a closed period. I'd use the audit log to find it, fix it properly, and then talk about setting a closing date with a password so finalized periods stay finalized.
A strong answer: Profit and cash are different measures. Profit counts invoices we've earned even if uncollected, and ignores loan principal payments, owner draws, and equipment purchases — all of which drain cash without touching profit. I'd show them the A/R aging and a simple cash summary. It's the most common owner question there is, and a good bookkeeper can answer it with two reports.
A strong answer: Unique credentials and two-factor authentication, no shared logins, client files in encrypted storage rather than email attachments, and access limited to what my role needs. And I never discuss one client's finances with another — discretion is most of the job's reputation.
A strong answer: Triage, not heroics: secure bank and card statements for the whole gap, get the feeds connected, then rebuild month by month — categorize, reconcile, and lock each month before moving to the next. I'd flag anything ambiguous for the owner in batches and give a realistic timeline up front rather than a hopeful one.
A strong answer: Profit & loss against last month and same month last year, balance sheet, A/R and A/P agings, and the reconciliation reports for every bank and card account. Then I look for anomalies — negative balances, uncategorized transactions, an Undeposited Funds balance that isn't clearing — before calling the month done.
A strong answer: Pick a real, small, specific story: a duplicated deposit inflating revenue, a loan payment fully expensed instead of split from principal, an owner draw hiding in expenses. Interviewers aren't testing perfection; they're testing whether you find errors, fix them properly, and say so plainly.
A strong answer: Practice, honestly. I keep certifications current — the ProAdvisor cert re-certifies regularly — and drill fundamentals so software changes are just new buttons on the same accounting. Daily practice habits beat cramming once a year.
A strong answer: Years aren't the same as habits. I reconcile every account every month, I document decisions, I ask instead of guessing, and I can show my skills right now on a certification exam or a sample file. Clean, current, boring books — that's the whole promise, and I keep it.
Interviewers increasingly ask candidates to do something: read a P&L aloud, spot the error in a sample ledger, or explain a reconciliation. The fix is reps, not scripts — run our free ProAdvisor readiness check and the bookkeeping certification check until the fundamentals are reflexes, and keep a daily streak going the week before the interview. Walking in with a certification — the ProAdvisor one is free — answers half these questions before you speak.
Module 1 of our course — what bookkeeping actually is, in plain English — is free forever, along with twelve free tools including an online ledger and the Simple Bookkeeping Spreadsheet. And the Daily Challenge gives you ten fresh questions every day, no signup.
