Start with industry experience. “Have you worked with businesses like mine?” matters more than general years of experience. A bookkeeper who understands your industry already knows the common expense categories, the seasonal patterns, and the pitfalls that trip up businesses in your space. Someone learning your industry on the job will make mistakes that cost you time and money.

Ask what software they use and whether they’re proficient in it. If you’re already on QuickBooks Online, you want someone who works in it daily and not someone who’s “willing to learn.” Ask how they handle bank feeds, reconciliation, and reporting within the platform. Vague answers here usually mean limited experience.

“What’s included in your monthly fee?” is essential. Some bookkeepers include transaction categorization, reconciliation, and monthly financial statements in one price. Others charge extra for reconciliation, year-end cleanup, or reports. Get specifics so you’re not surprised by add-on charges three months in. Also ask how they handle months with higher-than-usual transaction volume.

Ask how often you’ll communicate and in what format. Will you get monthly financial statements with a summary of what’s happening? Can you call or email with questions throughout the month? Some bookkeepers disappear after onboarding and you only hear from them when something goes wrong. Regular communication is what separates a true partner from someone just processing transactions.

“How do you coordinate with my tax preparer at year end?” is a question most people forget to ask. Your bookkeeper’s work feeds directly into your small business tax returns. If the books aren’t clean and organized in a way your CPA or tax preparer can use, you’ll pay extra for cleanup or miss deductions. The best bookkeepers already have a process for packaging year-end financials for tax filing.

Ask who will actually be doing the work. At larger firms, the person you talk to during the sales process isn’t always the person touching your books. Find out if your work gets handed to a junior team member or outsourced. There’s nothing inherently wrong with that, but you should know upfront.

“What happens if you find errors or issues in my current books?” is a revealing question. A good bookkeeper will explain how they handle catch-up work, what it costs, and how long it takes. If they wave it off or don’t seem concerned about getting a clean starting point, that’s a red flag.

Finally, ask for references from current clients. Any bookkeeper confident in their work will happily connect you with someone who can vouch for them. If they hesitate or can’t provide any, keep looking.

The right full-service bookkeeping partner should answer all of these questions clearly and without getting defensive. How someone handles your questions before you hire them tells you a lot about how they’ll handle your business after you do.
