When it comes to selecting a certified public accountant (CPA) for your business, you’re choosing much more than someone to file tax returns. You’re selecting a partner who may impact strategy, cash flow, compliance and growth. Getting the right match matters.


Here’s a guide to help you interview, evaluate and decide — with key questions and practical advice.


Why this decision matters

Hiring the wrong CPA can cost more than fees: missed deductions, tax surprises, poor cash-flow forecasting, lack of strategic insight. Conversely, the right CPA becomes a trusted advisor, helping you structure your business, plan taxes, monitor cash flow, stay compliant and grow. As one article puts it:


“A good CPA does more than crunch numbers. They become a trusted advisor, helping you plan for taxes, stay compliant with regulations, and make smarter financial decisions year-round.” cpaoutsourcingservices.com
So before you commit, take the time to ask the right questions.



Key Questions to Ask When Hiring a CPA

Below are important questions — along with what you’re looking to learn from the answer, and warning signs to watch.



1. Are you a licensed CPA, and do you have a clean disciplinary record?

What to ask: “Are you licensed and in good standing with the state board of accountancy? Have you had any disciplinary actions?”


Why it matters:
 Only licensed CPAs are held to certain ethical and professional standards. proadvisorcpa.com+1


Red flag:
 They hedge the question or you can’t easily verify their license status.



2. Do you specialize in businesses like mine (industry, size, structure)?

What to ask: “Have you worked with companies in my industry (e.g., service, manufacturing, eCommerce)? What challenges are typical in that industry?”


Why it matters:
 Industry-specific experience means the CPA is more likely to understand your tax issues, regulatory environment, margins, cash flow cycles. Benjamin T Koeller CPA, PLLC+1


Red flag:
 The CPA has only done personal returns or unrelated business types and cannot articulate your industry’s issues.



3. What services do you offer beyond compliance (tax filing)?

What to ask: “What services do you provide: bookkeeping review, tax planning, cash flow forecasting, entity structure advice, financial reporting?”


Why it matters:
 If the CPA only does annual tax returns, you’re missing out on possible value. You want someone who supports your business year-round. Insogna CPA+1


Red flag:
 Their service description is vague or limited to “we’ll prepare your return.”



4. Who will actually handle my account and how will communication work?

What to ask: “Who will be my main point of contact? How available are you? What is your response time? Will I be working with you or someone else at your firm?”


Why it matters:
 Good communication is key. As one source says: “How do I contact you … what’s your policy on returning phone calls?” Benjamin T Koeller CPA, PLLC


Red flag:
 “Call our main number and we’ll assign someone” with unclear responsibilities or long response delays.



5. How do you charge for your services? What is included?

What to ask: “What is your fee structure — hourly, flat fee, retainer? What’s included and what will cost extra? Can you provide an estimate?”


Why it matters:
 Fees should be transparent. Hidden costs, unclear inclusions, or a mystery pricing model are risks. Accounting Insights


Red flag:
 They cannot give you a ballpark or keep adding “extra work” fees without prior notice. Equally alarming should be ridiculously low fees, if a firm is charging hundreds less than anyone else, odds are there is a reason. 



6. How proactive is your tax planning and business strategy support?

What to ask: “Do you meet outside tax-season? Will you review my entity structure, cash flow, strategic opportunities? What is your approach to long-term tax/business planning?”


Why it matters:
 As business owner you benefit from a CPA who actively helps you plan, not just react. Insogna CPA+1


Red flag:
 They say “we’ll talk again during tax season” with little other strategic engagement.



7. What technologies, tools and systems do you use?

What to ask: “What bookkeeping, tax software and client-portal tools do you use? How do you exchange documents? How secure is the data?”


Why it matters:
 Modern, efficient, secure systems save time, reduce errors and make collaboration easier — especially if you’re remote. Hiline


Red flag:
 The firm is still paper-only or can’t explain how they secure client data.



8. What happens if there’s an audit or major issue?

What to ask: “If I’m audited, will you represent me? What’s your fee for that? What support do you provide in risk-review and prevention?”


Why it matters:
 Audit risks exist — you want a CPA who stands behind their work and has your back. ADP


Red flag:
 They “may” help but aren’t clear on the process or cost if it happens.



9. How will you help me grow and adapt as my business changes?

What to ask: “As I expand, enter new states, change business structure or launch new products, how will you support me? What additional services do you offer for growth phases?”


Why it matters:
 Your business isn’t static — you’ll need a CPA who can scale with you and advise accordingly.


Red flag:
 They only talk about “doing your tax return each year” and not about business future or growth.



10. Who will I be working with and how accessible are they? 

What to ask: “Will I have a dedicated contact, or contacts, within the firm for questions as they come up?"


Why it matters:
 You need to know who to call with questions and ideally 1-2 people who can always be involved with you specifically. If they have so many employees, who is really looking out for you? Also, if it's a single contact, what happens when they get sick, go on vacation, leave? 


Red flag:
 They can't give you a name or process of how new clients are brought on and who to call. 



How to Decide: Fit & Feel

Once you’ve asked these questions, reflect:


Did the CPA listen and understand your business?

Did they answer in plain English (not just accounting-jargon)?

Did you feel comfortable, trusted their process, and believe they proactively care?

Was their approach aligned with your business goals (growth, stability, compliance)?

Was the fee structure clear and acceptable?


A long-term CPA relationship is just that — long term. The right fit eases your mind, supports decisions and becomes a strategic advantage.



Final Thoughts

Selecting the right CPA is one of the most important decisions you make for your business. Done well, you gain much more than tax returns — you gain a partner who helps you navigate risk, seize opportunity, manage cash flow and grow. If you rush or settle for a minimal fit, you may miss out on meaningful value.



If you’re ready to interview CPAs, use the above questions as your guide. If you already have a CPA but think the fit isn’t right, consider revisiting the conversation or exploring better alignment.

In my last post, I talked about starting this firm from the back of a closet with one client, a makeshift desk, and an old power strip. But I didn’t start a CPA firm because I had always dreamed of owning a CPA firm. I started it because the traditional model didn’t make sense to me — especially after starting a small side business of my own and seeing things from the business owner’s side. Clients would send information into a black hole and wonder when they would hear back. Business owners would meet with their accountant after the year was already over, when most of the opportunities to actually change the outcome were gone. Large firms often reserved their best advice and attention for their largest clients, even though smaller business owners arguably needed that guidance more. Tax returns became the service instead of what I believed they should be: the end result of conversations happening throughout the year. And too often, the accountant knew the numbers but didn’t really know the business. None of that made sense to me. I thought a CPA firm could be more than the place you send documents once a year. I thought we could help business owners make better decisions before those decisions showed up on a tax return. That idea became the foundation of the firm. Pricing was another problem. At the first firm I worked for, we had “dynamic” pricing. In practice, that could mean charging a client more after a good year to supposedly make up for years when their bill had been discounted. Other clients might go an incredibly long time without receiving a bill, only to suddenly get hit with a huge invoice. As someone trying to run a business myself, I couldn’t understand that. How could a business owner budget for a professional relationship without knowing what it was going to cost? The traditional model was built around billing for time, yet employees were constantly being told to work faster. That created the wrong incentives. The focus became completing the deliverable efficiently instead of asking what else the client needed to know. Payroll could become an afterthought. Bookkeeping could become work used to fill the slower months. Questions about a client’s history could be viewed as time taking away from the task at hand. The system rewarded completing work. I wanted a system that rewarded helping the client. So when I started the firm in 2017, the concept was pretty simple. Find out what the client actually needs. Agree on the scope. Give them a predictable monthly price. Review that relationship every 9–12 months and adjust when their needs change. And most importantly, don’t disappear between tax returns. From the beginning, I wanted the relationship to include tax return preparation, mid-year tax planning, year-end planning, and responsive communication throughout the year. At the time, proactive planning and upfront pricing were far less common in the small-business CPA market. A business owner getting a call that said, “Let’s meet in July and see how the first half of the year went,” was not the experience many owners expected from their accountant. But it made perfect sense to me. If we waited until tax season to have that conversation, we weren’t planning anymore. We were reporting history. The response was great — once I could get business owners to give a new firm a chance. Over time, that simple concept grew into something much bigger. People smarter than me helped develop it into what the profession now broadly calls advisory, with a much wider scope and greater ambition than what I originally envisioned. But the underlying idea hasn’t changed. Business owners deserve to know what they’re paying. They deserve honest advice, even when the answer isn’t what they expected. They deserve regular conversations about what is happening in their business and what is coming next. And they deserve a CPA who understands that the goal isn’t simply to produce an accurate tax return. The goal is to help them make better decisions before we get there. That’s why I started the firm. Transparent pricing. Honest advice. Regular conversations.  Built for Business Owners. CPA Led. Strategy Focused.

An old power strip from my beginning became an unexpected reminder of how easy it is for business owners to overlook how far they’ve come.
