How Do CPA and Accounting Firms Get Clients?

By Christoph Olivier, Founder, CO Consulting

Last reviewed: July 2026

Most CPA and accounting firms get clients the same way they always have: through referrals from happy clients and trusted professionals. What has changed is that the referral now checks you out online before they call. So the modern answer is a system, not a single tactic. You earn word of mouth, then you make sure that word of mouth finds a firm that looks credible in local search, in reviews, and on the topics your ideal client is worried about. Below is how the pieces fit together, with the AICPA advertising rules kept in view.

The short answer: where accounting clients actually come from

Accounting firms win clients through five channels that reinforce each other: referrals from clients and centers of influence, a clear industry niche, local search and Google Business Profile, online reviews and proof, and content plus LinkedIn that reach business owners directly. Referrals lead by a wide margin, but they convert better when the other four are working.

Accounting is also seasonal. Tax season floods you with contacts and gives you no time to nurture them, while the summer lull is when firms that planned ahead do their client-acquisition work. Build the machine off-season so it runs when you are busy.

Why referrals still dominate accounting firm growth

Referrals dominate because trust and money sit close together, and a peer recommendation carries that trust for you. Industry surveys put referrals as the top source of new business for about 89% of firms, and roughly 58% of businesses say they found their accountant through a peer referral versus only about 3% from advertising. Existing tax clients are the single richest vein, contributing the majority of referrals for top performers.

The mistake is treating referrals as luck. Firms that ask on purpose beat firms that wait. A structured referral motion outperforms the occasional “send us anyone you know” line at the bottom of an email.

How to build a referral engine on purpose

A referral engine is a repeatable habit, not a campaign. Segment your best clients in your CRM by industry, size, and loyalty, then ask them at the right moment with a specific request. The point is to make referring you easy and to make the ask normal rather than awkward.

1. Identify your 20 most loyal, highest-fit clients and tag them.
2. Ask right after a win: a clean return, a tax saving, a solved problem, or a strong satisfaction score.
3. Be specific. “Do you know another dental practice owner who dreads bookkeeping?” beats “know anyone who needs an accountant?”
4. Close the loop. Thank the referrer, and tell them how it went within the bounds your state board allows.

One caution on incentives. The AICPA and many state boards limit how you pay for or solicit referrals, and coercive solicitation is off limits. Keep referral thank-yous modest, disclosed where required, and never tied to attest clients. When in doubt, a handwritten note and reciprocity beat a cash bounty.

Build centers of influence with adjacent professionals

Centers of influence, or COIs, are the professionals who already advise your ideal client and can send you a stream of qualified work. For accounting firms that usually means estate planning attorneys, business attorneys, financial advisors, bankers, and insurance agents. A handful of strong COI relationships can outproduce dozens of one-off client referrals.

Reciprocity is the whole game. Refer work out first, meet quarterly, and give the COI something to hand their clients, like a plain-language guide on entity choice or year-end tax moves. The firms that win here treat COIs as partners they serve, not a list they mine.

Pick a niche before you pick a tactic

Choosing a niche is the highest-impact decision most firms avoid. When you specialize in an industry, referrals get more precise, your marketing gets cheaper because the message is sharper, and your fees go up. Research shows clients will pay meaningfully more for a firm that clearly serves their field, and practices that draw more than half their revenue from defined niches report materially higher revenue per client.

A niche can be an industry (dental practices, restaurants, construction, SaaS founders), a service (R&D credits, multi-state sales tax, outsourced controller work), or a client stage (first-time business owners, firms preparing to sell). Pick one where you already have a few happy clients and a story to tell. If you want help turning that positioning into a full plan and offer, that is exactly what our marketing for CPA and accounting firms work is built around.

Show up in local search and Google Business Profile

Local search is where the referral confirms you and where “CPA near me” searchers find you. Most people who hear your name will search it, and a strong Google Business Profile plus consistent local listings decide whether that search ends in a booked call or a shrug. This is the cheapest credibility you can build.

Start with the basics that move the map pack:

• Claim and complete your Google Business Profile with correct hours, services, and categories.
• Keep your name, address, and phone number identical everywhere online.
• Post updates and answer questions, especially before and during tax season.
• Build a service page for each core offering so search engines and buyers understand what you do.

Turn reviews and proof into a client-acquisition asset

Reviews are the quiet closer. A referred prospect and a local searcher both check your reviews before they call, so a steady flow of recent, specific reviews validates every other channel you run. Two or three fresh reviews a month usually beat a pile of old ones.

Make the ask part of your workflow. After a clean filing or a solved problem, send a short message with a direct link to your Google profile. You can guide clients on what was helpful, but you cannot script or selectively suppress reviews, and honesty rules apply. Alongside reviews, short anonymized case notes (“how we cut a contractor’s estimated-tax surprises”) give referrals and searchers the proof they need, provided you protect client confidentiality.

Use content and LinkedIn to reach business owners directly

Content and LinkedIn reach owners before they start shopping, which is how you stop competing on price. When you answer the questions a business owner actually types or asks, you show up as the expert who gets it, and you feed both search engines and the AI tools buyers now use to shortlist firms. This is the channel that compounds.

You do not need to publish daily. A focused rhythm works better:

• Write for your niche. One clear article on “how restaurant owners should handle tip reporting” beats ten generic tax posts.
• Repurpose. Turn each article into a LinkedIn post, a client email, and a talking point for COIs.
• Be the source. Specific numbers, real examples, and plain language get quoted, shared, and cited.

Move from compliance work to advisory, and market it

Advisory positioning changes who you attract and what you can charge. As Client Advisory Services (CAS) grow, firms that lead with insight rather than compliance win better clients and keep them longer. CAS practices have reported median growth around 17%, and firms leaning into CFO-level advisory report higher recurring revenue. Clients rarely leave a specialist advisor to go back to a commodity preparer.

The marketing implication is simple. Talk about outcomes, not forms. “We help owners see their numbers monthly and make better decisions” attracts a different client than “tax returns prepared.” Advisory work also gives you a reason to stay in touch all year, which feeds referrals and reviews. No guarantees, of course, but the direction of travel is clear.

Stay inside the AICPA and state board advertising rules

Every tactic above sits under the AICPA Code of Professional Conduct, specifically the advertising and solicitation rules in section 1.600. Marketing that is false, misleading, or deceptive is prohibited, and so is soliciting clients through coercion, overreaching, or harassment. Your state board layers its own advertising rules on top, and independence rules limit how you market to attest clients.

In practice this means a few guardrails: no promises of specific refunds or savings, no fake or incentivized reviews, no claims you cannot back up, and care around testimonials from audit or attest clients. None of this blunts good marketing. It just keeps you credible, which is the entire point of the profession.

A simple 90-day plan to get more accounting clients

You do not need every channel at once. Sequence the work so each step feeds the next, and build during the off-season so it runs during tax season.

1. Weeks 1 to 2: Pick one niche and write a one-line positioning statement.
2. Weeks 3 to 4: Claim and complete your Google Business Profile and fix listing consistency.
3. Weeks 5 to 6: Tag your top 20 clients and start asking for referrals after wins.
4. Weeks 7 to 8: Set up a review request in your workflow and collect three testimonials.
5. Weeks 9 to 10: Meet two potential COIs and refer work to them first.
6. Weeks 11 to 12: Publish two niche articles and repurpose them on LinkedIn.

Run that loop, measure what books calls, and double down. If you would rather have a partner build the plan and run it with you, book a consultation and we will map it to your firm.

Frequently asked questions

What is the fastest way for a new accounting firm to get clients?
The fastest path is direct outreach to a defined niche plus referral asks to everyone you already know. Pick one industry, tell every past contact and COI exactly who you help, and claim your Google Business Profile so name searches convert. New firms win on focus and follow-up long before content or ads pay off.

Do referrals really matter more than advertising for CPAs?
Yes. Surveys put referrals as the top source of new business for roughly 89% of firms, while only about 3% of businesses find their accountant through advertising. Trust drives accounting decisions, and a peer recommendation carries that trust. Advertising can support a referral, but it rarely replaces one.

Should my accounting firm pick a niche?
Almost always. A niche sharpens your message, improves referral quality, and lets you charge more because clients pay a premium for a specialist in their field. Choose an industry, service, or client stage where you already have happy clients and a clear story, then build your marketing around that single focus.

Are online reviews allowed under AICPA rules?
Genuine reviews are fine and valuable. What the AICPA Code prohibits is false, misleading, or deceptive marketing, which rules out fake reviews, scripted testimonials, or selectively hiding negative feedback. You may ask satisfied clients to review you and remind them what was helpful, provided you protect confidentiality and stay honest.

How much should an accounting firm spend on marketing?
There is no single right number, and it depends on growth goals and margins. Many professional-services firms budget a single-digit percentage of revenue, weighted toward the off-season. More useful than a percentage is tracking what books calls, so referrals, local search, and content each earn their place in the budget over time.

How long does it take to see results?
Referral and local-search improvements can produce calls within weeks, while content and advisory positioning compound over six to twelve months. There are no guarantees, and results vary with your niche, market, and consistency. The firms that win treat client acquisition as an ongoing system rather than a one-time push.
