Word-of-Mouth in accounting firms: Systematize it without waiting for it to happen

Ask ten Canadian accounting firms where their clients come from, and the majority will say “word of mouth.” That’s no surprise. Choosing an accountant is a matter of trust, and nothing builds trust faster than a recommendation from someone you know. Nielsen’s Global Trust in Advertising study has confirmed this for years: recommendations from people you know remain the most credible source of information in the world, far ahead of any form of advertising.

The problem, then, isn’t the quality of the channel, it’s how it’s managed. Word-of-mouth left to chance can bring in excellent clients, but only when it wants to, at its own pace, and often among the very client base you’re trying to expand. This guide shows how to transform passive word-of-mouth into an active referral system: when to ask, whom to ask, what Tools to use, within what ethical framework, and how to scale it without compromising its integrity when your practice needs to grow faster than its reputation can spread.

Why word of mouth remains the top marketing channel for practices

A referred client brings three advantages that no other channel offers all at once:

• Trust has already been established. Your client has already done the legwork to win them over for you. The first call isn’t meant to prove you’re serious, but to define the scope of the engagement.
• The direct acquisition cost is virtually zero. No advertising, no buying leads: sales time is reduced, and the margin on the engagement is preserved starting in the first year. To put this into perspective, a business client in Canada pays a median of approximately $3,000 per year for accounting services, ranging from $500 to $6,000 depending on the industry (Bankeo Fee Barometer 2024-2026, data drawn from over 15,000 requests received); a client acquired without advertising costs is profitable starting in the first fiscal year. Details can be found in the Bankeo Fee Barometer of Accounting Fees.
• Patient loyalty is higher. A client who comes through a referral is building a relationship, not just comparing prices. They stay longer and, in turn, recommend the practice to others: the channel feeds itself.

In a market where, according to CPA Canada, there are more than 220,000 CPAs in the country, this relational advantage is no small matter: it’s often what sets firms that choose their clients apart from those that take whatever comes their way.

The limitations of passive Word-of-Mouth

Practice managers are well aware of the downside: spontaneous word-of-mouth cannot be controlled. It has four structural flaws.

• It’s unpredictable. Three referrals one month, zero the next quarter. It’s impossible to build a hiring plan or set a growth target based on a channel you don’t manage.
• It’s slow. Reputation spreads as fast as conversations do. A practice that wants to double its client base in three years can’t just wait for the Market to talk about it.
• It mirrors your current customer base. Your clients recommend people who are like them. If you want to move upmarket, switch industries, or specialize, word-of-mouth will hold you back. This topic ties in with the discussion in Specialize or Stay a Generalist.
• It’s quietly losing steam. When service quality slips, referrals dry up without warning. You don’t realize there’s a problem until six months later, when you check the appointment book.

The good news is that each of these limitations can be addressed. The difference between passive word-of-mouth and a systematic word-of-mouth strategy comes down to a few management practices.

Systematizing referrals: When, to whom, and how

Asking for a referral makes many professionals uncomfortable. Yet it’s a service you’re providing to your clients: most of your best clients would be happy to help you, but they simply don’t think of it. Three rules make the process feel natural.

• Choose the moment when satisfaction is at its peak. Right after a tangible result: a tax return filed early, catch-up accounting completed, a tax savings opportunity identified, or financing secured thanks to solid financial statements. That’s when the phrase “If you know an entrepreneur in the same situation, we’d be happy to help them” really hits home.
• Targeting the Right Brand Ambassadors. Not all clients are equally effective as advocates. Identify your ten most satisfied and well-connected clients (executives active in an industry association, a chamber of commerce, or a business network) and nurture those relationships. This hands-on approach aligns with what is described in Networking for an Accounting Firm.
• Make it easy. A referral often falls through because the client doesn’t know what to say. Give them a simple tool: an appointment booking page, a brief introduction to the practice, or a template email they can forward. The less friction there is, the more likely the referral will succeed.

Add a measurement process: When opening each new case, note the source (referral, Google search, platform, partner). Without this data, it’s impossible to know whether your word-of-mouth is growing or slowing down, or to compare your channels with one another, as suggested by A Comparison of a Practice’s Marketing Channels.

“Word-of-mouth is the reward for trust. But a practice that waits for its clients to talk about it is confusing reputation with strategy. The best practices we see at Bankeo do both: they earn recommendations, and they ask for them.” Brian Bergeron, founder of Bankeo

Amplifying the effect: Google reviews, referral partners, and an ethical framework

Digital word-of-mouth amplifies local word-of-mouth. An entrepreneur who’s been recommended your firm will look you up on Google before calling: your listing, your rating, and recent reviews will either confirm or refute what they’ve been told about you. An excellent in-person reputation that’s invisible online loses some of its recommendations as they come soon. The full process is detailed in Google Reviews for an Accounting Firm.

Second driver: the Referring Partners. Lawyers, mortgage brokers, bankers, financial planners, and insurance brokers come into contact every week with business owners who need an accountant. A network of three or four active partners is worth dozens of client advocates, because the recommendations are consistent and professional.

A word of caution is in order whenever a counterparty is involved. Recommending and being recommended for free poses no problem. However, if compensation is paid or received for a client referral, the provincial codes of ethics for CPAs govern the practice: transparency toward the client in question and the preservation of professional independence, with stricter restrictions for assurance engagements. Before formalizing a referral agreement, check your provincial accountant association’s code of ethics; the rule-by-rule guidelines can be found in Client Referrals and the CPA Code in Canada.

Supplementing Word-of-Mouth marketing when growth demands it

Even when systematized, word-of-mouth has its limits: it grows only as fast as your existing client base. A practice that wants to accelerate growth, fill a new position, or break into a sector where it doesn’t yet have clients needs a second, predictable source of business.

That’s where pre-qualified leads come in. The principle of Bankeo Pro builds on the concept of word-of-mouth, but on a market-wide scale: an entrepreneur describes their specific need (industry, type of business, deadline), the request is verified, and then matched with firms whose profiles match, often within 48 hours. Since 2023, Bankeo has received more than 15,000 requests from entrepreneurs, and its network includes more than 1,500 registered accounting firms; in Canada, hundreds of deals have been closed between entrepreneurs and accounting firms in the network. The model is transparent: a fee per file, known in advance, never a percentage of your fees. You keep 100% of your billing, and the referral remains what it should be: a trusted matching service.

The two channels reinforce each other: a client who arrived through a pre-qualified lead and received excellent service becomes an ambassador in turn, as shown by Building client loyalty at an accounting firm. And the time you no longer spend on cold calling, quantified in Time Wasted Looking for Clients, reinvests in service, that is, in the raw material of word-of-mouth.

Key takeaways. Word-of-mouth is your most cost-effective channel, but it only becomes a growth driver if you manage it effectively: ask for referrals when client satisfaction is at its peak, equip your client ambassadors, make your reputation visible on Google, track the source of each new lead, and supplement the flow with pre-qualified leads when your goals exceed the natural pace of referrals.

Frequently asked questions

Is word-of-mouth enough to grow an accounting firm? To maintain a stable client base, often yes. To grow, rarely: this channel is slow, unpredictable, and merely replicates your current client base. Growing practices systematize it and supplement it with a predictable channel, such as pre-qualified leads.

When Should You Ask a Client for a Recommendation? At the peak of satisfaction: right after a successful project, an identified cost savings, or a resolved issue. The request should be specific (“Do you know a business owner who’s in the same situation?”) rather than general.

Can you pay someone who refers clients to the practice? This practice is governed by the provincial codes of ethics for CPAs: transparency with clients and the preservation of independence are required, with stricter restrictions for attestation engagements. Check your professional association’s code before entering into any agreement.

How Can You Measure Your Word-of-Mouth Marketing? Record the source of each new case when it’s opened: referral from a client, referring partner, Google search, or platform. Track the breakdown each quarter; a decline in referrals is a warning sign regarding client satisfaction.

Are Google Reviews Replacing Word-of-Mouth? No, they’re extending it. The business owner who’s been referred to you almost always checks your Google listing before calling. Recent, detailed reviews reinforce the recommendation; an empty listing undermines it.

Does Bankeo take a percentage of referred clients? No. Bankeo does not charge any commission: the service is billed as a fee per file, with fees known in advance and never tied to your fees. You keep 100% of your billing.
