Selling a professional services firm in Quebec
The value of a professional firm is measured by what survives the founder's departure: clients, team, recurring revenue and the professional-order framework.
Professional services in Quebec
Professional services cover very different worlds — each with its own selling logic, and each with its own ownership rules.
- Accounting and tax (CPA) — Governed by the Quebec Order of Chartered Professional Accountants. More than 50% of voting ownership must rest with practising CPAs. Strong recurring revenue (compliance, tax, payroll), and very active consolidation.
- Engineering — Governed by the Ordre des ingénieurs du Québec (OIQ). A mix of project work and technical services, with frequent public contracts. Size and order-book depth drive the multiple.
- Legal services and notarial practice — Barreau du Québec and Chambre des notaires. Ownership is reserved for members of the order, narrowing the buyer pool to peers. Transfers happen almost exclusively between members or through internal succession.
- Management consulting, communications and marketing agencies, HR services — Not governed by an order. Value rests almost entirely on client portfolio transferability and the depth of the team beyond the founder.
Out of scope on this page. IT consulting, managed services (MSPs), and cybersecurity are covered on our technology page. Medical, dental, veterinary, optometry and physiotherapy clinics, plus pharmacies, are covered on our healthcare and wellness page — their regulatory framework (consolidatable clinics, MSO structures, practitioner ownership) calls for a different lens.
From here on, we're talking about Quebec SMEs with $2 to $30 million in revenue, regardless of sub-segment. Because at that size, two cross-cutting axes drive what a buyer pays: revenue recurrence (recurring engagements vs. one-off projects) and client transferability (firm-level relationships vs. founder-level relationships).

Professional services are one of Quebec's robust economic engines: 7.8% of real GDP in 2024, up from 6.4% in 2019. The sector employs about 380,000 people at an average hourly wage of $43.04.
The structure is massively fragmented: of 27,600 employer establishments, roughly 18,600 are micro-firms with 1 to 4 employees. For a buyer, most SMEs still look like founder practices where the client base is attached to people, not to a system.
Recent trends are mixed. Strong structural growth in engineering (infrastructure, energy, decarbonization). Job losses, on the other hand, in accounting and legal services between 2022 and 2024 — a signal that consolidation is absorbing small practices faster than organic growth creates jobs.
Quebec's modest real growth in 2025 (+0.7%) is sharpening buyer selectivity: they favour contracted recurring revenue over one-off engagements, and demand more protection mechanisms (holdbacks, vendor take-backs, earn-outs) on founder-dependent firms.

What's specific to selling a professional services firm
Selling a business in Quebec follows steps common to every industry. But in professional services, you're selling trust (the client base) and capability (the team). Four sector issues shape the deal.
Client transferability is risk #1
In an industry dominated by micro-firms, the client relationship is often personal. The client calls you, signs with you, trusts you. The first question a serious buyer asks is always the same: "what happens to those clients if the founder walks away?"
To protect value, a personal relationship has to become a firm-level relationship before going to market. Buyers look for more than one contact per account, an engagement lead who isn't you, and renewal history attributable to the team.
When that proof is missing, the buyer doesn't walk away from the deal — they restructure it. A larger earn-out, a longer transition, tighter non-solicitation clauses. You get the headline price, but a substantial slice stays conditional on post-closing performance.
Recurring revenue is the real multiple driver
Not all revenue in a professional services firm is valued the same way. The most prized form of recurrence is the kind that survives a change of ownership: contracted retainers, recurring engagements (tax compliance, bookkeeping, payroll), documented multi-year commitments.
The gap between contracted recurrence and one-off engagements feeds straight into the multiple. An accounting firm with 70% to 80% recurring revenue trades meaningfully higher than a consulting firm at the same EBITDA that resells hours project by project.
For a firm without natural subscriptions, the lever is to prove repeatability. No formal contract? Document the pipeline, the renewal history per client, the sector diversification. A one-off engagement that comes back every year becomes, statistically, recurring revenue — provided the documentation backs it up.
Professional orders filter your eligible buyers
Several Quebec professional orders impose an ownership rule that restricts who can hold voting control of a firm. These rules are neither administrative trivia nor negotiable.
For CPAs, more than 50% of voting rights must be held by practising chartered professional accountants. Engineering, legal and notarial practices carry their own constraints through the OIQ, Barreau du Québec and Chambre des notaires.
The effect is mechanical. A private equity fund can't buy a CPA firm the way it would buy a manufacturing SME; it needs a two-tier structure, and some buyers walk away from that complexity. Strategic consolidators and internal buyouts become the dominant routes.
For a seller, the practical takeaway is to structure the firm in advance. The order's regulation, the shareholders' agreement and the allocation of voting shares dictate who can buy. If that structure isn't aligned, the buyer pool collapses during diligence.
The long earn-out has become the dominant deal mechanic
In most industries, the earn-out is still the exception. In professional services, it has become the norm.
Two forces converge: tighter Canadian bank credit, which reduces cash available at closing, and client attrition risk after the founder leaves. Together, they push buyers to make part of the price conditional.
The typical structure: 10% to 30% of the price tied to revenue or retention over 1 to 3 years. For an individual buyer, it can stretch to 24-36 months, or longer in an internal buyout.
The seller's work is to negotiate a workable earn-out: achievable targets, readable metrics, access to measurement, and ideally a floor even if the target isn't hit.

Typical multiples
Professional services are too broad for a single multiple. A founder-dependent consulting practice, a recurring-revenue CPA firm, a creative agency and an engineering firm don't trade at the same level. The dominant factor is the business model: recurrence, founder dependency and regulatory constraints.
For a broader read on how these gaps play out by industry, our analysis of valuation multiples by industry documents how the logic shows up in Quebec SME transactions. And before applying a range, normalized EBITDA has to reflect a market-rate founder salary (not actual compensation), market-rate rent, and the deduction of non-recurring items.
Multiple ranges — SME professional services
Base: Normalized EBITDA (after market-rate founder salary) · SDE for very small practices
Boutique consulting heavily dependent on the founder
Multiple of seller's discretionary earnings (SDE), not EBITDA. The owner is the product; transferability is limited.
Accounting (CPA) — SME with recurring revenue
Recurring compliance, tax and payroll work supports the multiple. The > 50% voting-rights rule filters eligible buyers.
Engineering — backlog and public-sector contracts
Size premium above $5M EBITDA, with strong order-book visibility. The OIQ governs ownership structure.
Communications, marketing and creative agencies
Retainers and account diversification lift the multiple; dependence on a single "rainmaker" compresses it.
Indicative market benchmarks, not a price promise. Final value is established deal by deal: normalized valuation basis, transferability, sector-specific risks, deal structure and real buyer competition.
What pushes the multiple up
- Contracted recurring revenue (retainers, recurring engagements, subscriptions) — this is the most powerful factor in the sector. An accounting firm where 70% to 80% of revenue comes from recurring engagements survives any change of ownership; the buyer pays a premium worth several turns of multiple.
- An autonomous team with low founder dependency — engagement leads, a stable technical bench, a documented junior-intermediate-senior pyramid. The buyer isn't buying your billable hours, they're buying the team's capacity to generate them without you.
- Client diversification with no single account above 20% to 25% of revenue — losing a client during the transition doesn't threaten profitability.
- Niche expertise with high barriers — specialized engineering, regulatory and tax compliance, regulated industries with high barriers. Scarce expertise translates into pricing power and defensible margins.
- High digital maturity (an integrated management system, a client platform, automated deliverables) — the buyer can plug the firm into a larger platform without friction. The premium can reach 20% to 30% over a competitor still operating on fragmented tools.
What pushes the multiple down
- The founder as both business developer and primary practitioner — all the value rests on your address book and your billable hours. The multiple shifts from EBITDA to seller's discretionary earnings, which sharply reduces valuation.
- Project-based revenue with no documented renewal history — no proven recurrence means no premium. The buyer models attrition risk during the transition.
- Critical client concentration — above 25% from a single account, it's an existential risk. The buyer shares it through holdbacks, earn-outs, or a flat discount.
- High turnover among key talent — in a sector with endemic talent shortages, the buyer can't rebuild the team in a few weeks. Visible turnover signals operational fragility and scares off serious buyers.
- A dominant personal brand ("John Smith & Associates," where John is the product) — value attaches to your name, not to the firm. The required transition stretches; the earn-out widens.
- A shareholders' agreement non-compliant with the order's requirements (CPA, OIQ, Barreau, Chambre des notaires) — voting rights misallocated, share transfers improperly framed. The buyer prices that risk through escrow or discount, or simply walks away.

Who buys professional services firms in Quebec?
The market is shaped by two forces working together. Consolidation by strategic buyers — other firms acquiring certified teams and loyal client portfolios. And internal buyouts — partners, key managers, professional cooperatives — often the only realistic route in professions where the order limits outside ownership.
Who buys and why
Firms in active consolidation — Mallette, the RCGT/PSB Boisjoli alliance, large national networks. They buy certified teams that can't be hired organically, loyal client portfolios, and geographic coverage.
Often the only realistic route in regulated professions (CPA, engineering, legal, notarial) where voting ownership must rest with members of the order. Long planning horizon (5 to 7 years), typically financed with a vendor take-back, BDC, and Investissement Québec.
Former executives of large firms or search-fund operators. They target structured SMEs with stable cash flow. Marginal in regulated professions, where order qualification is a prerequisite.
Indicative view of the buyer pool, not market data. Percentages show the relative weight of profiles to approach; the outcome of a transaction depends on file quality, process confidentiality and the competition created.
Case in point — Mallette. In 2024-2025, the Quebec accounting firm rolled out an aggressive consolidation strategy, reaching 4th place among the largest Quebec firms and expanding to New Brunswick through the acquisition of Paulin Gagnon CPA. The logic is typical: acquire certified teams, loyal client portfolios and geographic coverage.
Case in point — RCGT and PSB Boisjoli alliance. The combination illustrates the other dynamic: two sizeable Quebec players joining forces to challenge the Big Four in Montreal. This is platform positioning, not a founder exit.
For an owner thinking about selling, value rests less on revenue alone than on the scarcity of your expertise, team retention, client transferability, and the cleanliness of your regulatory and corporate file.
The next step is creating real competition without alerting key clients or key talent. Strategic consolidators, internal successors, order constraints, earn-outs and transition planning all need to move inside the same frame. That's exactly the role of a business broker in Quebec: running the process, protecting information and bringing the right buyers to the table.

Frequently asked questions — Selling a professional services firm
If my clients call me directly, is the firm even sellable?
Yes, but a buyer will treat that dependency as a risk and make the deal more conditional: a larger earn-out, a longer transition, tighter non-solicitation clauses.
To protect value, prove before going to market that the client base belongs to the firm: more than one relationship per account, an engagement lead who isn't you, and renewal history attributable to the team.
Is the old "1x revenue" rule for a firm still valid?
No. Buyers price firms on normalized EBITDA and cash-flow quality. A firm with 25% EBITDA margin and contracted revenue is worth more than a firm at the same revenue with 10% margin and no contracts. Buyers pay for transferable cash flow, not billing volume.
Should I expect an earn-out, and why has it become the norm?
Yes. Tighter bank credit reduces cash available at closing, and client-attrition risk pushes buyers to tie part of the price to performance.
The typical structure is 10% to 30% of the price tied to revenue or retention over 1 to 3 years. The seller's work is to negotiate an achievable target, readable metrics and access to the measurement mechanism.
How long will I have to stay after the sale?
Typically 6 months to 3 years, depending on the buyer profile and how dependent the firm is on you personally.
A strategic competitor with their own management team may settle for 6 to 12 months of transition. An individual buyer will often require 1 to 3 years to transfer key client relationships. For an internal buyout (partners or key managers), the ideal handover runs 5 to 7 years — typically financed through a vendor take-back, BDC, and Investissement Québec.
Can the departure of key employees sink the sale?
Yes. In a sector with skilled-talent shortages, a buyer can't replace a departed team in a few weeks. High turnover or weak employment agreements will sink offers or block the deal.
The work happens well before going to market: internal non-solicitation clauses, transaction-linked retention bonuses and a written retention plan for key profiles.
