What Makes a Service Business Sellable: 6 Tests

Roughly half of the trade businesses that go to market never sell.

A 2025 HVAC M&A report from First Page Sage put it plainly: about 52% of HVAC companies that go to market do not sell, and the two reasons it names for buyer hesitation are owner dependence and customer attrition. The Exit Planning Institute has estimated that only 20% to 30% of businesses listed at any one time end up transacting.

That matters more in Canada than almost anywhere, because the supply is about to spike. CFIB found 76% of Canadian small business owners plan to exit within the next decade, moving over $2 trillion in business assets, with retirement the top reason cited by 75%. CIBC's economics team, citing the same research, notes that only 9% have a formal succession plan.

So the question is not whether your shop is worth something. It is whether you will be the seller who gets a competitive offer, or the one whose listing sits for a year.

The short answer

A service business is sellable when a stranger can look at your records and conclude the revenue will still arrive after you leave. Everything else follows from that. Owner dependency, recurring revenue, customer concentration and clean books are not four separate virtues, they are four ways of answering the same question, and each is answered with a document rather than a claim.

The clearest version of this came from a contractor answering a valuation question on r/smallbusiness: "If you have management in place that can keep running the business in your absence, it's worth 3-5x earnings. If the business cannot operate without you, it's worth Assets - Liabilities."

That is the whole spread, stated in one sentence by someone with no incentive to flatter you.

The average multiple is an illusion

The commonly quoted benchmark from the BizBuySell Insight Reports for Main Street deals in 2026 sits flat around 2.7x SDE. Treat that number as a midpoint between two markets that barely touch.

An M&A practitioner writing in r/buyingabusiness in 2026 broke the current market into two tiers, and the description matches what lenders and brokers say elsewhere:

For essential trades specifically, HVAC, plumbing and electrical, that post put premium owner-independent shops at 3.2x to 4.5x SDE on Main Street, rising past 5.5x to 7x EBITDA once a company clears roughly $2 million of EBITDA.

The gap between those tiers on a $400,000 SDE shop is about $680,000. Nobody pays you that for working harder. They pay it for evidence.

SDE is not EBITDA, and the charts you are reading are not about you

This is the single most expensive misunderstanding in exit planning for trades.

SDE (seller's discretionary earnings) adds your salary and personal benefits back to profit. It describes what a working owner takes home. EBITDA does not add back a market-rate manager's wage, because it assumes someone is being paid to do your job.

So when you read that HVAC companies trade at 8x EBITDA, check the fine print. First Page Sage's own table shows residential all-purpose HVAC at 6.3x EBITDA in the $500,000 to $1 million EBITDA band and 10.8x in the $5 million to $10 million band. Those are companies with a management layer, a fleet and a finance function.

Meanwhile a Certified Exit Planning Advisor answering an HVAC owner in r/smallbusiness gave the number that actually applies: "its probably your SDE times 2-4 if your business is in HVAC and under $700k in SDE." Another deal advisor in the same thread said 2.5x to 3.5x.

If you value your shop off an EBITDA chart built from lower-middle-market transactions, you will price 30% to 50% high, sit on the market, and eventually accept less than you would have if you had priced it correctly on day one.

The six tests a buyer actually runs

Every one of these is answered from your systems. That is the point of the section.

1. The owner test

Buyers do not ask whether the business depends on you. They test it. An exit advisory firm describes the mechanics: in early meetings they ask your team questions when you are out of the room and watch whether people answer or defer, and during reference calls they ask customers who they call when something goes wrong. If the answer is always you, that is priced.

The same firm splits owner dependency into three kinds worth naming separately: relationship (customers stay because of you), decision (every pricing and hiring call routes through you), and knowledge (your pricing logic and vendor terms exist only in your head). Their illustration of the cost: the same business with $300,000 of SDE might sell for $600,000 owner-dependent and messy, or $1.2 million clean and transferable.

An M&A firm's case study makes it concrete. A small IT services owner who personally managed every client relationship attracted real initial interest, then watched it evaporate during diligence. The business sold for 60% of what he hoped for, plus a job, because he was needed to transfer the goodwill he had never transferred.

2. The records test

This is where most trades shops quietly fail, and it is fixable.

Legal guidance for home services M&A is explicit about what buyers request: field service management software data exports that include job histories for individual customer accounts, so the buyer can trace which maintenance visits converted into repairs and replacements. The same guidance notes that smaller companies often cannot produce that data in structured form, because they know their revenue mix but never recorded which repair followed which visit.

You cannot build that history in the 60 days after signing a letter of intent. Either your job and customer records captured it as work happened, or the buyer discounts for an unproven number.

The premium tier description is equally blunt about the standard: systems that generate clean, audit-ready data rather than "a spreadsheet someone updates on Fridays."

3. The recurring revenue test

Maintenance agreements are the highest-leverage asset a trades business can build before an exit, and buyers scrutinize them harder than owners expect.

They will ask for renewal rate by vintage year, meaning the percentage of plans sold in each year that are still active, precisely because a flat headline retention number can be propped up by auto-renewal while satisfaction rots underneath. They will separate voluntary cancellations from moves and system replacements. They will model conversion to repair, since that downstream revenue, not the plan fee, is usually the real economic value of the portfolio.

One more thing owners rarely anticipate: prepaid plan revenue is a liability you are handing over. Every dollar of prepaid maintenance sitting on your balance sheet at closing is service the buyer must deliver, and it gets treated as an assumed obligation in the working capital adjustment. Recurring revenue still raises your price. It just does not raise your cheque by the full sticker amount.

4. The concentration test

If one customer, one builder or one property manager represents a large share of revenue, the buyer prices the risk that the relationship leaves with you. Practitioners commonly flag concentration at 15% or more of revenue as a diligence issue alongside poor records and owner dependence.

The fix is not a sales tactic, it is a reporting one: you need revenue by customer, by year, in a form you can hand over. Most shops discover during diligence that they have never actually looked at that report.

5. The transfer test

Ask a lawyer this before you decide how to sell, because it interacts with tax in a way that surprises people.

Anti-assignment clauses are standard in residential service agreements. In a share sale, the contracting entity does not change, so those clauses are not triggered. In an asset sale, the contracts must be assigned, which can require customer consent, and mass consent solicitation gives every customer an occasion to cancel. The structure that is better for your taxes is frequently also the structure that preserves your recurring revenue.

6. The financing test

Your buyer's lender is a second gatekeeper with its own opinion of your records. An M&A lender put it directly in that same Reddit thread: when a company is heavily dependent on the owner or lacks financial and operational infrastructure, both valuation and leverage capacity compress. Less debt available means a smaller pool of buyers, which means less competition, which means a lower price. Owner dependency costs you twice.

The Canadian layer nobody in the search results covers

Almost every article on this topic is written for a US seller with an SBA-financed buyer. The mechanics here are different in two ways that are worth real money.

Structure is the tax

Selling shares of a qualified small business corporation can shelter a large capital gain under the lifetime capital gains exemption. The CRA states the LCGE at $1,250,000 for 2025 dispositions of qualifying property including QSBC shares, and Canadian accounting firms put the indexed 2026 figure at $1,275,000.

Selling assets, the equipment and the customer list, does not access that exemption at all.

Two more points of context, because the last three years produced a lot of noise:

• The proposed increase in the capital gains inclusion rate to 66.67% was deferred in January 2025 and then cancelled in March 2025. The 50% inclusion rate stands.
• The Canadian Entrepreneurs' Incentive, which would have reduced the inclusion rate to one third on up to $2 million of gains, now appears cancelled, per Doane Grant Thornton's own headline on the measure. Notably, the draft rules excluded consulting and professional practices but not the trades. Plan around the LCGE that exists rather than the incentive that did not survive.

Your customer list is not a standalone product

There is a common wind-down plan in the trades: close the shop, sell the trucks, sell the customer list and redirect the website. A contractor described exactly that pattern in r/smallbusiness as what happens when an owner never understood they were running a job rather than a business.

In Canada, that plan collides with privacy law. PIPEDA section 7.2 lets parties to a business transaction use and disclose customer personal information without consent, provided they have an agreement limiting use to the transaction, apply appropriate safeguards, return or destroy the data if the deal dies, and notify affected individuals within a reasonable time after closing. But the section carries an express limitation: it does not apply where the primary purpose or result of the transaction is the purchase or sale of personal information.

A list sale is the one structure the exception was written to exclude. It also fails the tax test, since it is an asset sale. Two independent reasons the fallback plan is worth less than owners assume.

How Canadian buyers actually fund the deal

There is no SBA here, so the capital stack looks different, and knowing it helps you structure a deal that closes.

• Down payment: 20% to 30% of the purchase price is BDC's stated rule of thumb.
• Vendor take-back: typically 10% to 15% of the transaction, per BDC, usually repaid over three to five years, often with the first year deferred, and almost always subordinate to the bank.
• CSBFP has a ceiling that surprises people. Under program guidelines a maximum of $150,000 of a CSBF loan can go to intangible assets and working capital, and vendor take-back amounts are not eligible for a CSBF loan at all. It is not an acquisition-goodwill program.

Ontario owners discussing this in r/SmallBusinessCanada described the practical splits. One buyer: "Bank wouldn't give me anything without insane conditions, BDC had no problem financing the purchase so the 0/100 split was pretty easy to decide on." Another: "BDC 2/3, Seller financed 1/3." A financing broker in the same thread summarized it as BDC doing higher loan-to-value while banks offer better rates.

Expect to carry paper. BDC also notes that the first 18 months after an ownership transition are the riskiest period, which is exactly why buyers and lenders want the seller financially attached to the outcome.

The 24-month sequence

Advisors repeat 12 to 24 months for a reason, and the order matters more than the duration.

Only about 15% of owners planning to sell have ever had a valuation done. Start there, because every other decision on this list depends on knowing whether you are in the discount tier today.

What this costs if you do nothing

Assume a shop doing $400,000 in SDE. In the discount tier at 1.8x it is worth roughly $720,000. In the premium tier at 3.8x it is roughly $1.52 million. The difference is $800,000, and most of it is bridged by records you could be keeping starting Monday: which customer, which job, which quote, which technician, which renewal, which source.

Then add the structural layer. A share sale that qualifies for the exemption can shelter up to $1,275,000 of that gain in 2026. An equipment-and-list wind-down cannot shelter any of it.

The uncomfortable version of all this is that "sellable" is largely a documentation problem wearing an operations costume. The businesses that transact at the top of the range are not necessarily better run day to day. They are better recorded, and they can prove in an afternoon what the other seller can only assert.

If you want the operational half of the same argument, the case for tracking every job from lead to invoice and for systematically working past customers is the same case made in the present tense. The exit is just where the invoice for skipping it finally arrives.
