Selling your service business: the price is set eighteen months before the buyer appears

The math, worked

An HVAC company with $2.4 million in revenue. Net profit on the tax return: $180,000. Add back the owner's $110,000 salary, $28,000 of personal vehicle and phone expenses, $19,000 of a one-time legal matter, and $64,000 of depreciation. SDE: $401,000.

With 8% recurring revenue, the owner running sales, and one commercial client at 22% of revenue, this business prices near the bottom of the range — about 2.2 times, or $882,000.

Now the same company after eighteen months of deliberate work: maintenance agreements grown to 38% of revenue, a service manager running daily operations, the concentrated client reduced to 12% by adding accounts, and books cleaned up. SDE rises to $455,000 through better margins, and the multiple moves to 3.4 — $1,547,000.

Same trucks, same technicians, same city. The $665,000 difference was created by decisions, not by growth.

Recurring revenue is the whole game

If there is one thing to act on years before selling, it is this. A maintenance agreement base does four things simultaneously: it smooths cash flow, it fills slow seasons, it produces the repair work that follows inspections, and it transfers to a buyer intact.

Three practices build it faster than any marketing:

• Offer the plan at the end of every completed job. Not by campaign, not by email — at the moment the customer is satisfied and standing in front of the technician.
• Charge monthly, automatically. Annual billing produces an annual decision to cancel. Monthly billing produces silence, which is what retention looks like.
• Track the count as a headline number. Active agreements is the single metric that most reliably predicts your eventual sale price.

The eighteen months before you sell

Almost everything that raises the price takes a year or more to become visible in the numbers. A realistic sequence:

• Months 1–3. Separate personal expenses from the business. Move to accrual-basis financial statements. Get two clean years on record — buyers and lenders want to see consistency, not a good final quarter.
• Months 4–9. Replace yourself in one visible role. Sales, dispatch or field supervision, whichever you personally hold. This is the hardest step and the one with the largest effect on the multiple.
• Months 10–15. Grow recurring revenue aggressively and reduce customer concentration. Document processes into written procedures.
• Months 16–18. Assemble the data room: financials, tax returns, customer list by revenue, contracts, equipment schedule, licenses, insurance, employee roster and pay structure, lease terms.

Owners who start this process when they are already exhausted sell at the bottom of the range, because fatigue is visible in the numbers and buyers price it.

Who actually buys these businesses

• Individual buyers. Frequently using SBA financing, which imposes real requirements: verifiable earnings, a business that can service debt, and usually a transition period from the seller. They pay reasonable multiples and represent the majority of transactions in this size range.
• Competitors. They understand the business and may pay more for route density or a customer list — but due diligence means opening your books to a rival, which is a genuine risk if the deal fails.
• Private equity roll-ups. Active in HVAC, plumbing, electrical, landscaping and roofing. They pay the highest multiples, require the most professional financials, and generally want the owner to stay for one to three years.
• Employees or family. Smoother transition, usually a lower price, and typically seller-financed over years — which means your payout depends on their success.

Deal structure matters as much as price

A headline number means little without the terms behind it. Four elements decide what you actually receive:

• Cash at closing. The only certain money in the transaction.
• Seller financing. Common and often necessary, but it makes you a lender to the person who now controls the business.
• Earnout. Payment contingent on future performance you no longer control. Treat any earnout as a possibility rather than as part of the price.
• Transition period and non-compete. How long you stay, in what role, and what you are prohibited from doing afterward — which matters enormously if you intend to work again.

A $1.4 million offer with $600,000 at closing and the rest on an earnout is frequently a worse deal than $1.15 million with $950,000 in cash.

Due diligence, and the things that kill deals late

Most transactions that fall apart do not fail on price. They fail during due diligence, sixty days in, when the buyer finds something the seller had stopped noticing. The pattern is consistent enough to prepare for.

• Worker classification. Crews paid as independent contractors who function as employees is the most common finding in this industry, and it creates a contingent liability a buyer will not assume. It is worth resolving well before a sale, not during one.
• Licensing held personally by the owner. In many trades the license is attached to a person, not to the company. If that person is you and you are leaving, the buyer needs a qualifying individual — and if none exists, the business cannot legally operate the day after closing.
• Customer contracts that do not transfer. Commercial agreements frequently contain assignment clauses requiring the client's consent on a change of ownership. A concentrated commercial account with such a clause is not the asset it appears to be until the client confirms in writing.
• Deferred maintenance on the fleet. Buyers get equipment inspected. Five trucks that each need $8,000 of work reduce the offer by $40,000, and there is no argument against it.
• Revenue recorded outside the books. Cash work is not discounted in a sale — it is invisible. A lender will not finance against it and a buyer cannot verify it, so it contributes nothing to the price no matter how real it was.

The practical response is to run diligence on yourself a year early. Hire an accountant to review the books the way a buyer's advisor would, confirm the license path, read the assignment clauses in every commercial contract, and fix what is fixable while there is no deal on the table and no leverage against you. Everything found early is a project; the same item found during diligence is a price reduction.

Five mistakes that cost owners money

• Running personal expenses through the business right up to the sale. Add-backs are scrutinized, and undocumented ones are simply removed from SDE.
• Being indispensable. Every function only you can perform is a deduction from the price.
• Selling in a bad year. Buyers weight the most recent twelve months most heavily.
• Ignoring recurring revenue until the year of sale. It takes two years to build and it moves the multiple more than anything else.
• Negotiating price without negotiating terms. Cash at closing is the number that matters.

What happens to the people, and why it affects the price

Owners tend to treat the workforce as a detail of the transaction and buyers treat it as most of the value. In a service business the technicians are the delivery capability, and a crew that leaves in the first ninety days turns a purchase into a rebuild.

Three things reassure a buyer and are worth building well before a sale. First, pay structures that are written and consistent — a company where compensation is negotiated individually and remembered verbally is one where the buyer cannot predict payroll or defend a decision. Second, tenure: a team averaging four years signals a workplace that functions, while constant turnover signals a problem the buyer will inherit. Third, a documented path from apprentice to lead, because a buyer paying for growth needs to know the company can staff it.

The related question is when to tell the team. Too early creates months of anxiety and resignations; too late feels like a betrayal to people who built the company with you. The common practice is to inform key staff shortly before closing, once the deal is essentially certain, with clarity about their roles and any retention arrangements — and buyers frequently fund retention bonuses for exactly this reason, because keeping the crew is cheaper than replacing it.

Five numbers a buyer will ask for first

• SDE for the last three years. Consistency matters more than the peak.
• Recurring revenue as a percentage of total. The strongest driver of your multiple.
• Revenue concentration in your top five customers. Above 40% combined is a discount.
• Owner hours and owner-performed functions. Directly convertible into a valuation adjustment.
• Customer retention rate. Proof that the revenue you are selling will still be there next year.

The uncomfortable truth about selling a service business is that the price is largely set years before the conversation with a buyer begins. The owner who spends eighteen months building recurring revenue, removing himself from daily operations and cleaning up the books is not preparing to sell — he is building the version of the business that was worth twice as much all along, and which happens to be far more pleasant to own in the meantime.

Frequently asked questions

How are small service businesses valued?

On SDE — seller's discretionary earnings — which is net profit plus the owner's salary, plus personal expenses run through the business, plus one-time items, plus depreciation and interest. It represents the total financial benefit available to a single owner-operator. For owner-operated service companies with SDE under roughly $1 million, the market typically pays 2 to 4 times SDE, and the position within that range is set by specific factors: recurring revenue share, which is the strongest single driver; owner dependence, where a business with a working general manager can be a full turn higher than one where the owner sells and dispatches; customer concentration, since one client at 30% of revenue is a discount rather than a strength; clean, verifiable books, because informally recorded revenue is not discounted but unbuyable; and equipment condition, where a fleet needing replacement in two years reduces the price by roughly the replacement cost. Above about $1 million to $1.5 million of EBITDA the buyer pool becomes financial rather than individual and multiples rise meaningfully.

What raises the sale price of a contracting business the most?

Recurring revenue, by a wide margin, followed by removing yourself from daily operations. A worked example: an HVAC company with $2.4 million in revenue and $180,000 of net profit, plus a $110,000 owner salary, $28,000 of personal expenses, $19,000 of one-time legal costs and $64,000 of depreciation, has SDE of $401,000. With 8% recurring revenue, the owner running sales and one commercial client at 22% of revenue, it prices near the bottom of the range at about 2.2 times, or $882,000. After eighteen months of deliberate work — maintenance agreements grown to 38% of revenue, a service manager running daily operations, the concentrated client reduced to 12%, and the books cleaned up — SDE rises to $455,000 and the multiple moves to 3.4, or $1,547,000. Same trucks, same technicians, same city, and a $665,000 difference created by decisions rather than growth.

How long does it take to prepare a service business for sale?

Realistically eighteen months, because almost everything that raises the price takes a year or more to become visible in the numbers. A workable sequence: months one to three, separate personal expenses from the business, move to accrual-basis statements and establish two clean years on record, since buyers and lenders want consistency rather than a good final quarter. Months four to nine, replace yourself in one visible role — sales, dispatch or field supervision, whichever you personally hold — which is the hardest step and the one with the largest effect on the multiple. Months ten to fifteen, grow recurring revenue aggressively, reduce customer concentration and document processes into written procedures. Months sixteen to eighteen, assemble the data room: financials, tax returns, customer list by revenue, contracts, equipment schedule, licenses, insurance, employee roster and pay structure, and lease terms. Owners who start when they are already exhausted sell at the bottom of the range, because fatigue is visible in the numbers.

Who buys small service businesses?

Four types, with different price levels and different requirements. Individual buyers, frequently using SBA financing, which imposes real conditions — verifiable earnings, a business that can service debt, and usually a transition period from the seller — and they represent the majority of transactions in this size range at reasonable multiples. Competitors, who understand the business and may pay more for route density or a customer list, though due diligence means opening your books to a rival, which is a genuine risk if the deal fails. Private equity roll-ups, active in HVAC, plumbing, electrical, landscaping and roofing, which pay the highest multiples, require the most professional financials and generally want the owner to stay one to three years. And employees or family, which gives a smoother transition at usually a lower price, typically seller-financed over years — meaning your payout depends on their success.

What kills a business sale during due diligence?

Five findings recur often enough to prepare for. Worker classification, where crews paid as independent contractors function as employees — the most common finding in this industry and a contingent liability a buyer will not assume. Licensing held personally by the owner, which in many trades is attached to a person rather than the company, meaning the buyer needs a qualifying individual or the business cannot legally operate the day after closing. Customer contracts that do not transfer, since commercial agreements frequently require the client's consent on a change of ownership, making a concentrated commercial account less of an asset than it appears. Deferred maintenance on the fleet, because buyers get equipment inspected and five trucks needing $8,000 each reduce the offer by $40,000. And revenue recorded outside the books, which is not discounted but invisible — a lender will not finance against it and a buyer cannot verify it. The practical answer is to run diligence on yourself a year early, while there is no deal on the table and no leverage against you.
