What Multiple Should You Pay for a Service Business Acquisition?
What Multiple Should You Pay for a Service Business Acquisition?
Most service businesses in the small business acquisition market trade between 2.0x and 4.5x SDE (Seller's Discretionary Earnings), with the exact multiple driven by industry, recurring revenue percentage, owner dependence, and transferability of customer relationships. Cleaning companies, mobile services, and owner-operated trades cluster at the lower end (2.0x to 3.0x). HVAC, electrical, and plumbing companies with strong service agreement bases command the upper end (3.5x to 4.5x). Landscaping sits in the middle (2.5x to 3.5x). The single biggest multiplier within any industry is recurring revenue — a service business with 40%+ of revenue under contract trades 0.5x to 1.0x higher than the same business with one-off project revenue. The second biggest multiplier is whether the business can run without the current owner. Owner-operator dependent businesses get the lowest multiples in their industry range. Systematized businesses with management teams in place get the highest. The data behind these ranges comes from BizBuySell quarterly insight reports and tracked transactions in the search fund and ETA community.
If you pay 4x SDE for a 2x business, you have overpaid by 100%. If you walk away from a 4x business priced at 2.5x because "the multiple seems high," you missed the deal of the year. Multiples are not opinions. They are market data points that match specific business profiles.
The right multiple is not the average multiple. The right multiple is what this specific business deserves based on its actual operating profile. A premium business at a discount multiple is the deal you write a thank-you note for.
The Industry Multiple Ranges
Here is the practical multiple range for each major service business category, with the operating profile that justifies each end of the range. These ranges align with reported transaction data from BizBuySell and the International Business Brokers Association market pulse surveys.
HVAC: 2.5x to 4.5x SDE
Why the range is wide: HVAC is the highest-multiple service business category because it combines recurring service agreements, licensed workforce scarcity, equipment brand authorizations, and recession-resistant demand. The bottom of the range is owner-operator residential repair shops with no service agreements. The top is systematized companies with 40%+ recurring revenue, tenured technicians, and authorized dealer status.
| Multiple | Profile |
|---|---|
| 2.5x - 3.0x | Owner-operator, no service agreements, aging fleet, residential only, no brand authorizations |
| 3.0x - 3.5x | Some service agreements (15-25% of revenue), stable workforce, mixed residential / light commercial |
| 3.5x - 4.0x | Strong service agreement base (25-40%), tenured techs, brand authorizations, modern fleet |
| 4.0x - 4.5x | Exceptional recurring revenue (40%+), systematized operations, commercial contracts, owner semi-absentee |

Plumbing: 2.5x to 4.0x SDE
Why the range is similar to HVAC: Plumbing shares many of HVAC's premium characteristics — licensed workforce, emergency service demand, recession-resistant — but typically has lower service agreement penetration because plumbing maintenance contracts are less common than HVAC tune-up agreements. The top end is reserved for plumbing companies that have built drain cleaning subscription models or commercial maintenance programs.
| Multiple | Profile |
|---|---|
| 2.5x - 3.0x | Single-truck owner-operator, no recurring revenue, residential only |
| 3.0x - 3.5x | 4-8 trucks, some commercial accounts, basic dispatch systems |
| 3.5x - 4.0x | Commercial maintenance contracts, tenured licensed plumbers, fleet under 5 years old, water heater install programs |
Electrical: 2.5x to 4.0x SDE
Why the range: Electrical companies face the same workforce licensing premium as HVAC and plumbing, but multiples top out slightly lower because recurring revenue mechanics are weaker. Electrical work is mostly project-based (panel upgrades, new construction, EV charger installs). Companies that have built service agreements around generator maintenance or recurring commercial maintenance command the upper end.
| Multiple | Profile |
|---|---|
| 2.5x - 3.0x | Owner-operator electrician, residential service calls only |
| 3.0x - 3.5x | Crew of 4-8 electricians, mix of residential and commercial, project-based revenue |
| 3.5x - 4.0x | Specialty practice (EV chargers, solar, generator service) with recurring component, commercial contracts, master electricians on staff |
Landscaping: 2.5x to 3.5x SDE
Why lower than the trades: Landscaping faces structural headwinds versus HVAC and plumbing — lower licensing barriers (fewer required certifications), seasonal revenue patterns in non-southern climates, and higher labor turnover. The upper end is reserved for landscape companies with strong commercial maintenance contracts (which provide year-round recurring revenue) or specialty design/build practices.
| Multiple | Profile |
|---|---|
| 2.5x - 3.0x | Residential mowing route, seasonal in northern climates, owner-operator with crew |
| 3.0x - 3.5x | Commercial maintenance contracts (HOAs, office parks), year-round revenue, design/build component, equipment fleet |
Cleaning (Commercial Janitorial): 2.0x to 3.0x SDE
Why the lowest range of the trades: Commercial cleaning has low barriers to entry (no licensing required), high labor turnover, thin margins, and highly transferable customer relationships (which sounds positive but means competitors can also poach your customers). The upper end of the range applies only to cleaning companies with multi-year contracts at scale or specialty cleaning (medical, biohazard, post-construction).
| Multiple | Profile |
|---|---|
| 2.0x - 2.5x | Owner-operator, monthly contracts, residential or small commercial |
| 2.5x - 3.0x | Multi-year commercial contracts (over $50K/year individual contracts), specialty cleaning, established crew supervisors |
Pest Control: 3.0x to 4.5x SDE
Why high multiples: Pest control is structurally one of the most attractive service business categories because it has true subscription revenue (quarterly or monthly recurring service contracts), high customer retention (80%+ annual retention for established companies), and resilient demand. PE rollups (Rentokil, Rollins/Orkin) have driven multiples up across the industry.
| Multiple | Profile |
|---|---|
| 3.0x - 3.5x | Owner-operator, residential routes, 60-70% recurring revenue |
| 3.5x - 4.0x | Systematized operations, technician training program, 70-80% recurring revenue |
| 4.0x - 4.5x | Commercial contracts, termite warranty book, 80%+ recurring revenue, multiple branches |
Roofing: 1.5x to 3.0x SDE
Why the lowest premium-trade range: Roofing is project-based with no recurring revenue (you do not need a roof "tune-up"), lumpy revenue patterns, weather-dependent operations, and high warranty exposure on completed work. Multiples reflect the structural risk. The upper end applies to roofing companies with insurance restoration practices or commercial flat roof maintenance contracts.
| Multiple | Profile |
|---|---|
| 1.5x - 2.0x | Storm chasers, project-only, no maintenance revenue |
| 2.0x - 2.5x | Established residential roofer, repeat customers, manufacturer certifications |
| 2.5x - 3.0x | Insurance restoration practice, commercial maintenance contracts, fleet and crew systematized |
What Drives Multiples Up
Within any industry range, four factors push the multiple toward the upper end. Each is worth approximately 0.25x to 0.5x in valuation.
Driver 1: Recurring revenue percentage. This is the single largest multiplier. A business with 40%+ of revenue under contract or subscription trades 0.5x to 1.0x higher than the same business with project-only revenue. Recurring revenue reduces customer acquisition cost (the customer is already won), provides cash flow predictability (lender-friendly), and creates switching costs (customer-friendly).
Driver 2: Owner replaceability. A business that runs without the owner present is worth substantially more than one where the owner is the operator. Specifically, lenders and buyers ask: "Could I hire a $90,000/year general manager and have this business continue functioning?" If yes, the business is replaceable-owner and trades at the top of its range. If the owner IS the salesperson, the technician, the dispatcher, and the bookkeeper, the business is owner-dependent and trades at the bottom.
Driver 3: Customer concentration. A business where no single customer represents more than 10-15% of revenue trades higher than one with concentration. The threshold matters because losing a 20% customer in year one wipes out your equity. Service businesses with diversified customer bases (50+ active customers, no concentration) command premium multiples.
Driver 4: Documented systems and processes. A business with documented operating procedures, organized financials, modern dispatch and billing software, and documented training programs is worth more than the same business operated from the owner's notebook. Systematization reduces transition risk and signals that the business will continue performing under new ownership.
What Drives Multiples Down
The same logic applies in reverse. Four factors push multiples toward the lower end of the industry range.
Drag 1: Workforce risk. High technician turnover, no documented training program, key technicians who might leave when the business sells, no employment agreements with key staff. A trades business losing 30% of its workforce annually is a substantially riskier asset than one losing 10%.
Drag 2: Equipment / fleet condition. Aging fleet that needs replacement within 24 months represents a hidden capital cost. A 6-truck HVAC fleet averaging 8 years old with 200,000+ miles is a $300K+ replacement bill that has to come out of someone's pocket. If the seller has not been replacing on cycle, the buyer pays.
Drag 3: Customer concentration on a single account. A roofing company where 40% of revenue comes from one general contractor, or an HVAC company where 35% of revenue comes from one property management firm. Lose that customer in year one and the deal economics implode. Lenders haircut multiples for concentration risk explicitly.
Drag 4: Pending lawsuits, regulatory issues, environmental liability. Anything that could create a tail liability for the new owner. Landscaping company with an OSHA violation history. Pest control company with EPA enforcement issues. Cleaning company with employment law lawsuits. These get priced into the multiple as risk discounts of 0.5x to 1.5x.
How Multiples Vary By Geography
The same business in different markets commands different multiples because buyer competition varies geographically.
Higher multiples (top of range or above): Florida, Texas, Arizona, the Carolinas, and Tennessee — markets with high in-migration, retiring baby boomer sellers, and active search fund / ETA buyer communities. A 3.5x HVAC company in Salt Lake City might trade at 4.0x in Tampa simply because there are more competing bidders.
Lower multiples (bottom of range or below): Rust Belt cities (Cleveland, Detroit, Buffalo), depopulating rural markets, and markets with limited acquisition financing access. A 3.5x HVAC business in Ohio might trade at 3.0x because there are fewer qualified buyers competing for it.
This is one reason why ETA searchers from the Northeast often relocate to Southern markets to find deals — but counter-intuitively, deal multiples are often better in Rust Belt geographies because of lower buyer competition. The tradeoff is the operational reality of running a business in a slower-growth market.
SBA Lender Multiple Caps
There is one practical ceiling on the multiple you can pay regardless of how attractive the business is: the SBA lender will not finance an acquisition where the multiple cannot be supported by cash flow. The math is simple — if the resulting debt service exceeds 1.25x DSCR, the loan does not get approved.
For a typical small business acquisition with 10% buyer equity and 90% SBA financing at current rates, the maximum financeable multiple is roughly 3.5x to 4.0x SDE. Above that, you either need more equity (15-25% down), seller financing on standby, or the deal doesn't get done at the asking price. This is why you see some businesses listed at 5x SDE sit on the market for 18 months. The asking price exceeds the financeable price, and only buyers with substantial equity can transact.
For more on SBA financing math, see the DSCR requirements guide.
How the BuyBox BRIT Score Connects to Multiples
The BuyBox BRIT Score evaluates each deal across four dimensions: Business Quality, Risk, Income/Return, and Transferability. The BRIT Score directly informs what multiple the business deserves — high BRIT scores justify upper-range multiples, low BRIT scores demand lower-range multiples.
The Transferability dimension (T) is especially relevant to multiple analysis. T-dimension scoring evaluates exactly the factors that drive multiples: owner replaceability, customer concentration, documented systems, workforce stability, and contract transferability. A business with a T-score of 9/10 deserves the upper end of its industry multiple range. A business with a T-score of 4/10 should not be paying upper-range multiples regardless of how strong other dimensions look — because the buyer will lose the value differential during the ownership transition.
How to Negotiate the Right Multiple
Once you know the range your business should fall in, the negotiation is about which end of the range you pay. The disciplined approach has three steps.
Step 1: Build the multiple argument. Score the business against the upper-end profile for its industry. For each criterion the business does NOT meet, calculate how much that should reduce the multiple. Example: HVAC business has only 12% recurring revenue (vs 40%+ for upper range), so deduct 0.5x. Aging fleet, deduct 0.25x. Owner is the lead salesperson, deduct 0.5x. Result: starting at 4.0x asking, defensible multiple is 2.75x.
Step 2: Present the analysis at the negotiation table. Sellers respond to data, not opinions. Walking through a structured analysis showing exactly which factors are pulling the multiple down (and why) is more persuasive than "I think your price is too high." Many sellers will adjust to a defensible number once they see the math. Some will not, in which case you walk away.
Step 3: Test multiple structures, not just a multiple. Sometimes a seller cannot accept a lower multiple but can accept a different deal structure that reduces your effective price. Examples: 4.0x with a $200K seller note on 5-year standby (effective Day-1 cost is closer to 3.6x). 4.0x with a 24-month earnout for 0.5x of the multiple (only paid if performance holds). 3.5x cash plus a non-compete payment that is tax-advantaged for the seller.
The buyer who can negotiate creatively often gets a defensible multiple even when the headline number stays at the seller's asking price.
Final Thought
Multiples are not random. They are market data points that reflect the actual risk-adjusted economic profile of the business being valued. The buyers who consistently close on great deals are the ones who can rapidly identify which industry range applies, where in that range a specific business should fall, and what structural changes could justify a different multiple.
Brokers will quote you the average multiple for the category. Sellers will quote you the upper-end multiple regardless of business quality. Your job as the buyer is to do the analysis that tells you what THIS specific business deserves — and to walk away from deals that cannot be transacted at a defensible multiple.
The business that justifies a 4x is worth paying 4x for. The business that justifies a 2.5x is a money pit at 4x. Knowing the difference is the entire game.
Score before you LOI.
