Best M&A Advisors for
Business Services

Which Businesses Does This Guide Cover?

This guide covers founder-owned companies that sell services to other businesses, in six groups:

• Facility services: commercial cleaning and janitorial, pest control, commercial landscaping.
• Field and trade services: HVAC, plumbing, electrical, fire and life safety.
• Professional services: accounting and CPA firms, consulting, engineering, insurance brokerage, marketing.
• Staffing and workforce services.
• IT and managed services: MSPs and IT services firms.
• Outsourced processing: receivables management, revenue-cycle and BPO-style work.

Each group sells to a different set of buyers at a different multiple. Our guide to business services valuation multiples sets out the published ranges by vertical, and if you run a cleaning company, start with how to sell a commercial cleaning business.

What ties them together in a buyer's mind is simpler than it looks: they deliver recurring value to business customers (not consumers), they scale through people and systems rather than inventory, and their valuation depends far more heavily on how much of the business actually survives the founder's departure than it does for a product business.

What Buyers Actually Underwrite

When a buyer evaluates a business services company, they focus on a few things in particular, and an advisor who understands these gets better outcomes for owners who understand them too.

• Customer concentration. How many customers account for a meaningful portion of revenue? Service businesses that are heavily reliant on one or two large contracts are riskier to acquire, and buyers will discount for that risk.
• Contract-based vs. project-based revenue. Recurring, contracted revenue is worth far more than one-time project work. A buyer paying for stability needs to see stable revenue. This is often the single biggest value driver in the space.
• Customer retention and switching costs. Are your customer relationships sticky? Do customers stay because they have to, or because they want to? Service businesses whose customers would find it genuinely painful to switch command higher multiples than those that compete on price alone.
• Management depth beyond the owner. This is where most service business owners leave value on the table. If the business depends on you personally to close deals, deliver work, or manage relationships, the buyer is not buying a business, they are buying a job. Building a team the business can run without you often adds more value than anything else an owner can do before a sale.
• Pricing discipline and margins. Service businesses built on low prices are hard to sell. Buyers look for real margins and evidence that you price for value, not just volume.

Who Is Actively Acquiring in Business Services

Business services has one of the deepest buyer pools in the lower middle market, which works in an owner's favor. A few names dominate:

• Springdale Industries. A permanent capital vehicle reporting “375+ partner companies” and more than 700 individual equity partners, founded by Jake Sloane and Frank Zhang (Springdale). Its pitch to founders is that “business builders should stay at the helm,” so management generally stays rather than being replaced. Worth knowing the vehicle itself began operations in April 2025, though its founders have been acquiring businesses together since 2016.
• Alpine Investors. The most relevant name for many B2B services owners, because Alpine builds platforms that then acquire relentlessly. In 2024 its HVAC, plumbing and electrical platform Apex Service Partners completed 47 acquisitions, its managed-IT platform Evergreen Services Group 32, its accounting platform Ascend 14, and its infrastructure and engineering platform Trilon 11 (Alpine).
• Shore Capital Partners. Recognized by PitchBook for leading US private equity deal volume across the ten years from 2015 to 2024, with assets under management above $14 billion after closing $850 million across two new funds (Shore Capital). Its model is built specifically around founder-owned businesses at lower middle market size.

Beyond these names, there are dozens of smaller PE-backed platforms, strategic acquirers in specific verticals, and family offices actively buying in business services. The key is that unlike some industries where buyers are few, business services has real competition. That competition is your leverage.

What Advisors Charge, and What the Market Looks Like

Two numbers are worth knowing before you take a single meeting. The first is how much of the deal market you are competing in. Axial, a lower middle market deal network, reports that B2B services transactions made up almost 20% of all deals brought to its platform, with the majority concentrated in IT services, marketing services, and staffing services (Axial). That is a crowded field, which cuts both ways: plenty of buyers, but your business has to stand out on paper. IT services is the largest slice of it, and it prices differently from the rest of business services, because buyers separate contracted managed-services revenue from project and resale work before applying a multiple. If that is your vertical, see our guide to MSP valuation multiples and our page on selling an MSP.

The second is fees, which you can benchmark before an engagement letter appears. The Firmex M&A Fee Guide, run annually with Axial and Divestopedia, models a sell-side success fee of about 6.3% on a $5 million transaction, 3.9% at $20 million, and 2.0% at $100 million in its 2023–24 US edition of 189 US respondents; its 2024–25 global edition of 456 respondents models 4.8%, 3.4%, and 2.0% at those same sizes. On engagement fees, the more recent Axial 2026 M&A Fee Guide found that 71% of advisors charge some form of upfront fee, and 77% credit it toward the success fee. Such fees are typically owed during the engagement and are not refunded if the deal fails, so ask every firm whether it charges one, how much, and whether it is credited, and get the answer in writing.

Momentum varies sharply by vertical, which is the strongest practical argument for hiring someone who lives in yours. Each vertical has its own active platforms and its own pace of deals, and a generalist reading headline middle-market data can miss that.

How We Evaluated These Firms

Each advisor below was assessed against four criteria. First, vertical fit: does the firm actually transact in your specific corner of business services, rather than listing it as one of a dozen industries. Second, deal-size fit: is a founder-owned company at your revenue level squarely inside its range instead of at the bottom of it. Third, verifiable evidence: can the track record be confirmed from something other than the firm's own marketing, whether an Axial league-table placement or a published transaction. Fourth, who does the work, and whether the person pitching you runs your process.

Where a claim comes only from a firm's own website, it is cited to that firm and labelled as self-reported. Where a ranking is cited, it is attributed to the body that published it. Axial rankings deserve a specific note: Axial states that its league tables use only first-party platform data and that “no self-reported data or paid placements factor into the results,” and its Q3 2026 table evaluated more than 400 investment banks and advisory firms (Axial). The limit is eligibility: only Axial member firms that marketed a qualifying deal in the period can be ranked, so absence from the table proves nothing. Salt Creek Advisory is not on it. On fees, none of the firms below publishes a fee schedule, so this article reports no fee percentages for any of them. The fee terms column shows only the fee structure each firm states, and the published market benchmarks above give you something to hold each one against.

Comparison at a Glance

Salt Creek Advisory wrote this comparison and ranks itself first for founder-owned business services companies with $2 million to $75 million in revenue; the reasons are in its profile below. Ranks shown for other firms are Axial Q3 2026 league-table placements (published October 2026), with Q2 2026 shown where it differs, and carry the eligibility limits described above.

Salt Creek Advisory Best Overall

Salt Creek Advisory is a family-owned lower middle market investment bank based in Chicago, working with founder-owned businesses in the $2 million to $75 million revenue range, roughly $500,000 to $5 million of EBITDA. Business services is one of its five sector practices, alongside early childhood education, industrials, MSP and IT services, and pet care, and it represents sellers only. Both principals have worked on the buyer side: Jack Pitts worked in private equity business development at Blue Wolf Capital and Kingfish Capital and in investment banking at ButcherJoseph & Co., and Connor Pitts worked in corporate development at Cadence Education, an early childhood education acquirer, across two stints from 2021 to 2026 (with a 2023 stint in investment banking at Brown Gibbons Lang & Company), and worked on more than 40 transactions on the buy side. That matters in this sector specifically, because the platforms named above negotiate deals for a living and run the same playbook every time. Both founders work every engagement personally, and the firm charges no retainer and no monthly fee: it is paid a success fee at closing. Some engagements start with a small deposit, credited against the success fee at closing.

Who should pick someone else: if you run a receivables-management or revenue-cycle business, Kaulkin Ginsberg has covered that niche since 1991 and we have not. If your deal needs cross-border reach, a capital raise alongside a partial sale, or a large banking team, FOCUS or Peakstone are better equipped. We are a young two-person firm, so there are periods when we cannot take a new mandate, and we do not carry a published league-table rank.

Best for: founder-owned B2B services companies in the $2M–$75M range whose owners want both principals personally running the process against PE platform buyers.

The Advisory Investment Bank

The Advisory Investment Bank works exclusively with essential and field-services businesses: HVAC, plumbing, electrical, landscaping, pest control, fire safety, waste management, roofing and more than thirty other trade verticals, generating $2 million to $100 million in revenue with at least five years of operating history (The Advisory). Its proprietary AI platform maintains profiles on more than 4,500 private equity firms and strategic acquirers, an unusually deep sourcing capability at this deal size. Axial ranked it #1 among all lower middle market investment banks for Q2 2026 (Axial) and #2 for Q3 2026, out of more than 400 firms evaluated each quarter, on a methodology using only first-party platform data with no paid placements (Axial). It works on a 100% success-fee model with no retainers. Full profile in our guide to top lower middle market investment banks.

Best for: owners of HVAC, plumbing, electrical, landscaping and similar field-services businesses, especially those attracted by a no-retainer model. Less suited to professional services or knowledge-work businesses outside the trades.

FOCUS Investment Banking

FOCUS Investment Banking has been operating since 1982 and describes itself as “a premier global middle market investment bank,” with global partners across 36 countries (FOCUS), and says it specializes in transactions from $10 million to $150 million (FOCUS). It runs dedicated industry teams, and business services and technology services are both among them, covering insurance brokers, legal services, managed service providers and professional services specifically. Axial ranked it #9 for Q2 2026 and #5 for Q3 2026 (Axial), and it also appeared on Axial's business services advisor list.

Two things to weigh. Its stated range starts around $10 million, so a smaller founder-owned company sits at the bottom of the band, and it is worth asking which specific banker would own your process. Against that, the international partner network is a genuine advantage if a foreign strategic acquirer is a plausible buyer, which is more common in IT and professional services than owners expect.

Best for: business services and IT services companies at the larger end of the lower middle market, or any owner who wants meaningful cross-border buyer reach.

Kaulkin Ginsberg

Kaulkin Ginsberg is the narrowest specialist here and, for the right owner, a natural first call. Based in Germantown, Maryland, it has advised the accounts receivable management industry since 1991 and positions itself as the leading M&A and strategic advisor to the outsourced business services sector, concentrating on receivables management, revenue cycle management and customer relationship management, predominantly in healthcare, government, education and financial services (Kaulkin Ginsberg). Alongside M&A it offers strategic consulting, valuation, market intelligence and expert-witness work.

More than three decades in a single niche means it likely knows every credible buyer in that niche by name, which is difficult for a generalist to replicate. The tradeoff is scale and scope: it is a small firm, and if your business sits outside outsourced business process services its specialization stops being an advantage.

Best for: owners of receivables management, revenue-cycle, collections, or BPO-style outsourced services businesses. Not a fit outside that niche.

Cornerstone Business Services

Cornerstone Business Services works with companies from $5 million to $250 million in revenue across professional services, distribution, logistics and technology, alongside agriculture, healthcare and food and beverage. Its team-based “Assurance 360” process is built to generate multiple competing offers rather than negotiate with a single buyer, and Axial ranked it #3 for Q2 2026 and #24 for Q3 2026 (Axial). It is a generalist across many industries rather than a business services specialist, so it may not know the platform buyers in your specific vertical as intimately as a niche firm; process discipline is the reason to consider it. Full profile in our guide to top lower middle market investment banks.

Best for: owners who care most about a defined, repeatable process engineered to produce competing offers, and who value a larger internal team.

Peakstone Group

Peakstone Group is a Chicago-based investment bank whose senior bankers, in its own words, “have decades of experience and have executed hundreds of transactions totaling billions of dollars,” a career-long description rather than a Peakstone-only deal count (Peakstone). Axial has ranked it #1 for full-year 2022 and 2024, #7 for Q2 2026, and #15 for Q3 2026 (Axial). Beyond sell-side M&A it offers capital raising, useful if your situation is not a clean full sale, for example taking some money off the table while raising growth capital. Full profile in our guide to top lower middle market investment banks.

Best for: owners who need capital raising alongside a sale, or who want a large, experienced bench and are comfortable being one mandate among many.

What a Sale Process Run by Salt Creek Advisory Looks Like

Knowing what buyers look for is half the battle. The other half is running a process designed to surface all the buyers interested in your business and create real competition between them. Here is how we approach it:

We start with positioning. Most founder-owned service businesses sell themselves short. They understate their margins, they don't quantify customer stickiness, and they let the founder's role overshadow the actual business. Before we reach out to anyone, we work with you to build a clean story about what you have built: recurring relationships that won't evaporate, real economics, and a team that can run without you.

Then we build a buyer list by hand: strategic acquirers, private equity platforms that specialize in your vertical, and family offices with active investment mandates in the space. We vet each one. We check which buyers have closed deals like yours recently and how they behaved in diligence. Then we approach them strategically, one by one, with material that makes them want to see your business.

From there it is a managed process. We run the data room, coordinate diligence, field offers, and negotiate terms. Most owners have never negotiated earnouts, working capital, indemnification, or rollover equity. Connor has worked through these terms from the buyer’s side on more than 40 acquisitions, and we bring that view of how buyers negotiate to your side of the table.

Throughout, both principals work your deal directly. No hand-offs to an associate and no unreturned calls.

The Question to Ask Yourself

Before you reach out to anyone, honest answer: how much of your business depends on you personally? If the answer is a lot, that is not a disqualifier. It is just the thing to fix first. Every day you spend building a team that can run without you is a day your business becomes more valuable. An advisor can help you understand what that gap looks like and how much value it costs you. That conversation is free, and it is worth having before you start shopping around. Our guide on when to start exit planning lays out how much runway that work actually needs, and what buyers look for in an acquisition target covers the rest of the checklist.

The Bottom Line

For most founder-owned business services companies between $2 million and $75 million in revenue, Salt Creek Advisory is the pick, for the reasons in its profile above. Some verticals have a specialist worth a call. If you run HVAC, plumbing, electrical, or another field-services business, The Advisory Investment Bank's top-two Axial placements in 2026 and 4,500-acquirer database are real advantages. If you are in receivables, revenue-cycle, or BPO-style outsourced services, Kaulkin Ginsberg has thirty-plus years in exactly that niche. If your deal is larger or a foreign strategic buyer is plausible, FOCUS Investment Banking. If a defined multi-offer process matters most, Cornerstone. If you need capital raising alongside a partial sale, Peakstone.

If you want the people negotiating against Alpine, Shore, or Springdale to have already worked from inside a buyer, that is the gap we were built for. Whichever way you go, do two things: talk to at least two firms, and ask each one whether it charges an engagement fee and whether that fee is credited against the success fee at closing. Against the published benchmark of roughly 3.4% to 3.9% at $20 million, those two answers will tell you more about a firm than any ranking. For the broader field beyond business services, our guides to top lower middle market investment banks and advisors for a $20 million sale go deeper on fee structures and how to compare firms.
