What Private Equity Firms Look for When Acquiring a Small Business

Private equity firms run structured acquisition processes. They know what they’re looking for, and they know how to find out whether you have it. Sellers who understand the criteria in advance can position their business to pass the screen — and sellers who don’t often find themselves surprised by deal-killing due diligence findings that could have been addressed months earlier.

Here is how PE firms actually evaluate acquisitions, from initial screen to final offer.

The initial screen: what gets a meeting

Before any detailed conversation, PE firms apply a quick filter. The criteria vary by firm and strategy, but the common elements are:

Earnings threshold. Most PE add-on buyers are looking for $500K minimum in SDE or EBITDA. Below that, the overhead of a full institutional due diligence process doesn’t make economic sense. Platform acquisitions — the first deal in a new market — typically require $2M+ EBITDA.

Industry fit. PE firms acquire in defined verticals. An HVAC platform isn’t looking at dental practices. Knowing which firms are actively acquiring in your specific industry — and which are in the right stage of their fund lifecycle to still be buying — is essential for targeting the right buyers.

Geography. Roll-up strategies are typically built around regional density. A PE firm with a dozen HVAC acquisitions in the Southeast is more interested in your Georgia HVAC company than your Nevada one, regardless of business quality.

Clean history. Major legal judgments, regulatory violations, environmental issues, or significant customer disputes surface in initial background research and can end the conversation before it starts.

If a business passes the initial screen, it earns a more detailed look. That’s where the real evaluation begins.

The six factors PE firms score in depth

1. Earnings quality

“Earnings quality” is PE’s term for how reliable and repeatable the income is. They’re not just looking at the top-line SDE number — they’re asking: will this number still be here in three years?

High-quality earnings have these characteristics:

• Recurring or repeat revenue — customers who return without new sales effort
• Diversified customer base — no single customer above 15% of revenue
• Growing over time — consistent or improving trend over 3 years
• Not dependent on a single person — the owner, a star salesperson, or a key technician

Low-quality earnings — one-time projects, relationship-driven revenue that leaves with the owner, revenue concentrated in a single client — get discounted heavily in PE valuation models.

2. Financials and add-back documentation

PE firms will conduct a quality of earnings (QoE) analysis during due diligence — a rigorous independent review of every line item in your financials. The things they’re looking for:

• Three years of P&L statements that reconcile with tax returns and bank statements
• Add-backs (owner salary above market, personal vehicle, one-time expenses) that are clearly documented and defensible
• No significant revenue or expense items that appear only in some years without explanation
• Payroll records that match reported labor costs
• Accounts receivable aging that confirms reported revenue was actually collected

The QoE doesn’t just verify the numbers — it establishes the buyer’s confidence in you as a seller. Financials that hold up to scrutiny build trust. Financials that don’t generate price reductions or terminated deals.

3. Owner dependence

This is the most common deal-complicating issue in small business PE acquisitions. PE firms are buying a business they will operate without you. If the business only works because of your presence, relationships, or judgment — it’s not what they thought they were buying.

They probe owner dependence systematically:

• Revenue relationships: Are customers loyal to the business or to you personally? Would they stay if you left?
• Operational functions: What would stop working on day 31 if you were gone? Dispatch? Supplier relationships? Technical decisions?
• Employee management: Does the team function without you directing daily activities?
• Financial management: Are you the only person who understands the P&L?

Businesses that demonstrate documented systems, a functional management layer, and customers who engage with the brand rather than the owner are significantly more attractive — and command materially higher multiples.

4. Revenue defensibility

PE buyers are modeling your business’s earnings four to seven years in the future. They need confidence that the revenue will still be there. The questions they ask:

• Contracts: Are customer relationships documented, or relationship-only?
• Market position: Are you one of the dominant players in your market, or easily displaced by competition?
• Competitive moat: Is there something — licensing, geographic exclusivity, technology, brand — that makes it hard for customers to switch?
• Churn rate: What percentage of customers don’t return, and why?

Businesses with membership plans, service agreements, long-term customer relationships, and documented market share have the easiest time satisfying this criteria.

5. Team and operations

PE integration assumes your team stays. What they need to know:

• Key employees: Who are the critical people, and are they at flight risk? Technicians with specific certifications, a general manager who runs operations, a dispatcher who knows all the customers — these people matter.
• Compensation: Are key employees paid at or above market? Below-market compensation is a liability — PE firms will have to remedy it, and they factor that cost into the offer.
• Documented processes: Are operational procedures written down, or in the owner’s head? Can a new owner or general manager follow how the business runs?
• Software and systems: Is the business running modern scheduling, dispatch, and customer management tools, or on spreadsheets and phone calls?

6. Integration readiness

Finally, PE buyers assess how hard it will be to integrate your business into their platform. This is particularly relevant in roll-up acquisitions, where integration velocity matters to the platform’s overall returns.

Businesses that are already running software compatible with the platform’s systems, that have documented processes, and whose owner is willing to stay on for 12–24 months to facilitate the transition integrate faster and at lower cost — which is reflected in the offer price.

The practical implication: start now

The most actionable insight from this list is that most of these factors take 12–24 months to improve. A business that has had an email retention system running for 6 months and a maintenance plan program for 8 months is not telling the same story as one that has had both for 2 years. Clean books can be assembled in 90 days; a 3-year track record of reconcilable financials requires 3 years.

If a PE exit is a plausible goal for you in the next two to five years, the time to start preparing is now — not when you’ve decided to sell.

I work with sellers across multiple industries to identify and address the gaps that PE firms find in due diligence, and to connect qualified businesses with the right buyers at the right time. If you want to understand where you stand against this criteria, let’s talk.
