Criteria for Evaluating Business Worth: The Financial, Operational, Strategic and Risk Filters I Use to Value Every Acquisition

The criteria for evaluating business worth in an acquisition fall into four categories: financial value criteria (SDE, EBITDA, free cash flow, DCF), operational value criteria (management team, systems, IP, customer base), strategic value criteria (market position, growth runway, competitive moat), and risk-adjusted value criteria (DSCR ≥1.5x, customer concentration, revenue quality). A defensible valuation triangulates all four — not one number from one method. If the four sets don’t converge within a 20% range, you don’t have a valuation yet, you have a guess.

Look, this page is not “how to filter deals from a broker list.” That’s screening criteria and it’s a different job. This is the criteria I use when a deal is already on my desk and I have to answer the only question that matters: what is this business actually worth, and what would I pay for it?

I’ve closed 300+ acquisitions over 30 years. Every one of them lived or died on the valuation work I did in the two weeks after the seller sent me the numbers. Get the criteria right and you buy at 3x with $30K down. Get them wrong and you pay 6x, sign a personal guarantee, and spend three years wondering why your DSCR keeps slipping. Here are the exact filters I run, in the order I run them.

Financial Value Criteria: SDE, EBITDA, Cash Flow, DCF

Financial value criteria measure what the business earns after normalization. The core four are Seller’s Discretionary Earnings (SDE) for businesses under $1M in profit, EBITDA for businesses above it, free cash flow after real capex and working capital, and a Discounted Cash Flow (DCF) model as the sanity check. Every valuation starts here because everything else is a modifier on this number.

The sequence I run on every deal:

1. Normalize SDE or EBITDA first. Strip out one-time items, add back excess owner compensation, remove personal expenses running through the P&L (country club, kid’s car, the wife’s “consulting fee”). This gives you the true earning power the business will hand to a new owner. Most sellers overstate SDE by 15-30% — rebuild it from the tax return yourself.
2. Apply a comparable transactions multiple. For SDE-scale businesses (under $1M), 2-3.5x is the working range. For EBITDA-scale ($1M-$5M), 4-6x. Above $5M EBITDA, 6-9x. Pull recent transaction comps from BizBuySell, IBBA, or a broker in the sector — not asking-price data, actual closed deals.
3. Cross-check with free cash flow. EBITDA is not cash. Subtract real maintenance capex, working capital growth, and taxes to get free cash flow. If FCF is less than 60% of EBITDA, the multiple has to come down or the deal doesn’t service the debt.
4. Run a DCF as the sanity check. Project 5 years of FCF, discount at 15-20% (your required return, not the risk-free rate), add a terminal value at a conservative exit multiple. If the DCF number is more than 25% below your multiple-based number, one of your assumptions is wrong.
5. Triangulate. You should have three numbers now — SDE/EBITDA multiple, FCF-adjusted multiple, and DCF. They should cluster inside a 20% band. That band is your valuation range. The bottom is your opening offer.

Operational Value Criteria: Team, Systems, IP, Customers

Operational value criteria measure whether the earnings you just calculated will still be there 12 months after close. A business with the same EBITDA can be worth double or half of another depending on the operational bones underneath. These are the criteria that separate a business you can own from a job you just bought.

The five operational filters, in order of impact:

1. Management team depth. Is there a real number-two? Someone who can run operations without the seller in the building? Owner-operator businesses trade 2-3 turns lower than owner-investor businesses because the earnings walk out the door with the seller. If there’s no team, either negotiate a longer transition or discount the multiple by 30%.
2. Documented systems and SOPs. Are the processes written down or in the seller’s head? A business with a documented SOP library is transferrable. One without is a liability. This alone can move the multiple by half a turn either direction.
3. Intellectual property and defensibility. Trademarks, patents, proprietary software, exclusive supplier contracts, protected recipes, licensed territories. IP-backed cash flow deserves a premium multiple. Undifferentiated cash flow trades at the low end of the range.
4. Customer base quality. No customer over 15% of revenue. Customer tenure of 3+ years on the top 20. Recurring or contracted revenue over 40% of the total. Concentration risk kills valuations — lenders discount for it, buyers discount for it, and I discount for it.
5. Physical asset condition. Are the trucks, equipment, and facilities going to need $500K of deferred capex in year one? Walk the assets. What you see with your own eyes changes the offer.

Strategic Value Criteria: Position, Growth, Moat

Strategic value criteria measure what the business could be worth to a future buyer, not what it’s worth today. Businesses with strategic value get bid up by strategic acquirers and PE roll-ups — that premium is where the real returns hide. Ignore this layer and you’re valuing the business only for its current owner, not for its next one.

The three strategic filters:

1. Market position. Top 3 in a defined geography or niche? Named on RFPs by default? Referenced by trade press? Category leadership — even in a small category — attracts strategic buyers who will pay 1-2 turns above financial value to buy market share instead of building it.
2. Growth runway. Is the addressable market growing? Are there adjacent products, geographies, or bolt-on targets? A business at $1M EBITDA in a shrinking niche is worth less than a business at $1M EBITDA with a clear path to $3M. Buyers pay for the runway, not just the number.
3. Competitive moat. Regulatory license, exclusive dealer agreement, network effects, switching costs, brand recognition, technical patent. A moat means the earnings are defensible against a competitor showing up next Tuesday. No moat, no premium.

Every strategic factor that is real and durable adds 0.5-1.5 turns to the exit multiple. That’s how a business you buy at 3x becomes a business you sell at 6x.

Risk-Adjusted Value Criteria: DSCR, Concentration, Revenue Quality

Risk-adjusted value criteria bring the number back down to what a bank will lend on and what you can safely operate. Any valuation that doesn’t survive the risk filter is a paper number — not a real number you can transact on. This is where deals actually close or blow up.

The four risk criteria I never skip:

1. DSCR at 1.5x or higher. Debt Service Coverage Ratio = post-close free cash flow divided by annual debt service (principal + interest). Below 1.5x, the lender won’t fund and the deal will suffocate the first time revenue dips. If DSCR pencils at 1.3x, you’re either paying too much or borrowing too much — fix one or walk.
2. Customer concentration. Top customer under 15% of revenue. Top 5 under 40%. Above those thresholds, discount the valuation by 15-25% because a single account loss can wipe out the DSCR.
3. Revenue quality. Recurring beats project. Contracted beats spot. Multi-year beats one-time. A business with 60% recurring revenue should carry a 30-50% valuation premium over the same business running on transactional sales.
4. Working capital adequacy. Deal price plus enough working capital to fund 90 days of operations plus growth. Undercapitalized deals kill more acquisitions than bad purchase prices — you buy the business, then starve it, then lose it.

How the Four Criteria Sets Combine into One Valuation

Financial gives you the range. Operational tells you where in the range. Strategic tells you whether to reach for the top of the range. Risk tells you whether the number survives contact with a bank and a downturn.

Worked example. Landscaping business, $850K SDE, family owned 22 years.

• Financial: $850K SDE x 2.75x = $2.34M. FCF check passes. DCF at 18% comes in at $2.2M. Range: $2.1M-$2.4M.
• Operational: Full-time GM already in place, SOPs documented, top 20 customers avg 8-year tenure. Push toward the top of the range.
• Strategic: #2 in a growing suburban market, roll-up target for a regional PE-backed platform. Add 0.5 turns of exit potential to the thesis.
• Risk: No customer over 8%. 45% recurring maintenance contracts. DSCR at 1.7x on a $250K down / seller-financed structure. Passes.

Offer: $2.35M with $250K down, $1.85M seller note over 6 years at 7%, $250K SBA working capital. That’s what a real valuation gets you — a defensible number and a structure your seller will actually sign.

What Kills a Valuation Every Time

• Using the seller’s stated SDE. Rebuild it from the tax return. Every time.
• Applying a generic multiple. Pull actual comps in the sector and size band. “5x EBITDA” is not a valuation, it’s a slogan.
• Ignoring capex. If it takes $200K a year in capex to maintain the earnings, EBITDA overstates value by exactly that.
• Skipping the DSCR test. If the deal doesn’t cover 1.5x, the deal doesn’t close — or worse, it closes and then implodes.
• Falling in love. The valuation is the valuation. If the seller won’t meet you inside the range, walk. There’s another deal on Monday.

Frequently Asked Questions

What are the main criteria for evaluating business worth in an acquisition?

The main criteria fall into four sets: financial (normalized SDE or EBITDA, free cash flow, DCF, comparable transaction multiples), operational (management team, documented systems, IP, customer base quality, asset condition), strategic (market position, growth runway, competitive moat) and risk-adjusted (DSCR at 1.5x or higher, customer concentration, revenue quality, working capital adequacy). A defensible valuation triangulates across all four sets rather than relying on any single method.

How do you value a small business for acquisition?

Start by normalizing Seller’s Discretionary Earnings (SDE) from the last three years of tax returns, adding back excess owner compensation and personal expenses. Apply a comparable transaction multiple for the sector — typically 2-3.5x SDE for businesses under $1M in profit. Cross-check with a free cash flow calculation net of capex and working capital, then run a DCF at your required return (15-20%). The three numbers should land within a 20% band — that band is your valuation range.

What are the key metrics to consider when valuing a business for a potential acquisition?

The core valuation metrics are normalized SDE or EBITDA, free cash flow after capex, revenue growth rate, gross and EBITDA margins, customer concentration (top account share of revenue), recurring revenue percentage, DSCR at the proposed debt structure, and comparable transaction multiples in the sector and size band. Cash flow metrics matter more than accounting metrics because they determine what the business can service in debt and distribute to the owner.

What SDE or EBITDA multiple should I use to value a business for acquisition?

Multiples depend on size, sector, and quality. Under $1M in SDE typically trades at 2-3.5x. Businesses at $1M-$3M EBITDA trade at 4-6x. $3M-$5M EBITDA trades at 5-7x. Above $5M EBITDA, 6-9x is common. Recurring-revenue businesses, businesses with a management team in place, and businesses in growing sectors sit at the top of the range. Owner-dependent businesses, concentrated customer bases, and shrinking niches sit at the bottom.

How do you evaluate a company for acquisition beyond the financials?

Beyond the numbers, evaluate operational transferability (is there a real team, are the systems documented, will the earnings survive the seller leaving?), strategic value (market position, growth runway, competitive moat) and risk (customer concentration, revenue quality, working capital needs). Two businesses with identical EBITDA can be worth double or half of one another depending on how these non-financial criteria score. Non-financial criteria are what create exit multiple expansion.

How does DCF work for a small business acquisition?

Project 5 years of free cash flow using base-case operational assumptions, discount each year back to present value at your required rate of return (typically 15-20% for lower middle market deals, higher for riskier businesses), then add a terminal value calculated at a conservative exit multiple. Sum those present values to get the DCF valuation. Use DCF as a sanity check on your multiple-based number, not as the primary method — comparable transactions carry more weight in this size band.

What DSCR do I need for a business acquisition to be safe?

A Debt Service Coverage Ratio of 1.5x or higher is the safe threshold and the level most SBA and commercial lenders require. That means the post-close free cash flow of the business must exceed the annual principal and interest payments by at least 50%. Anything less and a routine revenue dip puts the deal into default — either restructure the debt, lower the purchase price, or increase the down payment until DSCR clears 1.5x.

How do I handle customer concentration when valuing a business?

Concentration reduces valuation. No single customer should exceed 15% of revenue and the top 5 should stay under 40%. Above those thresholds, discount the valuation by 15-25% and require customer retention warranties or an earn-out tied to top-customer retention. A concentrated customer base doesn’t disqualify a deal, but it changes both the price you pay and the structure you use to protect against loss of the concentration risk.

Where can I learn to apply these valuation criteria on real deals?

Dealmaker Academy walks the four-criteria valuation framework on live acquisition targets with Carl Allen and the coaching team, including SDE normalization, comparable transactions, DCF modeling, and structuring around DSCR. The Protégé Community is where active dealmakers post the valuations they’re running and get feedback from operators who’ve closed the same size deal.

Next move: take the last deal you looked at and rebuild the SDE from the tax return yourself. Then run the four-criteria valuation on it before you talk to the seller again. See the other evaluation frameworks we use, or book a coaching call to walk the four criteria on a specific target.
