Due Diligence KPIs: The Numbers I Pull on Every Acquisition Target Before I Write an Offer

Due diligence KPIs are the specific quantitative metrics — with defined thresholds — that a dealmaker pulls from a target company’s financials, operations, customer base, team, and market during acquisition diligence to score risk and set the offer. They fall into five families: financial KPIs (DSCR, EBITDA margin, working-capital ratio, revenue quality), operational KPIs (owner hours, gross margin trend, capex intensity), customer KPIs (concentration percentage, retention rate, net revenue retention), team KPIs (turnover, tenure, bench depth), and market KPIs (category growth, share trend, price realization). Each KPI has a pass, watch, or walk threshold, and the composite score decides whether you buy, reprice, or walk.

I’ve done 300+ deals over 30 years. Every deal I’ve closed on and made money on hit the same KPI thresholds. Every deal I’ve watched go sideways missed the same ones. KPIs are not corporate-strategy busywork — they are the pre-transaction scoreboard that tells you whether the story the seller is telling you actually matches the numbers underneath it.

Here’s the exact KPI checklist I run on every target, with the pass/watch/walk thresholds, in the order I pull them. It’s the same framework we drill inside Dealmaker Academy.

KPIs vs. Red Flags vs. Risk Assessment: What This Page Covers

KPIs are the metrics themselves — the numbers. Red flags are what fires when a KPI misses. Risk assessment is how the flags roll up into a decision. Different jobs, different pages.

• This page — the specific KPIs to pull on every target, with the thresholds that separate a bankable business from a pass.
• Acquisition red flags — the warning signs that fire when the KPIs miss.
• Business acquisition risk assessment — the 7-category scoring framework that turns KPIs and flags into a buy/walk/restructure decision.

Read this one when you’re staring at a data room and need to know which numbers to pull first and what “good” looks like for each one.

Financial KPIs: The Numbers That Decide Whether the Business Is Bankable

Financial KPIs measure whether the target generates enough real, sustainable cash flow to service acquisition debt and clear your required return. These are the numbers your lender will re-verify, so pull them first and pull them clean.

The seven financial KPIs I score on every deal, with the pass/watch/walk thresholds:

• Debt Service Coverage Ratio (DSCR). Trailing 12-month EBITDA divided by projected annual debt service. Pass: 1.5x or higher. Watch: 1.25x–1.5x. Walk: under 1.25x. This is the single most important number in an acquisition — miss it and the deal is not bankable at any price.
• EBITDA margin. Pass depends on the industry — 15%+ for services, 10%+ for distribution, 8%+ for manufacturing. Watch is 3 points below industry median. Walk is a margin that has compressed three years in a row.
• Revenue quality (recurring vs. one-time). Pass: 50%+ recurring or contracted. Watch: 25–50%. Walk: under 25% with declining trend. Recurring revenue trades at 3–4x the multiple of one-time revenue, so this KPI directly drives price.
• Working capital ratio. Current assets divided by current liabilities. Pass: 1.5x or higher and stable. Watch: 1.0x–1.5x. Walk: under 1.0x, or a downward trend in the trailing four quarters (that’s the seller stripping cash pre-close).
• Gross margin trend. Pull five years. Pass: flat or expanding. Watch: contracting under 2 points per year. Walk: contracting over 2 points per year — revenue growth on shrinking margin is the seller buying revenue to stage the sale.
• Add-back ratio. Owner add-backs to reported EBITDA. Pass: under 10%. Watch: 10–15%. Walk: over 15% without a Quality of Earnings report backing each line. Aggressive add-backs are how “adjusted EBITDA” becomes fiction.
• AR aging past 90 days. Pass: under 5% of receivables. Watch: 5–10%. Walk: over 10%. Either the customers are slow-paying (a collection issue you inherit) or the revenue was booked but never earned.

Operational KPIs: What the Business Looks Like the Day You Take the Keys

Operational KPIs measure whether you’re buying a business or buying yourself a job — how dependent the machine is on the current owner, and how much capex the machine is quietly deferring. These are the numbers that decide whether reported earnings actually survive after close.

The five operational KPIs I check on every walkthrough:

• Owner hours per week in the business. Pass: under 20. Watch: 20–40. Walk: 40+. Every hour over 20 is a job you now have to fill — subtract the market cost of that role from earnings before you value the deal.
• Documented SOP coverage. Percentage of core processes with written, current SOPs. Pass: 80%+. Watch: 50–80%. Walk: under 50%. “We just do it that way” costs six figures to unwind once the seller is gone.
• Capex intensity. Trailing 3-year average capex divided by revenue. Compare to industry benchmark. Pass: at or above benchmark. Watch: 20–40% below. Walk: 40%+ below — that’s deferred maintenance you’re inheriting, and it hits your cash flow in month one.
• System age and support status. Core ERP, POS, and financial systems still supported by vendor. Pass: yes across the board. Watch: one system past end-of-life. Walk: multiple systems past end-of-life or custom-built by a contractor who’s gone.
• Single-point-of-failure count. Number of critical dependencies on one machine, one truck, one server, or one vendor. Pass: zero. Watch: one, with a mitigation plan. Walk: two or more.

Customer KPIs: The Ceiling the Market Puts on the Deal

Customer KPIs measure whether the revenue base is diversified, sticky, and growing — or whether one bad conversation with one customer breaks the entire model. The best financials in the world don’t survive customer concentration, and this is the KPI family most first-time buyers underweight.

The five customer KPIs I pull on every target:

• Customer concentration. Largest customer as a percentage of revenue. Pass: under 10%. Watch: 10–15%. Walk: over 15% without a customer-retention earnout in the deal structure. Above 25%, value the business as if that customer is already gone.
• Top-10 customer concentration. Top 10 customers as a percentage of revenue. Pass: under 40%. Watch: 40–60%. Walk: over 60%. Concentration compounds — one large customer plus a few medium ones is the same risk profile.
• Customer retention rate. Percentage of prior-year customers still active this year. Pass: 90%+. Watch: 80–90%. Walk: under 80%. Retention is the single best proxy for whether the product actually solves a real problem.
• Net revenue retention (for recurring-revenue businesses). Revenue from existing cohort this year vs. same cohort last year. Pass: 100%+. Watch: 85–100%. Walk: under 85%. Below 100% means the cohort is shrinking — you’re buying a leaky bucket.
• Customer acquisition cost payback. Months of gross margin to recover the cost of acquiring a customer. Pass: under 12 months. Watch: 12–24. Walk: over 24 months — the growth engine is subsidized and unprofitable.

Team KPIs: Who Stays, Who Leaves, and What That Costs You

Team KPIs measure whether the people who actually run the business will still be running it 90 days after close. On paper you’re buying a business. In practice you’re buying a group of people and their opinion of what happens next.

The four team KPIs I score on every deal:

• Voluntary turnover, trailing 24 months. Pass: at or below industry average. Watch: 1.5x industry average. Walk: 2x+ industry average, or a step-change spike in the last 12 months. Ex-employees on LinkedIn will tell you the story the seller won’t.
• Key-employee tenure. Average tenure of the top 5 operators. Pass: 5+ years. Watch: 2–5 years. Walk: under 2 years, or a recent departure at the top of the org.
• Bench depth. Number of roles with an identified internal successor. Pass: every C-level and department-lead role. Watch: gaps at department-lead level. Walk: no succession plan for the owner’s role — that’s a red flag disguised as a KPI.
• Retention agreement coverage pre-close. Percentage of key employees under signed retention agreements before close. Pass: 100% of top 5. Watch: partial. Walk: none — half of them will be gone within 90 days of the announcement.

Market KPIs: Whether the Outside World Lets the Deal Work

Market KPIs measure whether the industry itself is a tailwind or a headwind on your ownership. A great business in a shrinking market is still a bad deal, and this is the KPI family that separates dealmakers from operators.

The four market KPIs I pull for every target:

• Category growth rate, trailing 3 years. Pass: 3%+ annualized. Watch: 0–3%. Walk: negative — you’re buying yesterday.
• Market share trend. Target’s share of the served market over 3 years. Pass: flat or growing. Watch: losing 1–2 points per year. Walk: losing more than 2 points — someone is out-executing the incumbent.
• Price realization. Average selling price change vs. cost inflation. Pass: pricing keeping up with or ahead of costs. Watch: within 2 points of cost inflation. Walk: pricing below cost inflation — the seller has lost pricing power and you’ll inherit that.
• Platform dependency. Percentage of revenue routed through a single distribution channel (Amazon, one distributor, one referral source). Pass: under 20%. Watch: 20–40%. Walk: over 40% — the platform can change terms overnight and the model doesn’t survive it.

How to Identify Which KPIs Matter for a Specific Deal in 5 Steps

Every target has a KPI story. The framework tells you which numbers to pull; the deal tells you which ones to weight.

1. Get three years of tax returns, P&Ls, and bank statements. Reconcile them against each other before you pull a single KPI. If the three don’t tie, the KPIs computed on top of them are fiction.
2. Compute the financial KPIs first. DSCR, EBITDA margin, revenue quality, working capital, gross margin trend, add-back ratio, AR aging. If two or more walk-threshold flags fire here, stop — the deal isn’t bankable.
3. Pull operational and customer KPIs on-site. Owner hours, SOP coverage, capex intensity, customer concentration, retention. These are the numbers the CIM will lie about the most. Verify on the floor and with actual customers under NDA.
4. Benchmark against industry. IBISWorld, trade publications, association reports. A 12% EBITDA margin is a pass in distribution and a walk in software. Context sets the threshold.
5. Score the composite and translate to action. Total pass/watch/walk counts across all five families. Zero walks and mostly passes: move fast. Any walk: reprice or restructure. Multiple walks: pass. Never argue a walk into a pass because the seller is charming.

The KPI Scorecard: Turning Numbers Into a Decision

Every KPI collapses into one of three verdicts: pass, watch, or walk. Roll them up and you have your decision.

• All pass: High-confidence deal. Move fast — someone else will spot it too.
• Mostly pass, a few watches: Bankable. Structure the watches as monitoring covenants, retention agreements, or transition milestones.
• Any walk-threshold KPI, but only one: Reprice or restructure. Every walk becomes a term — an earnout, an indemnity, an escrow, a customer-retention holdback. If the seller won’t accept the structure the walk KPI requires, that IS the answer.
• Two or more walks, or DSCR under 1.25x: Pass. No structure fixes a business that doesn’t cover its own debt or a fundamentally broken model.

KPIs Feed Terms, Not Arguments

The best dealmakers don’t argue KPIs with the seller. They translate them into terms. A weak retention KPI justifies a customer-retention earnout. A high customer concentration KPI justifies a holdback tied to that customer. A shaky DSCR justifies more seller financing. Aggressive add-backs justify a full Quality of Earnings paid for by the seller. Every KPI miss becomes a clause.

A seller-financed deal at 90% of asking with a 5-year note and covenants tied to your walk-threshold KPIs beats an all-cash deal at 70% of asking every day of the week — because the terms carry the risk with the deal, not against your equity.

Frequently Asked Questions

What are the most important KPIs to identify during due diligence?

The seven financial KPIs — DSCR, EBITDA margin, revenue quality, working capital ratio, gross margin trend, add-back ratio, and AR aging — are the non-negotiables. Below those, customer concentration, customer retention, owner hours, and voluntary turnover carry the most weight for pre-transaction decision-making. DSCR under 1.25x or customer concentration above 25% without a retention earnout are single-KPI walks by themselves.

How do you identify KPIs specific to an acquisition target?

Start with the universal financial KPIs — DSCR, EBITDA margin, revenue quality, working capital, gross margin trend, add-back ratio, and AR aging — which apply to every deal. Layer on operational, customer, team, and market KPIs weighted to the target’s business model: recurring-revenue businesses need net revenue retention, service businesses need utilization and billable rate, distribution needs inventory turns. Benchmark every KPI against industry median before setting the pass/watch/walk threshold.

What is a good DSCR for a business acquisition?

A debt service coverage ratio of 1.5x or higher is the minimum threshold for a bankable acquisition. 1.25x to 1.5x is watch — the deal works only with a lower purchase price or more seller financing. Below 1.25x is a walk in every category — the business isn’t generating enough cash to safely cover debt service plus your required return.

How much customer concentration is a walk-threshold KPI?

Above 15% of revenue to a single customer, concentration becomes a walk unless the deal structure includes a customer-retention earnout. Above 25%, value the deal as if that customer is already gone. Top-10 concentration above 60% is a walk on its own — concentration compounds, and one large customer plus a few medium ones is the same risk profile as one dominant customer.

What KPIs signal that a target is really an owner-operator job in disguise?

Owner working 40+ hours per week, SOP coverage under 50%, single-point-of-failure count above one, and no identified successor for the owner’s role. Any two of those together mean you’re buying a job, not an investment. Subtract the market cost of the owner’s role from reported earnings before you value the deal, and re-run every financial KPI on the adjusted number.

How often should acquisition KPIs be measured post-close?

Monthly for the first 12 months, quarterly thereafter. Track the exact same KPIs you scored pre-close so you can see which ones held and which slipped. The gap between your pre-close projection and the trailing 12-month post-close actual is your integration scorecard.

What is the difference between due diligence KPIs and post-acquisition KPIs?

Due diligence KPIs are decision inputs — they tell you whether to buy, at what price, and with what structure. Post-acquisition KPIs are performance inputs — they tell you whether the business is executing to the thesis. Same underlying metrics in most cases, but different jobs: one sets the offer, the other measures the operator.

Which KPIs are hardest for sellers to inflate?

Bank-statement cash flow, DSCR computed against actual proposed debt service, AR aging past 90 days, customer retention verified by ex-customer interviews, and voluntary turnover pulled from HRIS records. Sellers can shape reported EBITDA with add-backs and shape reported revenue with channel-stuffing, but the bank statements, aging reports, retention data, and HR records tell the truth.

Where can dealmakers learn to compute and interpret KPIs on live deals?

Dealmaker Academy walks the KPI scorecard on real acquisition targets with Carl Allen and the coaching team. The Protégé Community is where active dealmakers share the KPI scores they’re computing on live deals and get another set of eyes before they issue an LOI. Both are built for people running deals, not people reading about them.
