Research & Methodology
The Academic Basis

The DealFax Framework:
Evidence and methodology.

The six focus areas and 30 dimensions in the DealFax operational readiness framework are not proprietary inventions. They are drawn from established academic research on M&A transaction dynamics, practitioner literature from the IBBA and AM&AA, and publicly available datasets from the Bureau of Labor Statistics, U.S. Census Bureau, and OSHA. This page documents the evidence basis for each area of assessment.

The Framework
Design Principles

Three data layers. One structured picture.

A DealFax assessment draws from three independent sources. Each layer contributes something the other two cannot provide alone. The goal is a scored picture that is grounded in documented evidence and external context — not solely in what the owner reports about their own business.

The three data layers
1
Industry benchmarking
BLS workforce data, Census SUSB industry growth rates, and category-level Google reputation averages provide the context that makes a business's own numbers meaningful. A 14% annual turnover rate means something different for a specialty trade contractor in a tight labor market than for a professional services firm. The relevant benchmark is pulled for the specific NAICS code and geography — not a generic average.
2
Compliance verification
OSHA establishment records, state licensing databases, Secretary of State records, and DOL wage enforcement data are checked independently against the specific business — in whichever state it operates. This layer confirms whether the compliance and licensing picture matches what the owner represents, and surfaces anything not visible from financial statements.
3
Operational assessment
A structured interview and document review covers the internal picture — team structure, client relationships, documentation quality, systems infrastructure, and succession depth. Owner-provided information is the starting point. Evidence requirements determine how each dimension scores. Self-reporting alone cannot achieve the higher score levels.
How the benchmarking works

When a business is engaged, DealFax identifies its NAICS code, firm size class (by employee count and revenue band), and primary geographic market. These three parameters are used to pull the relevant cut from each dataset — so a 28-person HVAC contractor in a Northern Virginia county gets benchmarks specific to specialty trade contractors of that size in that labor market, not a national HVAC industry average. This specificity is the core of what makes DealFax benchmarks actionable rather than generic. The full data stack — all 16 named sources, what each provides, and which dimensions each informs — is documented in the Data Stack section below →

The scoring scale

1.0–2.0
Not Ready
Significant gaps in multiple areas. Operational risks likely to affect deal structure and viability.
2.0–3.0
Conditionally Ready
A deal is possible but operational deficiencies typically result in earnouts, holdbacks, or extended consulting requirements.
3.0–4.0
Transaction-Ready
Operational profile supports the transaction. Reduced basis for discounts or conditions attached to the deal.
4.0–5.0
Premium-Ready
Institutional-quality operations. Strong position for competitive buyer interest and favorable deal terms.
Six Focus Areas
Evidence Basis

Why these six areas.
What the research says.

The six focus areas reflect operational dimensions that are documented in M&A practitioner literature and academic research as factors that affect how transactions are structured and priced in owner-operated lower-middle market businesses. Each area also maps to at least one publicly available dataset that provides an independent benchmark.

Area 01 · 7 dimensions · 58 indicators
Owner Dependency
Owner dependency — the concentration of relationships, authority, and institutional knowledge in a single person — is identified as a primary valuation risk factor across IBBA Market Pulse data and academic M&A literature. Graebner (2009) documents how seller-dependent knowledge transfer shapes acquisition outcomes and introduces trust asymmetries that affect deal structure.
Graebner, Academy of Management Journal, 52(3), 2009; IBBA Market Pulse, Q4 2023
Area 02 · 6 dimensions · 55 indicators
Revenue Quality
Customer concentration risk is a standard diligence item in lower-middle market M&A. The SBA's credit policy guidelines treat customer concentration above 25% as a material risk factor for loan approval — the same logic applies in transaction diligence. IBBA Market Pulse data tracks earnout frequency against revenue concentration findings.
SBA Standard Operating Procedure 50-10-6; IBBA Market Pulse, 2023–2024
Area 03 · 5 dimensions · 50 indicators
Operational Systems
DePamphilis (2022) identifies operational documentation and systems infrastructure as a core component of operational due diligence in acquisitions. Verifiable, accessible records are a standard expectation in any structured diligence process. The absence of cloud-based accounting or field management systems is a documented source of pricing adjustments in service business transactions.
DePamphilis, Mergers, Acquisitions, and Other Restructuring Activities, 10th ed., 2022
Area 04 · 5 dimensions · 47 indicators
Workforce Stability
BLS Job Openings and Labor Turnover Survey (JOLTS) provides sector-level turnover benchmarks by NAICS code. Comparison against industry averages identifies whether a business's attrition is within normal range or represents an elevated retention risk — one that commonly results in retention bonuses or workforce conditions attached to the transaction.
BLS JOLTS, NAICS 238 (Specialty Trade Contractors), 2023
Area 05 · 4 dimensions · 45 indicators
Customer Health
Online reputation data (Google ratings, review volume, velocity) is increasingly used as an independent proxy for customer loyalty and demand trajectory. BizBuySell Insight Reports and practitioner literature from AM&AA document the growing inclusion of reputation metrics in lower-middle market operational diligence.
BizBuySell Insight Report, 2024; AM&AA practitioner guidelines
Area 06 · 3 dimensions · 45 indicators
Succession & Mgmt.
IBBA Market Pulse data consistently identifies the absence of a management layer below the owner as a leading cause of extended seller consulting requirements and earnout imposition. The Exit Planning Institute's State of Owner Readiness (2023) documents that the majority of owners have no written succession or exit plan at the time they begin considering a sale.

The Data Stack
16 Named Sources

Every public dataset DealFax pulls.
What it provides. What it informs.

This is the canonical reference for the DealFax data enrichment and benchmarking process. Every Assessed Report draws from 16 named public sources across three categories — industry benchmarking, reputation signals, and compliance verification. The key principle: benchmarks are pulled for the specific NAICS code, firm size class, and geography of the business being assessed. Not national averages. Not generic sector data. The benchmark that applies to a 28-person HVAC contractor in a mid-size metro is different from the one that applies to a 5-person IT services firm in a rural county — and DealFax is built to make that distinction.

Category 1 — Industry Benchmarking (8 datasets)

These datasets provide the external context that makes a business's own operational numbers meaningful. They are not records about the specific business — they are the relevant backdrop for the industry, size class, and geography the business operates in. Without this layer, a metric is just a number. Against the right benchmark, it's a signal.

Category 2 — Reputation Signals (4 sources)

Reputation data provides an independently verifiable, buyer-facing signal about the health of the customer base that cannot be gamed or self-reported. Google is the primary benchmark source due to its volume and consistency across all industries and geographies. The others are used selectively based on the business's sector and coverage availability.

SourceWhat It ProvidesHow It's UsedDimensions Informed
Google Maps / PlacesStar rating, review count, and review velocity for the business and comparable competitors in the same NAICS category and geographic area.Primary reputation benchmark across all industries. The business's rating and review trajectory is benchmarked against the average for comparable businesses in the same category and local geography.D-26 Google Rating vs. Market Average, D-27 Review Volume & Velocity
Better Business Bureau (BBB)Accreditation status, complaint history, complaint resolution pattern, and BBB rating.Trust and compliance signal. Used to identify unresolved complaint patterns or regulatory concerns not visible in financial records. Not used as a primary rating benchmark.D-27 Review Velocity (supplementary), general compliance signal
Angi / HomeAdvisorRating, review count, and pro status for home services trade businesses.Secondary reputation benchmark for home services trades — HVAC, plumbing, electrical, general contracting. Used where Angi coverage is meaningful and adds context beyond Google alone.D-26 Google Rating vs. Market Average (supplementary for trades)
YelpStar rating and review volume for businesses with active Yelp presence.Supplementary reputation signal for professional services, food and hospitality, and health services where Yelp coverage is stronger. Not used as a primary benchmark for trades businesses where coverage is thin.D-26, D-27 (supplementary where coverage is sufficient)

Category 3 — Compliance Verification (4 databases)

These are records about the specific business — not benchmarks or industry context. Each is checked independently against the business's legal name, license numbers, or employer identification. The applicable state licensing databases are identified as part of scope definition and pulled for wherever the business operates — this is a national process, not a Virginia or Maryland-specific one.

DatabaseSourceWhat It VerifiesDimensions Informed
OSHA Establishment-Specific Injury & Illness DataU.S. Department of Labor — OSHAReported workplace injuries, illness rates, and citations for the specific establishment.

Seller Readiness
The TRUST Index

Measuring seller readiness independently of business readiness.

The TRUST Index is a five-dimension assessor-observed evaluation of the seller's own readiness to drive a successful transition — independent of the business's operational score. It addresses a gap in standard operational due diligence: a business can be operationally ready while the seller is not, and vice versa.

The TRUST Index is not self-reported. Scores are assigned by the assessor based on observed behavior, document evidence, and interview responses. Three design principles prevent gaming. First, each dimension must be assessor-observed — the owner cannot self-report a high score. Second, documentary evidence is required to reach the upper score levels — without it, the score is capped at a defined ceiling regardless of what the owner says. Third, the most critical dimensions are cross-referenced against independently verifiable sources, so discrepancies between what the owner represents and what the record shows are surfaced during the assessment.

DimensionWhat It MeasuresEvidence Required for High Score
Transparency & ResponsivenessSeller's cooperation with the assessment process — document provision, response completeness, and accuracy of information providedTimely document delivery; no material omissions identified in cross-reference against public records
Knowledge Transfer ReadinessExtent to which institutional knowledge has been documented or delegated prior to the assessmentSOPs, org chart, documented client introduction plan; evidence of delegation in place
Commitment to ExitClarity and conviction of the seller's exit timeline and readiness to execute a transition within a defined windowDocumented exit timeline; no evidence of ambivalence or undisclosed contingencies that would affect timing
Relationship Introduction WillingnessWhether key client and vendor relationships have been introduced to a successor or documented for transferEvidence of relationship introduction; documented contacts independent of owner's personal network
Post-Close Transition SupportSeller's demonstrated willingness and practical ability to support post-close operations during the transition periodDocumented availability commitment, defined consulting scope, timeline clarity, no conflicts with other obligations

The TRUST Index classification scale: 1.0–2.0 = Unprepared Seller; 2.0–3.0 = Engaged but Unprepared; 3.0–4.0 = Transition-Ready Seller; 4.0–5.0 = Optimally Positioned.
