Commercial Due Diligence
Commercial Due Diligence the process by which buyers assess the market fundamentals, competitive dynamics, and customer quality underlying a target company's business.
While financial due diligence looks backward at historical performance, commercial due diligence looks forward to determine whether the market and competitive landscape will support future growth.

How Commercial Due Diligence Works
Commercial due diligence evaluates whether a company's growth story holds up under scrutiny. Buyers commission this workstream to validate the investment thesis, particularly around market size, competitive positioning, and customer sustainability. For private equity buyers, this is critical because they're not just buying today's cash flow—they're betting on growth over a 3-7 year hold period.
The scope typically covers market analysis (TAM, SAM, growth drivers, structural shifts), competitive positioning (market share, differentiation, barriers to entry), customer analysis (concentration, retention, satisfaction, reference calls), and commercial operations (go-to-market strategy, sales effectiveness, pricing power).
A formal commercial due diligence report synthesizes these findings into a comprehensive assessment, often using a traffic light summary: green items validate the thesis, yellow items require attention, and red items raise serious concerns. As a seller, you won't see this report—but you'll feel its effects in how aggressively buyers bid and what issues they raise in final negotiations.
Key Points
- •Validates the buyer's investment thesis by testing market and growth assumptions
- •Includes direct customer reference calls—typically 8-15 for lower middle market deals
- •Examines market size, competitive positioning, customer quality, and commercial scalability
- •Findings directly influence valuation multiples and deal terms
- •Discrepancies between seller claims and market reality can reprice or kill deals
Why Sellers Should Care About Commercial Diligence
Commercial due diligence is technically a buyer-side activity—they commission the report, pay the consultants, and use the findings to inform their investment decision. So why should sellers care? Because your answers will be tested. Everything in your CIM makes claims about market position, competitive advantage, and customer relationships. Commercial diligence is where those claims get verified or refuted.
We've seen deals repriced or killed because commercial diligence found material discrepancies between what sellers claimed and what the market reality showed. A buyer who discovers that your 'market leadership' is actually a 12% share in a fragmented market, or that your 'sticky customer relationships' are actually at-risk contracts with competitors circling, won't just accept the original terms.
Common Scenarios We See:
- •Customer calls revealing lukewarm satisfaction or active competitor evaluation
- •Market share claims that don't hold up under third-party research
- •Growth projections unsupported by market dynamics or competitive position
- •Customer concentration risk discovered through reference calls
- •Competitive advantages that prove easily replicable
What Sellers Should Know:
Before entering a sale process, know what your key customers would say if asked. Consider having preliminary conversations to gauge sentiment and, where appropriate, to prepare them for potential buyer outreach. Customers who feel blindsided by diligence calls often react negatively to learning the company is for sale.
