# What Is CDD (Commercial Due Diligence)?

> Commercial due diligence (CDD) is third-party research on a target company's market, customers, and competitive position — validating revenue quality and growth assumptions before an investor or acquirer closes a deal.

**CDD (commercial due diligence)** is independent analysis of a company's market, customers, competition, and growth thesis — typically commissioned by buyers or investors before a major transaction.

### How it works

Specialist firms (consultancies, sector experts) run CDD parallel to financial, legal, and technical diligence. Workstreams include:

- **Market sizing and growth drivers** — independent TAM/SAM sanity checks
- **Customer interviews** — satisfaction, renewal intent, pricing power
- **Competitive landscape** — win/loss patterns, differentiation durability
- **Commercial model review** — pipeline quality, churn, sales efficiency

Output is a report with risks, opportunities, and sometimes purchase-price implications. On [buyout](/glossary/buyout) and large growth equity deals, CDD is standard; on early venture rounds, investors often perform lighter internal commercial diligence.

Founders in exit processes should curate reference customers and document churn cohorts before CDD calls begin — surprises in customer interviews move terms fast.

CDD timelines often run two to four weeks on mid-market deals, running parallel to QoE and legal diligence. Findings can reprice the LOI or kill the transaction if customer concentration or market shrinkage exceeds underwriting tolerance.

### Why it matters

- **Founders:** Treat CDD as a sales process to future owners. One unhappy flagship customer can dominate the narrative.
- **Investors:** CDD validates whether EBITDA or ARR growth is structurally sound or a cyclical spike.

### Common mistake

Confusing CDD with financial audit. CDD answers "will customers keep buying?" — not whether revenue was booked correctly (though related).

## FAQ

### What is CDD in simple terms?

Before buying or investing big, sponsors hire consultants to interview customers, size the market, and stress-test whether growth claims hold — separate from financial and legal diligence.

### Why does CDD matter?

For founders selling a company, weak CDD findings reduce price or kill deals. For investors, CDD catches inflated TAM slides and customer concentration risks that spreadsheets miss.
