Sales due diligence (sales DD) assesses a company's ability to sell — its pipeline, conversion, retention, team and revenue operations. Commercial due diligence (CDD) assesses the market it sells into. They answer different questions, and the sharpest investment cases use both.
CDD validates the opportunity. Sales DD validates the machine that has to capture it.
Commercial due diligence is an outside-in exercise. It validates the market and the top line of the model:
What it is not designed to do is look inside the company and judge whether its commercial function can actually deliver against that market.
Sales due diligence is an inside-out exercise. It assesses the revenue engine itself:
| Commercial DD | Sales DD | |
|---|---|---|
| Core question | Is the market attractive? | Can the company sell into it? |
| Vantage point | Outside-in | Inside-out |
| Typical evidence | Market data, expert & customer interviews | CRM & pipeline data, commercial KPIs, team review |
| Risk it catches | A weak or shrinking market | A plan the sales engine can't deliver |
| Best used | To confirm the opportunity | To confirm — and plan — its capture |
Sales DD is one part of a broader GTM due diligence. GTM DD takes the same inside-out lens but widens it beyond sales to include proposition and pricing, go-to-market strategy, marketing and demand generation, and the commercial operating model — the full revenue engine, not just the sales team.
Sales DD is the deep-dive on the selling motion. GTM DD is the end-to-end assessment of everything that turns a proposition into recurring revenue — sales included.
A CDD and a GTM/sales DD together give an investment committee both halves of the picture: the size of the prize, and an operator-tested view of how it gets captured. Run in parallel, they also reinforce each other — the market view sharpens the questions asked of the revenue engine, and vice versa.
Commercial DD assesses the market from the outside in — size, growth, competition and demand. Sales DD assesses the company from the inside out — whether its pipeline, conversion, retention and team can deliver the plan.
No — they answer different questions and are complementary. The strongest cases run both, or a GTM DD alongside a CDD.
Sales DD is one component of a GTM DD. GTM DD adds proposition and pricing, go-to-market strategy, demand generation and the commercial operating model.
A focused sales or GTM DD is typically delivered in two to four weeks, aligned to the deal timetable.
