A sales due diligence checklist for mid-market PE

A sales due diligence checklist ensures no part of the revenue engine is missed under deal pressure. This is the structure we use to assess whether a mid-market business can deliver its growth plan.

In one line

Five areas, one question each: can this company build pipeline, convert it, keep customers, and scale the team that does it?

How to use it

Treat each area as a hypothesis to disprove. The goal is not to tick boxes but to find the two or three things that would genuinely put the plan at risk — and to size the upside where the engine is stronger than the price implies.

The five areas

01 · Pipeline & forecasting
  • Coverage against target and quality of pipeline
  • Forecast accuracy and the discipline behind it
  • Stage definitions, conversion and velocity
02 · Methodology & conversion
  • A repeatable sales motion vs. hero selling
  • Win/loss patterns and sales-cycle length
  • Deal qualification and discounting behaviour
03 · Acquisition & channels
  • Channel mix and cost to acquire
  • Lead sources and their reliability
  • Payback and unit economics
04 · Retention & account growth
  • Gross and net retention
  • Churn drivers and early-warning signals
  • Expansion and cross-sell motion
05 · People, incentives & tooling
  • Leadership, capacity and ramp
  • Incentive design and its behaviours
  • CRM hygiene and the data you can trust

From checklist to plan

A checklist finds the issues; a plan fixes them. The output of a good sales DD is not a scorecard but a prioritised set of workstreams — the beginnings of a value creation plan.

A note on scope. This guide reflects how Altius Partners approaches sales due diligence for private equity as of 2026. Every engagement is tailored to the specific value thesis, sector and timetable, and this is not a substitute for transaction-specific advice.

Frequently asked questions

What is sales due diligence?

A pre-deal assessment of the ability of a company to sell — pipeline, methodology, acquisition, retention, team and tooling — to test whether the sales plan behind the model is real.

What does a sales DD cover?

Typically five areas: pipeline and forecasting, methodology and conversion, acquisition and channels, retention and account growth, and people, incentives and tooling.

What are the biggest red flags?

Revenue concentrated in a few reps, chronic forecast misses, heavy quarter-end discounting, churn masked by new logos, and an untrustworthy CRM.

Who should run it?

Senior operators who have built and scaled sales functions themselves — at Altius, two senior experts per mandate, no juniors.
