How should private equity sponsors evaluate quality of sales during commercial due diligence?

To evaluate Quality of Sales, private equity firms must look beyond revenue durability and pipeline size. They must audit the underlying marketing and sales infrastructure, talent, and management systems to determine if forecasted organic growth is repeatable, controllable, and capable of converting into EBITDA.

TL;DR

• Go beyond the bridge slide. Scrutinize customer concentration and the over-reliance on repeat business. A high percentage of revenue from existing customers often signals an inability to acquire new logos, putting the growth thesis at risk.
• Interrogate the pipeline. Most industrial sales pipelines are full of unqualified opportunities that aren't qualified against a robust opportunity qualification scorecard. Assess deal velocity, conversion rates, and the source of deals. Distinguish between teams that "find projects" (late-stage, low-win-rate) and those that "create projects" (early-stage, vision-shaping).
• Evaluate the human capital. The biggest risk is often the sales leader and the team. Assess whether they have the business acumen to sell outcomes to executives, not just product specs to engineers. Look for patterns of chronic underperformance (40-60% of reps missing quota and 40-60% of deals ending in "no decision" are systemic failures, not an individual one).
• Audit the sales infrastructure. Look for a defined sales process, a consistent methodology, and a management coaching (with substantial role-playing) cadence. The absence of this infrastructure means growth is based on individual heroics, which is neither scalable nor predictable.
• Assess pricing discipline and margin integrity. Understand how pricing is set, how discounting is managed, and whether the sales team is equipped to defend value. Gross margin contribution is a critical indicator of sales quality.

Commercial due diligence in the middle-market industrial space is a well-understood exercise. We check for customer concentration, we look at historical growth, and we build a bridge slide that gets us to the pro forma revenue number.

The problem is that this analysis confirms what happened, but it rarely explains how or why. It validates the past without providing any real conviction about the future.

For private equity sponsors whose investment thesis depends on organic growth through new logo acquisition, this is a critical blind spot. The Quality of Sales isn't just about the durability of the current revenue stream. It's about the existence of a scalable engine capable of executing the value creation plan. Most of the time, that engine is either missing or broken.

Here’s a better framework for evaluating what’s really going on.

The Illusion of Revenue Durability

The typical finding presented in diligence is almost always customer retention. Management will point to the fact that 70% of revenue comes from repeat customers as a sign of a strong, defensible business with a loyal base.

We should see this for what it often is: a red flag.

This isn't a story of loyalty. It's a story of an organization that cannot reliably win new business. The sales team, and the entire commercial motion, is optimized for account maintenance, not new logo acquisition. They are farmers. The value creation plan, however, is likely built on ferocious hunting and growth in market share.

Examples of questions to ask:

• What percentage of revenue in the last 24 months came from net new logos?
• What is the average tenure of the top 20 customers? 
• What is the revenue growth or decline within that tenured customer base (reasonable LTV assumption)? Are you growing with them or being slowly engineered out?

A business that can't win new customers isn't durable. It's slowly liquidating.

Is the Pipeline an Asset or a Poison Pill?

Next, you’ll be shown the pipeline report. It will look big. It is almost always a work of fiction.

In most industrial companies we analyze, the pipeline is a collection of vaguely qualified hopes and dreams. Reps are incentivized to pack it with anything that moves to signal activity particularly when their KPIs include pipeline contribution and quotes issued. Management, lacking a rigorous process, has no way to challenge it.

The deeper issue is how this pipeline is being generated. Most industrial sales reps are taught to "find projects." They call around asking, "Got anything coming up?" By the time a project is active, a short list has already been built, and research from firms like 6sense shows the eventual winner is already on it 70% of the time. This is a game you are statistically destined to lose.

Great sales teams don't "find projects." They "create projects" by engaging executives early, shaping their buying vision, and defining the problem in a way that leads directly to their solution.

• What are the defined stages of the sales process, and what verifiable outcomes are required to advance a deal? (If you get a blank stare, there is no process).
• What is the typical win rate on quoted business? What percentage of deals end in "no decision"? (A high "no decision" rate, often 40-60%, means reps can't build a business case for change).
• Where do most opportunities originate? Are they reactive responses to RFPs or proactive engagements driven by the sales team?
• What are the key milestones and quantitative and qualitative criteria in your opportunity qualification process?
• What % of opportunities get qualified OUT in a typical month?
• What is the forecast accuracy?

An inflated pipeline can be worse than an empty one. It gives a false sense of security and hides fundamental flaws in your go-to-market motion.

The Sales Team: Built for the Past or the Future?

The biggest variable in any value creation plan is human capital. And in industrial sales, the talent model is profoundly broken. We consistently see that 40 to 60% of sales reps chronically miss quota. This isn't an individual performance issue. It's a systemic hiring and management failure.

Companies default to hiring for two things: industry experience and a good referral. Both are terrible predictors of success.

This leads to the dreaded two-year churn cycle. A new sales leader is hired based on their resume at a larger competitor. They arrive, but often lack the skills to build the missing sales infrastructure (process, methodology, coaching) assuming those are in place as they have been in previous roles. After 18-24 months of flat results and unmet expectations, they’re exited. The company then uses the exact same flawed criteria to hire their replacement, restarting the clock and burning through the hold period.

This recurring failure stems from broken hiring processes. I see this pattern consume years of a value creation timeline. A structured approach to Sales Talent Hiring & Recruiting is essential to break this cycle. It moves beyond flawed proxies to evaluate candidates on the actual competencies required to win complex industrial deals: the ability to sell business outcomes to the C-suite, the skill to coach and manage a team, and the discipline to build a scalable process from scratch.

Sample questions to ask:

• What is the documented, repeatable process for hiring sales reps and sales leaders?
• Does the sales hiring process incorporate an empirical, predictively accurate, sales-specific assessment?
• What percentage of the current sales team has hit quota in each of the last eight quarters?
• Does the sales leader spend their time coaching reps and reviewing pipeline, or are they the "super rep" who personally closes all the big deals?
• What is the formal sales onboarding process?
• What % of sales hires exceed expectations within one year?

Your growth model is entirely dependent on a team that may not have the DNA to execute it.

The Operations vs. Sales Double Standard

Here is the great irony of manufacturing. A PE-backed company will have Six Sigma black belts walking the factory floor, obsessing over a 1% improvement in OEE. They would never tolerate a 40% defect rate in production.

Then they walk over to the sales department and accept a 50% quota miss rate as the cost of doing business.

This tolerance for failure exists because most industrial organizations lack the most basic sales infrastructure. There is no sales process, no sales methodology, no funnel modeling, and no meaningful management cadence. Sales is treated as an art, not a science. Growth is unpredictable because the process is undefined.

Examples of questions to ask:

• Is there a sales playbook that defines the process, methodology, playbook, opportunity qualification scorecard, consistent coaching built around role-playing, effective CRM, adoption of AI, and other sales enablement tools for the team?
• Has the company modeled its sales funnel? Do they know the activity levels, conversion rates, and deal velocity required to hit the revenue target? How are conversion rates used to guide coaching and track improvement?
• What does a weekly pipeline review look like? Is it a rigorous deal inspection or a simple forecast roll-up?

Without this infrastructure, you are not buying a revenue engine. You are buying a collection of individual territories, and your ability to influence the outcome is effectively zero.
