Commercial Due Diligence for Life Science Tools and Diagnostics Companies
What commercial due diligence covers, what buyers examine in a tools or diagnostics company, where value is lost before a deal closes, and a checklist of the evidence a buyer will ask for.

1. What commercial due diligence is
Commercial due diligence is the part of a transaction review that tests whether a company's revenue plan is believable. It looks at the market, the customers and the commercial organization, and asks whether the growth in the plan is likely to happen.
It's different from financial due diligence, although the two are often run together. Financial due diligence confirms that the historical numbers are accurate. Commercial due diligence asks whether those numbers will repeat and grow after the deal closes.
Most commercial due diligence concentrates on the market: its size, growth, competitors and the company's share. That work matters, but it often spends less time on the commercial engine itself, meaning how the company forecasts, builds pipeline, sells, and keeps its customers. In tools and diagnostics, that is usually where the risk sits.
2. How it affects the price
Enterprise value is a multiple times a metric. The metric is last year's revenue or EBITDA, and the multiple reflects how confident the buyer is that it will repeat and grow. Commercial due diligence is where that confidence is tested.
Strong commercial execution rarely earns a premium multiple on its own. However, weak execution reliably produces a discount, and that discount is usually visible about 18 months before an exit. Buyers start from a market reference multiple and subtract turns for risks they can document.
The five discounts that commercial due diligence most often uncovers are:
- Comparable set: revenue mix and consumable pull-through place the company with lower-multiple peers.
- Underwriting: past forecasts have not matched actuals, so the buyer underwrites a lower number than management's plan.
- Repeatability: growth depends on a few people or a few accounts.
- Transition: revenue is at risk if a key leader leaves after the deal.
- Structure: the buyer moves part of the price into earn-outs and holdbacks to cover what it cannot verify.

3. The four questions buyers ask
Whatever the format of the review, a buyer looking at the commercial engine is trying to answer four questions. CommEx calls these the Predictability Quadrant.
01
Forecast
Have commits matched actuals, quarter after quarter?
02
Pipeline
Does the pipeline hold up when someone outside the sales team inspects it?
03
Execution
Is selling a repeatable system, or does it depend on a few strong individuals?
04
Coverage
Is territory and account coverage planned, or did it happen by luck?

4. What is different in tools and diagnostics
Most tools and diagnostics companies sell on a razor and razorblade model. A $50,000 instrument can generate more than $200,000 in lifetime consumables, so a placement is only the start of the revenue, and the value of the business depends on what happens after it.
That's why a buyer should look at three separate measures rather than one revenue forecast:
- Instrument (capital) forecast: deal-driven and tied to customer budget cycles, so it is naturally uneven.
- Consumable (recurring) forecast: driven by utilization and pull-through per placed instrument.
- Customer retention: net revenue retention, attach rate and the share of the installed base that has gone dormant.
When these are combined into one number, a strong capital quarter can hide a falling consumable run rate. A buyer who separates them will find it, so it's better for management to find it first.
5. A commercial due diligence checklist
These are the documents and data a buyer will typically ask for when reviewing the commercial engine of a tools or diagnostics company. Each item is something that can be produced and checked, not an opinion.
Forecast and pipeline
- Forecast versus actual by quarter for the last eight quarters, split into instrument and consumable revenue
- The written definition of each forecast category (commit, best case, pipeline)
- Pipeline snapshots at the start of each quarter, with stage history
- Close-date slip history and the share of opportunities with past-due close dates
- Documented stage exit criteria and the qualification method in use
Sales execution and coverage
- Quota attainment by rep for the last two years
- Share of new bookings from the top three reps
- Win and loss records with reasons
- Rep tenure, ramp time and turnover
- Territory and account assignments, with the method used to set them
Customers and installed base
- Installed base list with placement date and consumable revenue per instrument
- Dormant instruments and how dormancy is defined
- Gross and net revenue retention by customer cohort
- Revenue share of the top ten customers
- Pricing and discount history by product
Operations and governance
- CRM field completeness for open opportunities
- The commercial meeting calendar (forecast calls, pipeline reviews, quarterly business reviews)
- The commercial KPI report leadership reviews, with a sample
- The commercial systems in use and how they connect
- Commercial roles, reporting lines and key-person dependencies
6. When to do it
Commercial due diligence is usually thought of as something a buyer does during a deal. The same review is useful at three points, and it is most valuable at the first.
About 18 months before a sale
Sell-side readiness
Management and the board find the gaps a buyer would find, while there is still time to fix them and show several quarters of improved results.
During a transaction
Buy-side review
An investor tests the revenue plan against the evidence and adjusts the price or structure to reflect what can and cannot be verified.
After close
Value creation baseline
The new owner scores the commercial engine at the start of the hold period and re-scores it later to check whether execution has improved.
7. How CommEx assesses the commercial engine
The Commercial Readiness Assessment (CRA) is a 42-statement diagnostic completed independently by up to five leaders, typically the CEO and the heads of sales, marketing, customer success and finance or commercial operations. Each statement is rated 1 to 5 against written descriptions of each level.
The statements cover the nine pillars of the Commercial Operating System©, and the results are weighted into the Commercial Readiness Index (CRI©), a score from 0 to 100. The report also shows a pillar heatmap, a ranked list of gaps, the places where leaders disagree, and a 90-day plan.
Because the CRA produces a number rather than a narrative, it can be compared before and after a deal, or across companies in a portfolio.

8. Case studies
Two examples from NanoString Technologies, where Chad led the commercial organization from 2017 to 2022.
Case study · Consumables
nCounter: consumable channel turnaround
Product and service revenue growth went from 4% in 2017 to 29% in 2021, and revenue doubled to $144.0 million, after every account was given one owner and consumable sales into the installed base were rebuilt.
Case study · Launch
GeoMx: spatial biology commercial launch
A spatial biology platform taken from paid sample testing on prototypes in 2017 to about 255 installed systems and $51.9 million in revenue in 2021, beating initial guidance in each of its first 3 years.
9. Frequently asked questions
What is commercial due diligence?
It is the part of a transaction review that tests whether a company's revenue plan is believable, by examining its market, its customers and its commercial organization.
How is it different from financial due diligence?
Financial due diligence confirms that the historical numbers are accurate. Commercial due diligence asks whether those numbers will repeat and grow after the deal.
Does this replace a market study?
No. A market study tests whether the opportunity is real. A review of the commercial engine tests whether the company can capture it. Most deals benefit from both.
How accurate should a sales forecast be?
In our experience, forecast variance above 15 percent is usually the leading indicator of a deeper execution problem. The first step is for leadership to agree on one definition of forecast accuracy.
Can management run this before a sale?
Yes, and that is when it is most useful. A sell-side review about 18 months ahead leaves time to fix the gaps and show several quarters of results before a buyer looks.
Talk through a commercial review
If you're preparing a tools or diagnostics company for sale, evaluating one, or starting a hold period, a 30-minute call is a good place to start.
