What does operational due diligence actually cover?

Financial diligence tests the numbers. Commercial diligence tests the market. Operational diligence tests whether the business can deliver the plan, and where the cost base leaks. Here is what a proper one covers.

Most mid-market deals get financial diligence, legal diligence, and some form of commercial review. Operational diligence is often lighter, done late, or folded into a management presentation. That is a mistake, because the operating cost base is where the value creation plan will succeed or fail.

The question it answers

Financial diligence asks: are the numbers real? Commercial diligence asks: will the market support the plan? Operational diligence asks: can this business actually execute, and what is it spending that it does not need to?

That second half is where most of the recoverable value sits in a mid-market business. Not headcount. Contracts.

What a proper review covers

Vendor and contract base. Every material supplier agreement: term, renewal mechanics, pricing structure, escalation clauses, exit rights. In most businesses that have not been through a sponsor before, a meaningful share of these were signed years ago and never revisited. That is addressable cost, and it should be sized in the deal model.

Technology spend. Software licenses, cloud infrastructure, IT services. License counts against headcount. Cloud commitments against actual workloads. Support contracts against what is actually used. This is where acquisitive businesses leak most, because each acquisition brought its own stack and nobody consolidated.

Marketing and agency effectiveness. Agency contracts, fee structures, media transparency, production costs. Marketing is often the largest discretionary budget in the business and the least commercially governed. In diligence, we look at whether the spend is buying growth or activity.

Procurement maturity. Is there a function, a process, and an owner? Or does every department buy what it wants? The answer tells you how fast savings can be captured post-close and how much of the improvement will stick.

Revenue operations. Pipeline hygiene, forecast accuracy, CRM data quality, sales and marketing handoff. If the growth plan depends on the sales engine and the sales engine cannot forecast within 20%, the plan is at risk.

Management reporting. How long does it take to close the month? How much of the board pack is assembled by hand? Slow, manual reporting is a leading indicator of a business that will struggle to run a 100-day plan.

What the output should look like

Not a report. A set of deal model inputs: addressable savings by category, risk-adjusted, with a timeline for capture. Plus a draft 100-day plan, so that Day One is a start, not a planning exercise.

Done this way, operational diligence pays for itself several times over before close, because it changes the price, the plan, or both.

When to do it

Earlier than you think. The findings are most valuable while price and structure are still open. A two to three week review during the exclusivity period is usually enough for a mid-market business, provided the data room is reasonably complete.
