The PE Operating Partner's Guide to Technical Due Diligence

Technical due diligence for acquisitions should focus on whether the target's systems can plug into the platform's operating model without creating hidden integration costs.

If this symptom is showing up every week, treat it as an operating constraint, not a content topic. The cost is usually sitting in manual hours, delayed decisions, billing friction, or reporting doubt.

Technical due diligence for acquisitions should focus on whether the target's systems can plug into the platform's operating model without creating hidden integration costs.

Systems inventory: What to ask for

Request a complete list of systems: CRM, dispatch, billing, accounting, reporting, custom tools, spreadsheets, and integrations. Include vendor names, contract terms, and user counts. Also ask about shadow systems: tools or processes that the team relies on but are not officially managed.

Workflow mapping: Follow the money

Trace the customer-to-cash workflow. How does a lead become a customer? How does a job get scheduled, completed, invoiced, and paid? Where are the manual handoffs? The goal is to understand whether the target's workflow can align with the platform's without massive redesign.

Data quality assessment

Bad data is expensive to fix. Sample customer records, job histories, and financial data. Look for duplicates, missing fields, inconsistent formats, and orphan records. Ask how the target handles data exceptions and whether there is a data governance process.

Integration cost estimation

Estimate the cost of integrating the target's systems into the platform. Include data migration, workflow alignment, reporting consolidation, and training. Add a contingency for shadow systems and undocumented workarounds that surface after close.

If the problem is recurring, treat it as a systems problem before adding more manual process around it.

Frequently asked questions

Should technical due diligence include code review?

Only if the target has significant custom software. For most operations companies, the relevant technical assessment is workflow design, data quality, and integration architecture—not code quality.

How do we evaluate data quality quickly?

Sample 100-200 records from each core system. Check for completeness, consistency, and duplicates. Ask the target's team about their data cleanup processes and exception rates.

What red flags should kill a deal?

Rarely does technical debt kill a deal by itself. But it should affect valuation and integration planning. Major red flags include: unrecoverable data corruption, critical systems running on unsupported technology, and no documentation of workflow logic.

If this sounds familiar, let's find the root cause.
