Due diligence
What to Look For
Practical guidance from hundreds of real acquisition conversations.
Recurring vs. Project Revenue
- Ask the seller to break out what percentage of revenue renews automatically versus what has to be re-won each cycle.
- Retainer clients, annual contracts, and subscription-based engagements are worth more than one-time project work because they're predictable from day one.
- A firm where 50 percent or more of revenue is contracted and recurring is a strong starting point for your evaluation.
Who Owns the Client Relationships
- Ask for a list of clients with their assigned team member and how long each relationship has been managed that way.
- If every key client calls the founder when something goes wrong, that means real transition work for you and some client risk worth getting comfortable with early.
- Senior staff who have managed client accounts independently for years are what turn a services firm into a real asset.
Credentials and Licensing
- Ask which licenses or credentials are required for the business to operate and whether those are held by the owner or spread across the team.
- In auditing, engineering, and land management, a firm with multiple licensed professionals beyond the founder is in a much stronger position at transition.
- If the owner's departure would create a credentialing gap, that's worth understanding early and building into your plan.
Client Concentration
- Ask for a revenue breakdown by client and how long each major relationship has been active.
- Firms with five or more long-tenured clients each under 20 percent of revenue give you real resilience.
- The length of a client relationship often matters as much as the size when you're thinking about how durable the revenue is.
Documented Processes
- Ask whether the firm runs on documented workflows, project templates, and playbooks, or whether expertise primarily lives in people's heads.
- Firms with structured processes retain their value through an ownership transition much more reliably than those where everything is informal.
- Whether it's audit checklists, HR platform configurations, or engineering project templates, good documentation tells you the business can run without you recreating it from scratch.
