What to Look For
Practical guidance from hundreds of real acquisition conversations.
Licensed Engineers on Staff
- Ask how many licensed professional engineers are on staff, which states they're licensed in, and how long each has been with the firm.
- A firm with multiple PEs across several states keeps its ability to stamp and approve work after the sale without depending on the owner.
- Find out whether any licenses are held personally by the current owner and what the transfer implications are.
- Engineers who manage their own client relationships and stay through the transition are what make the business fundable.
Repeat Client Revenue
- Ask what percentage of revenue comes from clients who have been returning for three or more years.
- Government on-call contracts and multi-year private agreements carry predictability that competitive bid work doesn't.
- If 70 percent or more of revenue is from repeat clients, the existing relationships carry most of the business forward on their own.
Pipeline Visibility
- Ask for a pipeline summary with expected values and timelines for signed work and live proposals.
- Awarded contracts and proposals in late stages give you a window into near-term revenue that financial statements alone can't show.
- A win rate history on competitive bids tells you how well the firm converts without relying on the owner's personal network.
Operations Without the Owner
- Find out who handles project scheduling, client communication, and day-to-day delivery when the owner is out.
- If a principal engineer and project managers run the business independently, you can step in without managing every technical detail.
- If the owner is still the lead engineer on most projects, the transition plan becomes a bigger part of the deal structure.

Multiples are driven by how much of the revenue is genuinely recurring from repeat clients and how independent the licensed team is, because both factors directly determine how much value survives an ownership transition.
