Due diligence

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.

Valuation

What Should You Expect to Pay?

3x-5x

SDE

Owner-operated, project-based revenue

5x-9x

EBITDA

Licensed team, repeat clients, strong pipeline

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.

What drives a premium

Multiple licensed professional engineers who will stay after the sale, covering several states

70%+ of revenue from repeat clients on ongoing agreements, not competitive bids

Signed pipeline of awarded contracts providing forward revenue visibility

Project managers who handle delivery and client relationships independently of the owner

Architectural & Engineering Services Business Acquisition

Start with the licensed staff: how many PEs, which states, and how long they've been at the firm. Then look at client retention, asking what percentage of revenue comes from repeat clients on standing agreements versus one-off competitive bids. A firm with a strong licensed team and 70%+ repeat revenue is a very different acquisition from one built around the owner's personal relationships. Browse engineering businesses for sale on Rejigg.
Most engineering firms sell for 3 to 9 times annual profit. Owner-operated firms trading on personal relationships typically fall in the 3 to 5x SDE range. Firms with licensed staff across multiple states, strong repeat revenue, and a working pipeline can reach 5 to 9x EBITDA. Use the SBA loan calculator to see how different deal sizes look on a monthly payment basis.
Start with three years of financials broken out by client type (government, municipal, private industrial) and project type. Then ask for a staff list with PE licenses and tenure. Get a pipeline summary showing signed work, active proposals, and win rates. Talk to two or three long-term clients if you can. The combination of licensed staff stability and client retention rate will tell you more than any single number.
Key questions to start with: How many licensed PEs are on staff and in which states? How long has each one been with the firm? What percentage of revenue comes from clients who have been with the firm three or more years? What's the signed pipeline value and expected timeline? Who handles project management and client relationships if the owner steps back? Are any government on-call contracts up for renewal soon? What certifications does the firm hold and when do they expire?
Rejigg lists engineering firms that have been individually sourced and vetted. You can browse engineering businesses for sale on Rejigg and connect directly with owners. Listings include financial and staff details so you can quickly assess fit.
Firm-level licenses generally require notifying the relevant state board when ownership changes, and some states require a new qualifying professional on record. The key is having multiple licensed engineers on staff so the firm's ability to stamp and approve work doesn't depend on one person. Before closing, confirm each PE's license status and ask if they've agreed to stay. Having a staff retention plan in place before diligence starts signals a well-prepared seller.
Buyers understand that engineering revenue comes from projects. What they're paying for is the predictability within that model. A firm that wins 70% of proposals from clients who have been coming back for a decade is far more predictable than one dependent on competitive bids with new clients. Show what percentage of clients rebook year over year, what standing agreements look like, and how deep the pipeline is. That context turns project-based revenue from a concern into a strength.
