Due diligence
What to Look For
Practical guidance from hundreds of real acquisition conversations.
Client Concentration
Worth understanding what percentage of revenue comes from the top three clients. If one client represents more than 25% of revenue, that's something you'd want to get comfortable with and model out before making an offer. On the flip side, firms with five or more clients each under 15% of revenue give you real resilience during the ownership transition.
Retainer vs. Project Revenue
This is one of the most exciting things to dig into. Ask the seller to break out how much revenue comes from recurring monthly or annual retainers versus one-time project work. Retainer revenue is worth significantly more because it's predictable. A firm doing $500K/year where 60% is retainer-based gives you a very different cash flow profile than one doing the same revenue on pure project work.
Client Relationship Depth
Find out who actually talks to clients week to week. If every major client relationship runs through the owner, that means more transition work for you and some client risk you'll want to get comfortable with before closing. Ask to see the org chart, client assignments, and whether any consultants have been with the firm for five or more years. Long-tenured consultants who own client relationships are a great signal that revenue will hold through the transition.
Backlog and Pipeline Visibility
Ask for a list of signed work orders or contracts and a pipeline report showing upcoming project starts. A firm that can show you two quarters of confirmed backlog gives you real confidence in year-one cash flow under new ownership. If the pipeline is more conversational than contractual, that's worth factoring into how you think about risk and pricing.

FAQ
Consulting Services Business Acquisition
What should I look for when buying a consulting business?
Three things tend to matter most: recurring retainer revenue, client relationships spread across the team rather than concentrated with the owner, and consultant tenure. Ask for a breakdown of retainer versus project revenue, a list of clients with their tenure and assigned consultant, and any signed contracts or backlog. Browse consulting businesses for sale on Rejigg to see how these firms are positioned by sellers.
How much does a consulting business cost?
Most consulting businesses sell for 2 to 8 times their annual profit. Owner-operated firms with mostly project work tend to sell in the 2 to 4x range, while firms with a management team and strong recurring retainer revenue can reach 4 to 8x. Run your financing through the SBA loan calculator to see what monthly payments might look like at different price points.
How do I evaluate a consulting business before buying?
Start with the revenue breakdown: ask what percentage is recurring retainer versus one-time project work. Then look at client concentration, consultant tenure, and whether clients have renewal history. Request the last three years of financials and a current client list with revenue by account. The questions worth spending the most time on are who owns each client relationship and how those relationships would hold up through a transition.
What due diligence questions should I ask about a consulting business?
Some good ones to start with: What percentage of revenue is on retainer versus project work? Who manages each major client relationship? Have any clients been informed of the potential sale? What is the average client tenure? Are there signed contracts or statements of work in place for the next 6 months? What would it take for the top three clients to leave? These questions help you understand the real shape of the business before you're too far into the process.
Where can I find consulting businesses for sale?

How do I handle transition risk when buying a consulting firm?
Earn-outs are common in consulting acquisitions for good reason. A typical structure ties 15 to 30% of the purchase price to client retention and revenue targets over the first 12 to 24 months after close. This keeps incentives aligned for both sides. It's also worth planning for a transition period where the seller introduces you to clients and stays involved on key accounts, typically 6 to 12 months.
Does it matter if a consulting firm has proprietary methodologies or tools?
It's worth paying attention to for a couple of reasons. Documented methodologies make it easier to train new consultants and maintain quality after you take over. Proprietary tools or software that clients rely on create switching costs that naturally reduce churn risk. Ask whether the firm's approach is documented in writing, whether clients have been trained on any proprietary tools, and whether those tools are owned by the business or dependent on external vendors.
