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.

FAQ

Professional Services Businesses in California

What should I look for when buying a professional services business?

Four things tend to matter most: how much revenue is recurring versus one-time, who actually owns each client relationship, whether licensed or credentialed professionals beyond the founder will stay, and how spread out the client base is. Ask for a revenue breakdown by type, a list of clients with their tenure and assigned team member, and any signed contracts. Browse professional services businesses for sale on Rejigg to see how these firms present themselves to buyers.

How much does a professional services business cost?

Most professional services businesses sell for 2 to 9 times their annual profit depending on the category, revenue predictability, and team depth. Owner-operated firms where most work runs through the founder tend to sell in the 2 to 4x range. Firms with a management team, strong recurring revenue, and licensed staff can reach 6 to 9x. Use the SBA loan calculator to model monthly payments at different price points.

How do I evaluate a professional services business before buying?

Start by asking what percentage of revenue renews automatically versus has to be re-won. Then look at who manages each major client relationship, the credentials and tenure of key staff, and how dependent the business is on the founder's personal relationships. Request the last three years of financials and a client list with revenue by account and assigned team member. The question worth spending the most time on is how well revenue would hold through a transition.

What due diligence questions should I ask about a professional services business?

Good questions to start with: What percentage of revenue is on retainer or recurring contract versus project work? Who manages each major client relationship? Which staff hold professional licenses or credentials, and are those tied to individuals or the company? What is the average client tenure? Have any clients renewed within the past 12 months without being asked? These questions help you understand whether you're buying a real business or a job that runs through one person.

Where can I find professional services businesses for sale?

Rejigg is built specifically for buying and selling professional services businesses, including consulting, accounting, engineering, legal services, and HR firms. You can browse professional services businesses for sale on Rejigg, message sellers directly, and review financials in a secure deal room.

How do professional licenses and credentials affect the acquisition process?

In fields like auditing, engineering, and land management, professional licenses are tied to individuals, not the company. If the founder is the only licensed professional, the buyer needs a plan for keeping that capability in place after the sale. The best situations are firms with multiple licensed staff members beyond the owner. Ask early who holds which licenses, which ones are required to operate, and whether those team members plan to stay.

How do I handle transition risk when buying a professional services firm?

Earn-outs are common in professional services for good reason. A structure tying 15 to 30 percent of the purchase price to client retention and revenue targets over the first 12 to 24 months keeps incentives aligned for both sides. It's also worth negotiating a transition period where the seller introduces you to key clients and stays involved on major accounts, typically 6 to 12 months. The goal is to give clients enough time to build trust with you before the prior owner fully steps away.
