Due diligence

What to Look For

Practical guidance from hundreds of real acquisition conversations.

Recurring Service Contracts

  • Ask what percentage of revenue comes from ongoing maintenance agreements and monitoring contracts versus one-time installation projects.
  • Businesses where a meaningful share of income comes from service contracts that renew each year are more predictable from day one.
  • That recurring revenue percentage shapes everything from your risk profile to the financing terms you can get.

Team Credentials and Clearances

  • Security clearances, locksmith licenses, and low-voltage certifications take years and real cost to build.
  • A team where most technicians hold active credentials is a competitive advantage that new entrants simply can't replicate quickly.
  • Ask for a current list of which employees hold which certifications and when each one expires.

Contract Backlog

  • Ask for a full contract list with expiration dates, option periods, and the realistic likelihood of renewal.
  • Government and commercial contracts with option years that extend well past closing give you revenue visibility that most acquisitions don't offer.
  • Contracts where the company is effectively the only qualified vendor in a given area are particularly worth getting excited about.

Full Service Capability

  • Companies that install, monitor, and service cameras, access control, intrusion systems, and alarms under one roof hold their clients more durably than specialists.
  • Clients prefer a single vendor for their physical security needs, and full-service capability is a big part of why they stay.
  • Understand which services the company offers and how revenue is distributed across installation, monitoring, and service.

Management Independence

  • Ask how daily operations are structured: who handles installs, dispatch, and technician oversight when the owner is out.
  • A security company where an operations manager runs the show without the owner's daily involvement is one you can step into and run.
  • The further the owner has stepped back from day-to-day management, the more transferable the business is.

FAQ

Physical Security Services Business Acquisition

What should I look for when buying a physical security services business?

Start with the recurring revenue base. Businesses where a meaningful share of income comes from maintenance agreements and monitoring contracts are more predictable than those relying entirely on installation projects. Then look at the team's credentials. Security clearances, licenses, and certifications take years to build and are a real competitive advantage. Browse physical security services businesses for sale on Rejigg to see what's currently available.

How much does a physical security services business cost?

Most physical security businesses sell for 3 to 8 times annual profit, with the range reflecting recurring revenue share, team credentials, contract backlog, and management independence. Companies with government contracts extending years into the future and credentialed teams tend to command the higher multiples. Use the SBA loan calculator to model your financing options.

How do I evaluate a physical security services business before buying?

Ask for a revenue breakdown separating service contracts and monitoring from installation projects. Get a full contract list with expiration dates and option years. Review the team credentials document to understand which employees hold clearances and licenses. Walk through how day-to-day operations are managed and who handles dispatch and technician assignments when the owner isn't there.

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

Ask what percentage of revenue comes from service agreements versus one-time installs, and how that mix has trended over the past three years. Get the contract list with option years and renewal history. Ask which employees hold security clearances and how the facility clearance is maintained. Understand the locksmith and low-voltage licensing requirements in each state where the company operates. Ask about the transition plan for clearance transfer.

Where can I find physical security services businesses for sale?

Rejigg connects buyers with owners of security integration companies, guard services businesses, monitoring companies, and government-cleared security contractors. You can browse physical security services businesses for sale on Rejigg and connect with owners directly.

How do security clearance transfers work when buying a security business?

Facility clearances require a formal ownership change process through the Defense Counterintelligence and Security Agency, and new owners may need to obtain their own personal clearances, which can take several months. It's critical to start this process early and work with the seller to ensure continuity. Individual employee clearances typically remain active as long as the employees stay with the company, which is why retaining your cleared workforce is a top priority in these transactions.

How much does recurring revenue matter in a security company acquisition?

It matters a lot, both for valuation and for financing. Security companies with 25 percent or more of revenue from maintenance agreements and monitoring contracts consistently attract more buyer interest and better financing terms than those relying entirely on installation projects. Recurring revenue gives lenders confidence in the business's ability to service debt, which often means more favorable SBA loan terms.
