Buying a Security Guard Business

First, the Qualifying Agent

Security guarding is a licensed trade, and the license decides the deal before price does. States license the company itself, often as a private patrol operator, and the license rests on a qualifying agent: a named individual with the state's required experience who backs the company's authority to contract guards. If the selling owner is that person, a buyer needs a qualified replacement in place at close or the company legally cannot operate. Guards are registered separately on top of it, and in California registration carries 32 hours of training inside the first six months. Confirm the qualifier and the guard cards first: neither is a formality and neither survives a change of ownership by itself.

Why Searchers Look at Guard Companies

The draw is contracted, recurring revenue: guard companies bill clients monthly under standing post orders, and demand is non-discretionary and growing, pushed by public-safety concerns and thin police staffing. The market is deeply fragmented under a few global strategics, Allied Universal, GardaWorld, and Securitas, so a searcher buys a local or regional book below their attention and can exit to them later. The honest caveat leads into the next section: this is a labor-arbitrage business with thin margins, so the recurring revenue is real but the profit is a spread that must be defended, not a cushion.

What Guard Companies Trade For

Guard companies trade low because margins are thin. The publisher's security class opens with armed and unarmed guards before camera installation and monitoring. The publisher puts half the market between 1.95x and 3.29x SDE across 2021 to 2025, with a 2.61x median, a $750,000 median sale price and revenue at 0.49x to 1.14x. Advisors quote higher EV/EBITDA figures for platforms, but no publisher of sold data prints an EBITDA multiple for this trade, so read those as the exit rather than the entry. Where a business lands inside the sold band is the spread, contract stickiness, and management depth the next section covers; a book of low-margin contracts with the owner scheduling every shift is worth less than its revenue suggests.

The Bill-Pay Spread and Contract Risk

Two numbers and one risk decide a guard company. The first number is the bill-pay spread: the gap between what clients are billed per hour and the fully loaded cost of the guard, wages, payroll taxes, overtime, workers' compensation, and supervision. That spread is often single digits, so a small wage increase or a client that will not accept a bill-rate pass-through erases the margin. The second is contract concentration: a book leaning on one or two clients can lose most of its revenue on a non-renewal. The risk is turnover: guard attrition runs high, and constant rehiring and retraining is a real cost and a service-quality threat. Read the spread by contract, the client concentration, and the turnover before crediting the margin.

What to Verify in Diligence

The record to assemble before the offer holds:

  • The qualifying agent, the company license, and whether the qualifier stays
  • Guard cards current for every guard, and W-2 rather than contractor status
  • Bill rate versus fully loaded pay by contract, and the real spread
  • Client concentration, contract terms, renewals, and cancellation notice
  • Guard turnover, overtime reliance, and open post coverage
  • Workers' compensation history, experience modifier, and open claims
  • Surety bond, general-liability limits, and any litigation

Financeability Notes

Guard companies finance under SBA 7(a), and lenders read contracted, recurring billing favorably, but they underwrite the thin margin and labor risk closely. Expect the lender to want the qualifying-agent transfer resolved, since a company that loses its license cannot bill, and to weigh client concentration and the workers' compensation record. Model debt service on margin that survives a wage increase, and net of a market salary for a scheduler or operations manager if the seller runs the posts, and stress the biggest client rolling off. The margin risk to underwrite is a wage or minimum-wage increase the company cannot pass through to clients, so read the bill-pay spread and the contract escalators, not just the trailing profit.

Terms in This Industry

What the Data Says

  • BizBuySell's security company benchmarks blend guarding with alarm installation and monitoring. They put sold earnings multiples at 1.95x lower quartile, 2.61x median, 2.73x average and 3.29x upper quartile, on a $750,000 median sale price and 0.85x revenue, at 186 median days on market. Contract-guarding books trade inside that blend, and payroll discipline is what the multiple is really pricing.

  • Security services M&A regained momentum in 2025 after several flat years, with a fragmented market consolidating under global strategics such as Allied Universal, GardaWorld, and Securitas. The advisor's EV/EBITDA figures describe that strategic end of the market, a basis no publisher of sold small-business transactions prints for this trade at all.

  • California licenses the operating COMPANY, not only its guards: no one may engage in the business of a private patrol operator without a license, which runs through a named manager who sits a state exam, and every guard is registered separately. A buyer inherits a license that depends on a person, so the qualifier and the guard cards both have to be in order at close.

What It Costs to Replace the Owner

The multiples above are quoted on SDE, which adds the owner's pay back into earnings, so they hold only if you do the owner's job. Hire someone instead and the going rate for the role comes back out. For this trade that is usually the supervisor over guards and posts, paid a median of $55,940 a year nationally. Subtract it from SDE before applying any multiple, because at a 3x multiple that wage also takes about $167,820 off what the business is worth to you.
