What to know

What to know about buying a security technology & hardware business

How security technology & hardware businesses are valued

Asking prices are set as a multiple of earnings: 3x–8x annual profit, depending on recurring revenue, team depth, and customer mix.

Where you land in that range depends on how much of your revenue comes from ongoing service and monitoring contracts versus one-time installation projects, and whether the business runs without you in the field.

Service and monitoring contracts that renew each year
Trained, certified technicians who stick around
Equipment already installed in customers' buildings
Customers in different industries

What buyers of security technology & hardware businesses look for

Security companies looking to expand into your area or add new services
Companies in related trades like IT services, electrical, or building management who want to add security
First-time buyers with technical backgrounds who like the idea of steady monitoring revenue
Investors building a group of regional security companies

The first questions buyers ask:

Licensing Transfer. Can the buyer legally and practically keep doing the work on day one, and which licenses matter in each jurisdiction?
RMR Durability. What happens to monitoring and service revenue when ownership changes, and what can actually cancel?
Job Margins. Are your install margins repeatable, and can you show gross margin by job type with evidence?

Due diligence

What to Look For

Practical guidance from hundreds of real acquisition conversations.

Recurring Monitoring Revenue

Ask for a breakdown of revenue between project work and recurring contracts, and look at what the renewal rate looks like year over year.
Monthly monitoring and service agreements are the most valuable part of most security businesses because they keep generating income long after the installation job is done.
A business where monitoring revenue covers operating costs even during a slow installation period is in a strong position.

Crew Depth and Certifications

Ask for a list of technicians, their certifications, how long they've been with the company, and what a realistic retention plan looks like post-sale.
Licensed, certified technicians are genuinely hard to find and train — a security company where two or three lead technicians have multi-year tenure and the right certifications is a much more stable acquisition than one where the owner is the only qualified installer.
Find out whether any key certifications are held personally by the owner or tied to the company entity.

Customer Mix Across Verticals

Ask for a revenue breakdown by customer type and look at whether any single account or industry represents more than 20 to 25 percent of total income.
Security companies that serve commercial buildings, schools, apartment complexes, and government facilities are more resilient than those concentrated in a single vertical.
When one sector slows down, others carry the business.

Installed Equipment Base

Ask for a count of active monitored accounts and how long those accounts have been in place.
The physical equipment already installed in customers' buildings is one of the most durable sources of customer retention in this industry — replacing it would be expensive and disruptive, so customers tend to stay for service and monitoring even when budgets are tight.

Licenses and Contract Transferability

Ask whether licenses are held by the company or by the owner personally, and what the process looks like for each.
Security businesses often hold state contractor licenses, alarm dealer registrations, and government or school district contracts that took years to obtain.
Confirming these transfer cleanly before you get deep into diligence avoids major surprises at closing.

Read the Owner's Guide

Security Technology & Hardware Business Acquisition

How do I contact the owner of a business I found on Rejigg?

Create a free Rejigg account; owners, and the brokers who run some sales, only hear from buyers through the platform. Open the listing to see the full profile: city, team size, financials, what is for sale, and the reason for selling. Sign Rejigg's standard Fee & Confidentiality Agreement for that business; it is the same form for every deal. Verify your phone, then send your pitch from the listing. Replies, meetings, and documents all run through Rejigg.

Can I email Rejigg to get introduced to an owner?

No. Rejigg does not forward emails to owners or brokers, so a note to support@ or hello@ with a listing link will not reach them. Create a free account, open the listing, sign the agreement for that business, verify your phone, and send your pitch; that reaches them in a few minutes.

Can the buyer legally and practically keep doing the work on day one, and which licenses matter in each jurisdiction?

Buyers are checking whether crews can keep installing and servicing systems immediately after close. If the qualifying agent is the owner or one key employee, revenue can stall while the buyer gets a replacement approved, even if customers want to stay. That risk often drives longer transitions, holdbacks, or delayed closes.

What happens to monitoring and service revenue when ownership changes, and what can actually cancel?

Buyers want to see whether recurring revenue is backed by assignable contracts and consistent service, not personal relationships and handshake promises. They also look at security-specific churn drivers like false alarms, response times, property manager turnover, and forced platform changes. Strong RMR supports higher multiples, while shaky RMR often pushes the deal toward earnouts.

Are your install margins repeatable, and can you show gross margin by job type with evidence?

Security installs can look profitable until you account for programming, commissioning, rework, and unbilled change orders. Buyers want proof that margin comes from process and job selection, not from a few lucky projects or end-of-quarter vendor rebates. Clear job-type margin ranges reduce retrades when diligence gets into job costing.

How much of your backlog is signed, scheduled, and buildable, and how does it map to crew capacity?

Buyers discount backlog that is verbal, unfunded, stuck in submittals, or impossible to staff with your current tech bench. They care about near-term cash flow and whether backlog converts without overtime, reschedules, and margin bleed. A backlog view tied to skills and calendar capacity signals a controlled operation.

Do your financials stand on their own, with clean books, documented add-backs, and support for RMR, job mix, and working-capital swings?

Buyers and lenders need earnings they can reconcile to projects, service, and RMR billing. They also model working capital, since integrators often pre-buy hardware, carry AR, and deal with pay-when-paid terms. Messy financials and unsupported add-backs commonly lead to retrades, slower financing, or a failed close.

Walk me through a service call from dispatch to invoice, and what does ticket aging look like?

Service performance protects RMR and future upgrade revenue, especially when sites have access-control permissions, camera storage issues, or network changes. Buyers use ticket aging, callback rates, and ticket notes to judge whether the service department is under control. A tight workflow also reduces owner dependency and improves retention after close.
