Security System Contractor
Overhead Rate.

Security system subcontractors carry overhead driven by certification requirements, programming and commissioning expertise, and the recurring revenue model that many security contractors pursue alongside project work.

Overhead Benchmarks — Security System Contractors — By Revenue Band

What Normal Looks Like
At Your Revenue Level.

These benchmarks are drawn from SPM's work with commercial security system contractors and industry data. Calculate your actual overhead rate — total G&A expenses divided by total revenue for the trailing 12 months — and compare to your revenue band below.

How to use this data: If you're above the top of the range, specific categories need review. If you're below the bottom, you may be underinvesting in systems and staff. Use the benchmark as a target range, not a single number.

Trade note for Security System Contractors: Security contractors with recurring monthly revenue (RMR) from monitoring and service contracts carry different overhead profiles than pure installation contractors. RMR operations require customer service infrastructure, monitoring center relationships, and service response overhead that changes the overhead rate benchmark. The benchmarks above apply to installation-focused operations.

Why Overhead Rate Gets Off Track

Three Reasons Your
Overhead Is Drifting.

01

Manufacturer Certification Costs Are Scattered

Maintaining certifications across multiple manufacturer platforms — Lenel, Genetec, Milestone, Axis — involves training costs, certification fees, and continuing education that's often scattered across multiple budget lines rather than tracked as a consolidated overhead category.

02

Programming and Commissioning Gets Coded Wrong

System database setup, programming, and commissioning for specific projects are direct job costs — not overhead. When this technical labor gets coded to overhead, installation jobs look less profitable and overhead is artificially high.

03

Service Infrastructure Overhead Bleeds Into Installation

Security contractors who operate both installation and service divisions often have service infrastructure overhead — dispatch, parts inventory, vehicle maintenance — that bleeds into the installation division's overhead rate without clear separation.

How SPM Manages It

Overhead Rate as a
Managed Number.

Certification Cost Consolidation

SPM tracks all manufacturer certification and training costs as a consolidated overhead category in ControlQore — giving a clear picture of the true cost of maintaining multi-manufacturer capability and supporting pricing decisions about which manufacturer platforms to prioritize.

Programming and Commissioning to Jobs

System programming, database setup, and commissioning labor for specific projects is coded to those jobs in ControlQore — not to overhead. Technical labor that directly supports a specific installation belongs in that job's direct cost.

Division-Level Overhead Separation

For security contractors with installation and service divisions, SPM builds separate overhead rate tracking for each division — preventing service infrastructure overhead from distorting installation division overhead rates.

Common Questions

Straight Answers.

How do I calculate my overhead rate?
Add up every expense that isn't a direct job cost for the trailing 12 months — office staff, rent, insurance, equipment payments not allocated to jobs, vehicles, software, marketing. Divide by total revenue for the same period. That percentage is your overhead rate. Compare it to the benchmark for your revenue band above.
Does SPM serve security system contractors at all revenue levels?
SPM's direct engagement covers $1M–$12M in revenue. The benchmark data on this page covers the full revenue spectrum for reference. For contractors above $12M, SPM can make the right introduction to firms that specialize at larger scale.
