A security services invoice bills guard hours by post and shift, listing each assignment with dates, hours, and the contracted hourly rate. Typical U.S. billing rates run $25–$50 per hour for unarmed guards and $35–$75 for armed guards — roughly 1.5–1.8× the guard's wage to cover insurance, licensing, and supervision. Invoices should carry the company's security license number and bill weekly or monthly against the service agreement.

Security Invoice Template

Security billing is schedule math: posts, shifts, and hours that have to reconcile against the client's own sign-in logs. This template structures the invoice the way contracts are audited — one line per post and period with hours and the contracted rate, holiday and overtime differentials shown separately, and your license details printed where procurement expects them.

What to include on a security invoice

01

Post and site identification

"Main gate — Riverside Distribution Center" per line. Multi-site contracts are reconciled post by post; one blended line can't be audited.

02

Service period and hours per line

Date range, scheduled hours, and actual hours billed. Where your logs and the client's sign-in sheets disagree, the line-level detail is what gets you paid for the hours that match.

03

Rate by guard classification

Unarmed, armed, supervisor, K9 — each classification at its contracted rate. Mixing classifications under one rate violates most service agreements.

04

Overtime and holiday differentials

Billed at the contracted multiplier (commonly 1.5×) on separate lines with the triggering dates named. Unexplained premium hours are the first thing AP flags.

05

Your security license number

State private-security license (PPO/B-license or equivalent) printed on the invoice. Many corporate and government clients can't process payment to an unlicensed-looking vendor.

06

Reference to the service agreement

Contract or PO number. Security is recurring contract work — every invoice should declare which agreement and rate schedule it bills under.

07

Incident or special-coverage charges

Emergency call-outs, event coverage, or extra posts added mid-period get their own clearly labeled lines with authorization references (who requested, when).

Unarmed guard (standing post)$25 – $50/hourRegion and site risk drive the spread
Armed guard$35 – $75/hourInsurance and licensing premium

Billed rates run roughly 1.5–1.8× guard wages to cover liability insurance, training, licensing, scheduling, and supervision. Government contracts may be subject to prevailing-wage requirements that set floors.

How security billing actually works

Recurring contract coverage: the weekly/monthly cycle

Standing contracts bill on a fixed cycle — weekly for staffing-heavy sites, monthly for smaller ones — with one line per post per period. Attach or reference the shift detail report; AP departments that can tie invoice lines to sign-in logs pay without queries, and queries are where security invoices go to die for 45 days.

Event security: quote, minimums, same-week billing

Events bill per guard-hour with a 4-hour minimum per guard, quoted up front and invoiced immediately after the event while headcounts are fresh. New event clients should prepay or pay a deposit — one-off events have no relationship to protect a Net 30 promise.

Mid-contract additions and emergency coverage

Extra posts, strike coverage, or emergency call-outs get invoiced on the next cycle as separate labeled lines with the authorizing contact and date ('additional post per J. Alvarez email, June 3–10'). Unauthorized-looking additions are the most disputed line type in security billing — the authorization reference is the fix.

Invoicing mistakes that cost security professionals money

Hours that don't reconcile to the site logs

If the client's sign-in sheet shows 158 hours and your invoice shows 164 with no detail, the whole invoice waits while six hours get argued. Bill from your verified shift reports, line by post, and flag known variances proactively on the invoice.

Blending overtime into the base rate

Quietly averaging holiday premiums across regular hours makes your base rate look inflated and breaches rate-schedule contracts. Differentials go on their own lines at the contracted multiplier.

Missing license and insurance references

Corporate procurement and government clients validate vendor compliance at payment time. License number on the invoice and current COI on file prevent the 'pending vendor compliance review' hold.

Letting receivables age on a labor business

You pay guards weekly; a client on day 50 of Net 30 is financing their security with your payroll. Enforce the day-20 reminder, charge contracted late fees, and treat two late cycles as a re-negotiation trigger — security margins can't absorb 60-day money.

FAQs

How much do security companies charge per hour?

Typical U.S. billed rates are $25–$50 per hour for unarmed guards and $35–$75 for armed guards, with supervisors and specialized coverage higher. The billed rate is usually 1.5–1.8× the guard's wage, covering liability insurance, licensing, training, and supervision.

What should a security services invoice include?

Your company details with state license number, the client's PO and contract reference, one line per post per period showing site, dates, hours, guard classification, and rate, separate lines for overtime and holiday differentials, any authorized additional coverage, and the payment terms from the service agreement.

How often do security companies invoice?

Weekly or bi-weekly for large staffed contracts (matching payroll exposure) and monthly for smaller sites, on Net 15–30 terms. Event work is invoiced immediately after the event, and new event clients typically prepay.

How is security overtime billed to clients?

At the multiplier in the service agreement — commonly 1.5× the contract rate for over-40-hour weeks and recognized holidays — on separate invoice lines naming the dates. The client pays contracted differentials, not your internal payroll obligations, so the agreement's rate schedule is what governs.

Why does the guard company's license number belong on the invoice?

Private security is a licensed industry in nearly every state, and many clients — especially government and corporate procurement — verify vendor licensing before releasing payment. Printing the license number (and keeping a current certificate of insurance on file) removes a standard payment hold.

Should event security be paid in advance?

For one-off and first-time event clients, yes — full prepayment or a 50% deposit with the balance due before the event. Recurring corporate event clients can move to invoice terms once they have payment history.
