Security Guard Invoice Template: Hourly Rates and Overtime
Set up a security guard invoice template that bills guard hours by post, holiday and overtime premiums, patrols and supervisors clearly, with a worked sample.
Quick answer: A security guard invoice template should bill hours by site, post and guard classification at the contracted rate, with overtime and holiday hours on separate lines showing the premium. Add patrols, alarm call-outs and supervisor hours as their own items, reference the contract or PO number, state the billing period, and attach the matching timesheets.
Security billing is mostly arithmetic, but it is arithmetic across many shifts, guards and sites. A client's accounts payable team receives an invoice for hundreds of hours and has to decide whether it is right. If the hours do not match their sign-in sheets, or overtime appears without explanation, the whole invoice waits. A clear security guard invoice template breaks the total into posts, classifications and premium hours so it can be checked quickly and paid on time.
This guide explains common billing structures for guard services, what each invoice should contain, how to handle overtime and holidays, how to bill patrols and call-outs, and a worked sample with the arithmetic. It applies to small guard companies, event security firms and independent officers who contract directly with clients.
How security services are billed
Most security contracts set an hourly bill rate per guard classification, with premiums for certain hours. The table below lists the usual structures. All figures in this guide are illustrative; bill rates depend on location, wage levels, licensing, insurance and contract terms.
| Billing model | How it works | Typical use | Invoice line example |
|---|---|---|---|
| Hourly by classification | Hours x rate for unarmed, armed, supervisor, K9 | Static posts, ongoing contracts | Unarmed officer, Post 1 Lobby, 168 hrs x $28 |
| Overtime premium | Contracted multiplier on hours the client requested beyond schedule | Extra coverage, short-notice shifts | OT, client request 12 Mar, 6 hrs x $42 |
| Holiday premium | Multiplier on named holidays | 24/7 posts | Holiday hours, 25 Dec, 24 hrs x $42 |
| Mobile patrol | Per visit or per scan, sometimes a monthly minimum | Lots, construction sites, closed buildings | Patrol visits, 14 x $30 |
| Alarm response | Per call-out, sometimes plus time on site | After-hours alarms | Alarm response, 18 Mar 2:14 am |
| Event package | Flat fee or hours with a minimum per guard | Concerts, weddings, sports | Event security, 6 guards x 5 hrs min |
| Fixed monthly | Set fee for a defined schedule | Stable long-term contracts | Monthly coverage per schedule A |
Pay rate vs bill rate
Your bill rate must cover far more than the guard's wage: payroll taxes, workers' compensation, liability insurance, licensing, training, uniforms, supervision, scheduling, overhead and profit. Clients only see the bill rate, but your costing should track both. When the law requires you to pay guards overtime, for example under the US Fair Labor Standards Act overtime rules for non-exempt employees, that cost is yours unless the contract lets you pass a premium to the client. That is why the overtime clause in your service agreement matters so much.
What to include in a security guard invoice template
Use this checklist for every invoice:
- Company name, address, contact details and your security company license number where required.
- A unique invoice number and invoice date. Our invoice number generator can suggest a pattern such as SEC-2026-0412.
- The client's legal name, billing address, site address and contract or PO number. See our guide to PO numbers on invoices.
- The billing period, such as 1 to 15 March 2026.
- Hours by site and post, split by classification: unarmed, armed, supervisor, K9.
- Overtime hours on their own lines with dates, the reason and the multiplier.
- Holiday hours on their own lines with the holiday date.
- Patrol visits, alarm call-outs and any equipment such as vehicles, radios or barriers.
- Tax where applicable, the total, payment terms, due date and payment details.
- A note referencing attached timesheets or scheduling reports.
Guards' names or ID numbers can go on an attached report rather than the invoice itself, which keeps the invoice readable and limits how widely personal details travel.
Overtime and holiday billing
Overtime is the line clients question most on any security guard invoice template. Avoid disputes by agreeing in the contract on three points: which hours can be billed at a premium, what the multiplier is, and who can authorize extra hours. A common pattern is that client-requested extra coverage, short-notice shifts and hours beyond the agreed weekly schedule are billable at a premium, while overtime caused by your own staffing gaps is not.
On the invoice, never blend premium hours into the regular line. Show them separately with the date, the reason and the request reference:
- "Overtime, extra officer requested by J. Ortiz on 12 Mar, 6 hrs x $42.00."
- "Holiday rate, 25 Dec, Post 1, 24 hrs x $42.00."
Holiday billing should follow a list of named holidays in the contract rather than a general phrase like "public holidays". Lists differ by country, state and employer, and some government contracts set their own holiday rules. If your security services invoice includes a holiday the client does not recognize, it will come back to you.
Timesheets and proof of hours
Attach timesheets, scheduling reports or guard tour records to every invoice. Clients often compare your hours with their own sign-in logs or access control data, so make sure the totals match before you send. Our timesheet template guide shows a layout that totals easily into invoice lines, and our guide on how to invoice for hourly work covers rounding, minimums and approvals.
Patrols, call-outs and extras
Not all security work is static guarding. Mobile patrols, alarm response and event work each need their own line types:
- Mobile patrols: bill per visit or per checkpoint scan, with the count for the period. Keep patrol logs with timestamps.
- Alarm response: bill per call-out with the date and time, plus time on site beyond a set period if the contract allows.
- Event security: bill per guard with a minimum number of hours, and list supervisors and crowd managers separately.
- Equipment and vehicles: patrol vehicles, radios, metal detectors or barriers rented to the client.
- Reports and investigations: incident reports beyond the standard scope, or time spent with police and insurers, if billable.
Sample security guard invoice
Below is an illustrative invoice for a two-week period at an office building with a 24/7 lobby post, a holiday, a supervisor and night patrols. All rates are examples, and no tax is charged in this example.
| Description | Qty | Rate | Amount |
|---|---|---|---|
| Unarmed officer, Post 1 Lobby, regular hours, 18 to 31 Dec | 312 | $28.00 | $8,736.00 |
| Holiday rate (1.5x), Post 1, 25 Dec | 24 | $42.00 | $1,008.00 |
| Overtime (1.5x), extra officer requested by client, 29 Dec | 6 | $42.00 | $252.00 |
| Site supervisor visits, hours | 10 | $35.00 | $350.00 |
| Mobile patrol, parking structure, visits | 14 | $30.00 | $420.00 |
| Total due | $10,766.00 | ||
The arithmetic:
- Post hours in 14 days: 14 x 24 = 336 hours, of which 24 are holiday hours, leaving 336 - 24 = 312 regular hours.
- Regular: 312 x $28.00 = $8,736.00.
- Holiday and overtime rate: $28.00 x 1.5 = $42.00.
- Holiday: 24 x $42.00 = $1,008.00. Overtime: 6 x $42.00 = $252.00.
- Supervisor: 10 x $35.00 = $350.00. Patrols: 14 x $30.00 = $420.00.
- Total: $8,736.00 + $1,008.00 + $252.00 + $350.00 + $420.00 = $10,766.00.

A sober layout such as the slate invoice template suits corporate and facilities clients. The generator applies one tax rate to the whole invoice and does not track hours, schedule guards or send invoices, so total hours from your timesheets first and email the PDF with the reports attached.
Payment terms and large clients
Security companies carry a heavy payroll: guards are paid weekly or biweekly, while clients may pay 30, 45 or 60 days after invoice. That gap can strain cash flow quickly. Negotiate terms that fit your payroll, invoice on a cycle that matches it, and read our guide to net 60 and net 90 payment terms before accepting long terms from a large client. When a client questions hours, respond with the timesheets and approvals right away; our guide to handling an invoice dispute covers how to keep the undisputed part moving.
Guard classification also matters for your own compliance. Guards working set shifts under your supervision are usually employees rather than contractors in many jurisdictions; see our comparison of W-2 vs 1099 workers for the US view. Licensing requirements differ by state and country; the US Bureau of Labor Statistics overview of security guard occupations notes that most states require guards to be registered or licensed, and the UK, India, Pakistan and others have their own licensing regimes.
Common mistakes on a security guard invoice template
- One blended rate. Mixing armed, unarmed and supervisor hours under one rate breaks most contracts and cannot be audited.
- Unexplained overtime. Premium hours without a date, reason and approval are the first lines accounts payable will reject.
- Holiday dates the contract does not list. Bill premiums only for named holidays.
- Hours that do not match the client's logs. Reconcile before sending, not after a dispute.
- No PO or contract number. Large clients route invoices by PO; without it, payment stalls.
- Billing your scheduling gaps as client overtime. If you caused the overtime, it is usually your cost.
- Missing billing period. Overlapping or unclear periods lead to double billing claims.
Building your security invoicing routine
A reliable security guard invoice template has the contract details, classifications and rates pre-filled, with lines for regular, overtime and holiday hours ready to update each period. Close timesheets on a fixed day, reconcile them with the client's records where you can, and invoice within a day or two. The faster and cleaner the invoice, the shorter the gap between paying guards and getting paid. For more trade-specific layouts, browse our industry invoice guides.
Frequently asked questions
What should a security guard invoice include?
Include your company name, license number where your jurisdiction requires one, a unique invoice number, the invoice date and billing period, and the client's name, site address and PO or contract number. List hours by post and guard classification, such as unarmed, armed or supervisor, with the contracted rate. Show overtime and holiday hours on separate lines, then patrols, call-outs, equipment, tax, payment terms and the due date.
How do security companies bill overtime to clients?
Billable overtime is set by the service contract, not by payroll law. Many contracts bill client-requested extra hours, short-notice shifts and hours beyond the agreed schedule at a premium, often 1.5 times the standard rate, while overtime caused by the security company's own scheduling is absorbed. Show overtime hours on their own dated line with the multiplier, and attach the approval or request that triggered them.
What is the difference between pay rate and bill rate for security guards?
The pay rate is what the guard earns per hour. The bill rate is what the client pays per hour and must cover wages, payroll taxes, insurance, training, uniforms, supervision, overhead and profit. Clients see only the bill rate on the invoice. Keep the two separate in your own costing so that overtime premiums you pay guards are matched by premiums in the contract.
Which holidays are billed at a premium for security services?
Only the holidays listed in your contract. A common approach is to name each holiday, such as New Year's Day, Independence Day, Thanksgiving and Christmas Day in the United States, and set a holiday bill rate, often 1.5 times standard. Bill holiday hours on separate lines with the date. Some public-sector contracts have their own holiday rules, so read the solicitation carefully before you price.
Do security guards need a license to invoice clients?
Licensing rules vary widely. In the United States many states license security companies and individual guards, with stricter rules for armed guards, while others have little regulation. In the UK, front-line guards need a Security Industry Authority licence. Other countries set their own rules. Put your company license number on invoices where it is required or expected, and check the rules for every jurisdiction where you place guards.
How do I bill mobile patrols on a security invoice?
Mobile patrols are usually billed per visit or per patrol hit, sometimes with a monthly minimum, rather than by the hour. List the number of visits in the billing period times the per-visit rate, and keep patrol logs or scan records showing each visit's date and time. Alarm response call-outs are normally a separate line with their own rate, because they are unscheduled.
How often should a security company invoice clients?
Weekly, biweekly or monthly invoicing are all common, often matched to the payroll cycle so cash comes in close to when wages go out. Monthly works for stable contracts with large clients, while weekly suits event security and short contracts. Whatever the cycle, state the billing period on each invoice and make sure it lines up with the timesheets or scheduling records you attach.
Can I use a free invoice generator for security services billing?
Yes, for small companies and event security. Enter each post and classification as a line with hours and rate, add overtime and holiday hours as their own lines, apply one tax rate if needed and download a PDF. The generator does not track guard hours, schedule shifts or send invoices automatically, so total hours from your timesheets or scheduling app first and attach those records.
