How to invoice security work

Bill by the hour for ongoing coverage, per event for one-off jobs, or a flat monthly rate for contracts. List each post, shift, or event with hours and rate, and note the site and dates covered. For contracts, reference the agreement and billing period. Separate any overtime, holiday, or armed-guard premiums onto their own lines so the client sees exactly what drives the total.

Billing contracts and getting paid on time

Commercial security is usually billed monthly against a contract, and property managers pay on set terms like Net 30. Invoice on a consistent schedule at the start of each period, keep sequential invoice numbers, and offer online payment — invoices with convenient online payment get paid up to twice as fast, per Xero (2024) — to keep cash flow steady.

How to make a security services invoice in 7 steps

  1. Open the invoice with the fields already set up

    Start from this page so the invoice loads with line items and wording used for security services work. Creating and previewing needs no account.

  2. Add your details and the client

    Enter your business name, address and contact details, then the client name and billing address exactly as they should appear on the record.

  3. Give the invoice a number and dates

    Use a unique invoice number in one unbroken run, then set the issue date and the due date so the payment term is unambiguous.

  4. Replace the sample lines with the work you did

    Swap the example lines for the real job. Describe the unit you are billing, whether that is hours, visits, or units, and put the rate on the same line. The starting lines here open with security guard (per hour).

  5. Check the totals and any tax

    Totals calculate as you type. Confirm the quantities, rates and any tax line against your own records, since sales tax rules and what is taxable differ by jurisdiction.

  6. State how and when to pay

    Add the payment terms, the methods you accept and any late fee your agreement allows, so the client has no reason to wait for clarification.

  7. Preview, then download the PDF

    Read the finished invoice before you send it. Preview is free; a PDF download costs $4.99, or is included with Unlimited.

Frequently asked questions

How do I invoice a monthly security contract?

Add a line for the monthly contract amount (e.g. "Security coverage — March, 160 hours") and note the post and hours included. Add separate lines for any extra shifts or overtime, then download the PDF. Repeat each month with a new invoice number.

How should security companies bill overtime or holiday rates?

Put premium hours on their own line at the higher rate (e.g. "Holiday coverage — per hour") so the standard and premium rates are clear. This keeps the invoice transparent and easy for the client to approve.
