1. What every private security company invoice must include

A compliant private security company invoice has eight parts: your business name and contact info, a unique invoice number, issue date, payment due date, the customer's name and address, an itemized list of work, the total amount due, and accepted payment methods. If you're collecting sales tax, that line is required too.

2. Set your line items

Most private security companys structure invoices around these 4 categories:

Unarmed officer — per hour — billed by hour at a ~$35 default.
Armed officer — per hour — billed by hour at a ~$65 default.
Vehicle patrol — billed by flat.
Holiday surcharge — billed by pct.

3. Set payment terms

The standard for private security companys is Net 30 — payment due within 30 days of the invoice date.0 Spell out late-fee terms (most states cap monthly late fees around 1.5%) and accepted payment methods on the invoice itself.

4. Licensing & legal disclosures

State security agency license required. Each officer must hold state guard card; armed officers need separate firearms permit.

5. Send and follow up

Send the invoice the same day work is completed (or upon milestone for larger projects). Use software that tracks opens and lets the customer pay by card or bank transfer in one click — the average private security company-class invoice gets paid 2× faster when the customer can pay online without leaving their inbox.
