1. North Dakota-specific invoice requirements
- Sales tax line: 5.00% state rate. Most services rendered in North Dakota are exempt from sales tax — but materials, parts, and tangible goods are not. State 5%; combined typically 6-8.5%.
- Late-fee cap: North Dakota statute N.D. Cent. Code §47-14-05 caps interest on unpaid invoices at 1.5% per month. Spell out the rate in writing on every invoice and in your contract — courts won't enforce undisclosed fees.
- Right-to-cancel notice: Customers in North Dakota get 72-hour cancellation rights on certain home-services contracts. Disclose this in your terms.
2. Private Security Company line items + standard terms
Every private security company invoice in North Dakota should itemize work clearly. Standard private security companys use Net 30 terms with no deposit required.
- Unarmed officer — per hour — billed by hour (~$35 default).
- Armed officer — per hour — billed by hour (~$65 default).
- Vehicle patrol — billed by flat.
- Holiday surcharge — billed by pct.
3. Private Security Company licensing in North Dakota
State security agency license required. Each officer must hold state guard card; armed officers need separate firearms permit.
4. Send and follow up
Send the invoice the same day work completes. Use software that records open events and offers a one-click online payment so you don't need to chase a check by mail. North Dakota customers expect digital payment options today — accepting card and ACH typically reduces days-to-paid by 30–50%.
