What every private investigator invoice must include

A private investigator invoice is more than a request for payment — it's a legal record. To stay compliant and get paid on time, make sure your invoice has these elements:

  • Your full business name, address, and contact info
  • A unique invoice number (e.g. PRIV-001) for tracking
  • Your client's name, business name and address
  • Issue date and due date (Net 14 or Net 30 is standard)
  • Itemized list of services with quantities and rates
  • Subtotal, tax (if applicable) and total amount due
  • Payment methods accepted (bank transfer, card, PayPal)
  • Late fee terms if you charge them (1.5% per month is standard)
  • Your tax ID — EIN for businesses, SSN for sole proprietors

Frequently asked questions

When should I send a private investigator invoice?+

Send your invoice immediately after delivering work or completing a milestone. Most private investigators use Net 14 or Net 30 payment terms.

What hourly rate should a private investigator charge?+

Typical private investigator rates range from $75/hr to $250/hr depending on experience, geography and project complexity. Mid-career private investigators average around $163/hr.

Does a private investigator invoice need a tax ID?+

If you operate as a sole proprietor in the US, you can use your SSN. Most private investigators apply for a free EIN from the IRS to keep their SSN off invoices.

Can I charge a late fee?+

Yes — most states allow 1.5% per month (~18% annualized) on unpaid invoices. Always state the late fee in writing on the invoice itself.

Is this invoice template legally binding?+

An invoice itself isn't a contract, but it's a legally enforceable record of services rendered and amount owed. Pair it with a signed contract (free via our eSign tool) for maximum protection.
