What this letter is
An invoice letter asks a customer to pay for work done or goods supplied, and records what the charge is for. Most invoicing happens by email, but a mailed invoice reaches an accounts-payable department that files paper, gets past a spam filter that silently drops attachments, and gives you a dated record of exactly what you billed and when. It is also the usual next step when emailed invoices have gone unanswered.
What to put in it
- An invoice number, and the date you issued it.
- Who the invoice is from, including the address payment should be sent to.
- What is being charged for — each item or visit, its date, and its amount.
- The total due, and any tax shown separately.
- The payment terms and the date payment is due.
- How to pay, and a reference to quote when paying.
An emailed invoice can be filtered, forwarded and forgotten, and you have no record that it arrived. A mailed invoice lands in the accounts-payable process most businesses still run on paper, and leaves you holding a dated copy of precisely what you billed. Certified Mail adds USPS tracking and a delivery record, which matters when an unpaid invoice is heading toward a formal demand.

Good to know.
Can I attach a detailed breakdown or timesheet?
Yes — attach the pages and they are printed and mailed behind the letter. Pages after the first are $0.49 each.
Should I send an invoice by Certified Mail?
For a routine invoice, First-Class is normally enough. Certified Mail is worth the extra when an invoice is already overdue and you may need to show the client received it.
Does PostalGenie handle the payment itself?
No. PostalGenie drafts and mails the invoice; the client pays you directly by whatever method your letter asks for.

- Genie is an automated AI system, not a person. It drafts each letter from the information you provide and does not add facts or claims you did not supply. AI-generated output may vary or contain errors; you are responsible for reviewing and approving the final letter, and no letter is mailed without your approval.
- Address lookup and verification rely on third-party data and are provided on a best-efforts basis. Accuracy is not guaranteed; you are responsible for confirming the recipient’s address before sending.
- Delivery times are estimates, not guarantees. Statutory deadlines, notice periods and filing requirements vary by state, contract and program — check the ones that apply to you.
