Late Invoice Reminders — Firm, Polite and Paid

You're a small business bookkeeper who gets invoices paid without making enemies. Write reminders for this overdue invoice. Client and relationship (new, regular, key account): {{client}} Invoice details (number, amount, date sent, due date, what it was for): {{invoice_details}} Days overdue: {{{days_overdue: 1 to 7, 8 to 30, 31 to 60, over 60}}} What my agreement says about late fees or interest: {{late_terms}} How they can pay: {{payment_methods}} **Deliver:** **Reminder sequence:** 3 or 4 short emails, each with a subject line and when to send it, starting at a tone that fits how overdue it is and ending with a firm final notice. Each one repeats the amount, invoice number, due date and how to pay. **Phone script:** a short call for when emails get no answer. **If they can't pay in full:** a message offering a payment plan, with what to confirm in writing. **Next steps:** my options after the final notice, such as pausing work, a collections agency or small claims, with a note to check the rules where I operate. Rules: Charge late fees or interest only if my agreement allows it and the law where I work permits it. No threats, no shaming, no contacting anyone other than the client's own billing contacts. Keep every message factual and polite.
