Invoice Payment Reminder Sequence

Write a payment reminder sequence for an unpaid invoice. Firm, specific, and not embarrassed. INVOICE Number and amount: [N, AMOUNT] Due date: [DATE] What it was for: [PROJECT] Client contact: [NAME] Late fee in the contract: [YES — TERMS | NO] How they pay: [LINK OR INSTRUCTIONS] Today's date relative to due: [BEFORE | ON | 7 LATE | 21 LATE | 45 LATE] WRITE FIVE NOTES, AND TELL ME WHICH ONE TO SEND TODAY 1) Three days before due, a short courtesy with the link. 2) Due date, two lines. 3) Seven days late. Restate the amount, the original due date, and the late fee if one exists. Ask if the invoice is stuck with someone else. 4) Twenty-one days. Name the next step I will take on a specific date (pause work, or send to [PERSON]). Only include steps I said I will actually do. 5) Forty-five days. Final, short, no new warmth, no threats I did not authorize. If I did not authorize collections or a lawyer, do not mention them. Subject lines that include the invoice number. No jokes about being "just a friendly bump" four times.
