Overdue Invoice Payment Reminder Email Sequence

Write a 3-email payment reminder sequence for [BUSINESS_NAME], a [BUSINESS_TYPE], to send to [CUSTOMER_NAME] about an overdue invoice. Invoice details: - Business name: [BUSINESS_NAME] - Business type: [BUSINESS_TYPE] - Customer name: [CUSTOMER_NAME] - Invoice number: [INVOICE_NUMBER] - Amount due: [AMOUNT_DUE] - Days overdue today: [DAYS_OVERDUE] - What they were billed for: [SERVICE_OR_PRODUCT] - Payment link: [PAYMENT_LINK] - Late fee policy (optional — if this is blank or "none", do not invent a fee or mention one): [LATE_FEE_POLICY] Write all 3 emails now, even if [DAYS_OVERDUE] means only one of them should go out today. Each email needs 2 subject line options and a ready-to-send body. 1. Day 1 overdue — friendly reminder. Assume the invoice was missed, not ignored. Short and warm. One clear payment link. No guilt and no late-fee mention. 2. Day 7 overdue — firmer, still respectful. Restate the amount, invoice number, and what it was for. Ask them to pay today or reply with a specific date they will pay. Mention [LATE_FEE_POLICY] only if a real policy was provided. 3. Day 14 overdue — final notice before you pause new work for this customer. Direct and calm. State the amount, invoice number, and payment link again. Say clearly that new work pauses until this invoice is paid. No threats, insults, legal jargon, or collections-agency language. Offer one short path if the invoice itself is wrong. Rules for every email: - Under 140 words - Put the invoice number and amount due in the first two sentences - Use [CUSTOMER_NAME] - Show [PAYMENT_LINK] as a plain URL on its own line, not "click here" - Sound like the owner of [BUSINESS_NAME], not a billing department or a collections agency - No "per my last email", "just circling back", shame, or fake urgency - End with one next step: pay at the link, or reply if something on the invoice is wrong - Sign off with a first name and [BUSINESS_NAME] After the three emails, add a one-line send guide based on [DAYS_OVERDUE]: - 1–6 days: send Email 1 today - 7–13 days: send Email 2 today (skip Email 1) - 14 or more days: send Email 3 today
