Unpaid invoice reminder email
Four copy-paste reminder templates for unpaid invoices — from a friendly nudge to a firm final notice. Includes a timing guide and common mistakes to avoid. Template 1 — Friendly nudge (1–3 days overdue): a short, warm message checking in on the invoice. Assumes a genuine oversight on the client's part. Template 2 — Polite follow-up (5–7 days overdue): references the invoice number, amount, and due date clearly. Includes the payment link and asks for a response if there's an issue. Template 3 — Firm notice (14–21 days overdue): direct and factual. States the invoice is now significantly overdue and requests payment or communication within a specific number of days. Template 4 — Final notice (30+ days overdue): clear statement of the overdue amount, a specific payment deadline, and note of potential next steps if payment is not received. Timing guide: send the first reminder 1–3 days after the due date, the second after 7 days, the third after 14–21 days, and the final notice at 30 or more days. Always reference the invoice number and include a direct payment link to remove friction. Duevero Pro automatically sends email reminders for overdue invoices — so you never have to write a follow-up manually.
