# Payment Reminder Email for Invoices Nobody Answered: Zentor watches the invoices you already sent, and drafts a friendly payment reminder email when the due date passes with no reply.

Source: https://zentor.ai/use-cases/payment-reminder-email

A payment reminder email drafted in the original thread. Zentor does not create invoices or take payment.

## Prompt

```text
Each morning, find invoices I emailed that have no reply after the due date. Draft a polite payment reminder in the same thread. Do not send anything.
```

Variations:

- **Friendly, then firm**: For invoices 7 days overdue, draft a friendly payment reminder email. For invoices 21 days overdue, draft a firmer one that restates the amount and the due date.
- **One client**: If Northline has not replied to invoice 1043 by Friday, draft an overdue invoice email in that thread.

## How it works

1. **Point it at invoices you already sent**: Zentor does not create or send invoices. It reads the invoice emails in your sent mail.
2. **It waits the number of days you set**: A common first nudge is a few days after the due date. The second is firmer. You pick both.
3. **You send the draft**: The overdue invoice reminder email lands in the original thread. You read it, edit it, and send it.

## Which invoices to chase

- A friendly first reminder: A friendly payment reminder email a few days after the due date, still assuming good faith.

## FAQ

### How do you politely remind a client to pay?

Restate the invoice number, the amount, and the due date, and assume the first miss was an oversight. Zentor drafts that polite payment reminder email in the original thread for you to send.

### How many days after the due date should I send a reminder?

A few days for the first note is a common default. Wait longer before the firm one. You set both numbers.

### Can Zentor send invoices?

No. It does not create invoices, send them, or take payment. It drafts a payment reminder email about an invoice you already emailed.

### How to ask for payment in an email?

Name the invoice, the amount, and the date, and say how to pay. That is the whole note. Zentor drafts it from the thread.

### How to ask for payment professionally in an email?

Keep it short, use the invoice number, and leave out apologies. A professional payment reminder states the facts and the next step.

### How to send a payment reminder email?

Open the original invoice thread and reply there, so the client has the invoice above your note. Zentor saves that reply as a draft.

### How to reply to a payment reminder email?

If you are the one who received it, reply in the same thread with the date you will pay or the reason you cannot. Zentor can draft that reply for you to send.

### What if a client is not paying an invoice?

Send the reminder, then a firmer one, and keep both in the same thread. Chasing beyond that, including a lawyer, is your call. Zentor only drafts the emails.

### How to ask for upfront payment by email?

Say the amount, when you need it, and that work starts after it arrives. Zentor drafts it. Your billing tool still creates the invoice.
