Payment Reminder Generator.
A payment reminder is a short, polite message that tells a customer an invoice is due or overdue and asks for payment. Enter the invoice details, pick the stage and tone, and this tool writes an email with a subject line plus a short WhatsApp or SMS version, ready to copy.
The message updates as you type and nothing is sent anywhere: copy it into your own email, WhatsApp or SMS. Read it before sending and only mention late fees or further action that your agreement and local law allow.

What you'll get.
A real example of what this tool produces. Run it above with your own inputs.
Most late invoices are late because someone forgot, the invoice went to the wrong person or it is sitting in an approval queue. A short, clear reminder fixes the majority of them, and the wording matters: too soft and it is ignored, too sharp and you damage a relationship over what was an oversight.
This generator writes the reminder for the stage you are at. There are six stages: a friendly reminder before the due date, due today, about 7 days overdue, about 14 days overdue, 30 days or more overdue and a final notice. Each comes in three tones: friendly, professional and firm. You get an email subject line, the email itself and a short version for WhatsApp or SMS, all filled in with the invoice number, amount, due date and the actual number of days overdue.
The tool is free, needs no sign-up and runs in your browser, so nothing you type is uploaded. It comes from Neweb, the AI website builder for small businesses, which has a free plan and paid plans from $9/month billed yearly ($19 month-to-month). Reminders work best when paying is easy, so put your payment details on the invoice and on your website.

Why this matters for your business
Cash flow depends on it. Work you have delivered but not been paid for is money you are lending to your customer. A consistent reminder routine shortens the wait without making each chase a personal confrontation.
A paper trail matters if it goes further. Dated, polite reminders that state the invoice number, amount and due date show that you asked clearly and gave the customer time to pay.
What to include in a payment reminder, and why
- The invoice number and amount. The person reading may not be the person who ordered; make it easy to find in their system.
- The due date and how overdue it is. Facts, not adjectives. "Due on 3 November, now 9 days overdue" is clearer than "seriously late".
- One clear request. Pay, or reply with a payment date.
- How to pay. Bank details reference or a payment link, so there is no reason to write back and ask.
- A way out for honest mistakes. "If you have already paid, please ignore this" keeps goodwill.
- In a final notice, a date and a consequence. Say what you will do and when, and only threaten what you are entitled to do and prepared to do.
A simple reminder schedule
A common routine is a friendly reminder a few days before the due date, a note on the day, follow-ups at about one week and two weeks overdue, a firmer message at 30 days and then a final notice with a deadline. Adjust it to your payment terms and to how well you know the customer. If you have not sent the invoice yet, create it with the invoice generator.
Tips for better results
- Send the reminder to the person who pays invoices, and copy your usual contact.
- Attach the invoice again so nobody has to search for it.
- Start friendly. Move to a firmer tone only when earlier reminders have gone unanswered.
- Pick up the phone once before a final notice; a two-minute call often uncovers a simple problem.
- Only mention late fees or interest if your contract or invoice terms set them out and the law where you trade allows them.
- Keep a note of every reminder and the date you sent it.
Example
A real-world walkthrough
Northlight Design Studio sent invoice INV-1042 for $1,250.00, due on 3 November 2026. On 12 November it is still unpaid. Elena enters the details, and the tool counts 9 days overdue and suggests the "about 7 days overdue" stage. In the friendly tone, the email opens "Hi David," explains that the invoice was due on 3 November 2026 and does not seem to have come through, and asks when she can expect payment.
Two weeks later there is still no reply, so she switches to "about 14 days overdue" and the professional tone. The subject becomes "Second reminder: invoice INV-1042 is 23 days overdue" and the message asks for payment now or a confirmed payment date.
Frequently asked questions
How do you politely ask for an overdue payment?
State the facts and make one request. Give the invoice number, the amount and the due date, say that it appears to be unpaid, ask for payment or a payment date, and say how to pay. Add a line such as "if you have already paid, please ignore this" so that an honest mistake does not feel like an accusation. The friendly tone in this tool follows that pattern.
When should I send the first payment reminder?
Many businesses send a short courtesy reminder a few days before the due date and another on the day itself. If the invoice becomes overdue, a follow-up within the first week is reasonable. The earlier and more routine your reminders are, the less awkward they feel to both sides.
How many reminders should I send before a final notice?
There is no fixed number. A typical sequence is reminders at around 7, 14 and 30 days overdue, then a final notice with a specific pay-by date. If the customer replies and agrees a payment date, pause the sequence and confirm the date in writing.
Can I charge a late fee or interest on an overdue invoice?
That depends on your contract or invoice terms and on the law where you and your customer are based. Some countries give businesses a legal right to interest on late commercial payments and others only allow what was agreed in advance, often with limits. This tool does not calculate or recommend a fee; it only inserts your own wording if you provide it. Check your terms and local rules before mentioning a charge.
What should a final notice say?
That it is the final reminder, which invoice and amount it concerns, how overdue it is, the date by which you need payment, and what you will do if that date passes, such as pausing work or starting formal recovery. Keep it factual, and state only steps you are entitled to take and intend to take. If the amount is significant, get advice before you send it. This tool provides general templates, not legal advice.
Does this tool send the reminder for me?
No. It only writes the text, in your browser. Nothing is uploaded or sent. Copy the email into your own email app, or copy the short version into WhatsApp or SMS.
