Most late invoices are not refusals to pay. They are invoices stuck in an accounts-payable queue, sent to someone on holiday, or sitting under a purchase order nobody raised. A good reminder sequence fixes those quickly and keeps the relationship intact, while making it clear that you track your invoices and that silence has consequences.
This page gives you five short emails, each ready to copy into your mail client, timed from a few days before the due date to 30 days late. The tone tightens with each step, from a helpful heads-up to a clear statement of next steps.
TL;DR
The payment reminder email templates are a five-step sequence: a friendly note 3–5 days before the due date, a same-day reminder, a firmer follow-up at 7 days late, a 14-day email that names contract terms and pauses work, and a 30-day email that sets a deadline before a formal final notice. Each email restates the invoice number, amount, and payment link.
What's inside
- Email 1: before the due date — a friendly heads-up with the invoice reattached.
- Email 2: on the due date — a short, neutral reminder that payment is due today.
- Email 3: 7 days late — asks for a payment date and offers to resolve any issue.
- Email 4: 14 days late — references the payment terms in your contract and any pause in work.
- Email 5: 30 days late — sets a firm deadline and says a formal notice will follow.
- Subject lines — each one names the invoice number and status, so it is easy to forward to accounts payable.
- Partial-payment follow-up — a short note for when only part of the balance arrives.
- Phone call script — a short script for the call between emails 3 and 4.
When to use it
Use the sequence for every unpaid invoice, starting before it is due. It works for project, milestone, and retainer invoices. Make sure the original invoice was clear first: a missing PO number or wrong billing contact is the most common reason for delay, and the invoice checklist catches those.
After the fifth email, switch to the overdue invoice final notice, a formal letter that sets out the outstanding amount and the steps you intend to take. If the issue is that the client disputes the work, not the timing, stop the sequence and talk to them before sending more reminders.
How to run the sequence well
Send to the right person. For companies, copy the accounts-payable address from the start. Your project contact often has no power to release a payment.
Keep the facts identical in every email. Invoice number, amount, original due date, and the payment link. Changing details between emails gives a slow payer a reason to restart the clock.
Make paying the easiest option. A card or PayPal link removes the "we only pay by bank transfer on the 15th" excuse for small amounts.
Add one phone call. Around day 10, a five-minute call often does more than two emails. Ask a direct question: "Is there anything stopping this from being paid?"
Use only terms you have. If your contract does not include late fees or interest, do not threaten them. If it does, quote the clause. The getting paid as a freelancer guide covers how to add these terms to future contracts.
Customize it in your COLO workspace
In COLO invoicing, you can email the invoice directly from your workspace, and clients can pay by card (Stripe) or PayPal from the client portal. Partial payments are recorded against the invoice, which helps when a client pays in installments after a reminder.
COLO does not send reminders for you, so keep this sequence as a saved snippet in your email client and use the invoice and payment reports to see which invoices are outstanding each week.
Common mistakes
- Waiting until the invoice is 30 days late to say anything. The pre-due reminder prevents most late payments.
- Apologizing for asking. You did the work. "Just a friendly reminder" is fine; "sorry to bother you" is not.
- Long emails. Three to five sentences per reminder. Long emails get skimmed.
- Threatening action you will not take. Only state next steps you are prepared to follow through on.
- Starting new work for a client with an overdue invoice. Hold new work until the account is current.
FAQ
Q: When should I send the first payment reminder?
Three to five days before the due date. A short, friendly note at that point catches invoices that went to the wrong inbox or are waiting for approval, before they become late.
Q: How many reminders should I send before taking further action?
Four or five is common. A pre-due reminder, one on the due date, and follow-ups at 7, 14, and 30 days late, with a phone call added somewhere around day 14.
Q: Should I mention late fees in a reminder?
Only if your contract includes them. Mention them first at around 14 days late, and quote the exact clause rather than inventing a figure.
Q: How do I write a polite payment reminder?
Keep it short, include the invoice number, amount, and due date, attach the invoice again, and give one easy way to pay. Assume an honest mistake until the facts say otherwise. More tactics are in how to get clients to pay invoices on time.
Q: What do I do after 30 days?
Pause any ongoing work if your contract allows it, call the client, and if there is still no payment, send a formal final notice before considering collections or small claims.
