Late payment email template: a polite 4-step sequence

You want to get paid without sounding desperate, and without losing a client you like. Good news: most late invoices are not a fight. They are an email that got buried, an approval stuck with the wrong person, or a client waiting for someone to ask. A short, polite sequence on a fixed schedule gets most of them paid and keeps the relationship intact.

Below are four emails you can send today. Copy them, change the bracketed bits, and you will never again stare at a blank "just following up" draft. If you would rather not send them yourself, they can go out for you, in your name.

How the sequence works

Email	When to send	Goal
1. Friendly reminder	On the due date	Make paying easy
2. Past-due reminder	7 days late	Confirm they saw it, invite questions
3. Direct request	15 days late	Get a payment or a firm date
4. Accounts review notice	30 days late	Formal last step before you decide what is next

Always include the invoice number, amount, original due date, and a pay link.
One clear request per email.
Send from your own business address and sign with your name.
Give a way to reply if something is wrong with the invoice.
Stop the sequence the moment they pay or reply with a plan.
Never threaten anything you will not do, and never add fees your terms do not allow.

What not to write

"Final notice" on the first or second email. Save firm language for when it is true.
Threats of legal action, credit reporting, or collections you do not plan to pursue.
Late fees that are not in your contract or invoice terms.
Group emails that show one client's balance to another.

This page is general guidance, not legal advice. These templates are for business-to-business invoices only. Some states regulate how even commercial debts are collected, so check with your own advisor if you are unsure.

Get paid without sending these yourself

Writing these is the easy part. Remembering to send email 3 on day 15 for nine different clients, in your busiest week, is the hard part.

Hand that part off. Upload your aging report once, approve the wording, and every late client hears from you on schedule, with your pay link, until they pay. You see what came in. Your first late invoice is free.

FAQ

How many reminders should I send for a late invoice?

Four over 30 days is a reasonable default: one on the due date, then at 7, 15, and 30 days late. Adjust for your terms and the client.

Should I call instead?

For large balances, a call after email 3 often helps. Email keeps a written record either way.

Is it rude to send a reminder on the due date?

No. Many clients pay from reminders. A due date note framed as "here is the link" reads as service, not pressure.
