Ten emails for when an invoice is late. They stay polite on purpose. Most late invoices are buried, stuck in a process, or waiting on a question — not a refusal to pay.
Send one email, then wait. A few quiet days beat three tones in the same afternoon.
Stay in the original thread and attach the invoice PDF again.
Fill every bracket. Read it once more and delete any line that still has a bracket.
Use the pause email only if you will actually stop new work. Do not send it as a bluff.
On the final notice, keep one closing and delete the other two, plus the instruction line.
If a date is promised, do not write again until that date has passed.
These are reminders you can send yourself. They are not a contract, a court filing, or advice from a lawyer or an accountant. Only say you will pause work, hand an invoice to someone else, or start a dispute if you will actually do that.
01
Friendly reminder
When to send. Two or three days after the due date, when you have heard nothing.

Resending invoice [Invoice number] for [Amount]

It is for [Project]. The amount is [Amount], and it was due on [Due date]. The PDF is attached again. The same copy is here: [Invoice link]. Payment link: [Payment link].

Anything unclear?
When to send. When silence might mean a question about the invoice, not a missed email.
Subject
Anything look off on invoice [Invoice number]?
Body
Hi [Client name],
I have not seen payment for invoice [Invoice number] ([Amount], due [Due date]), and I want to check whether something on it is unclear.
If a line, a date, or the total looks wrong, tell me. I will correct it and send a revised invoice. If the invoice is right and it is waiting on a process, a short note on where it sits is enough.

Ask for a date
When to send. When you need a date you can plan around, and you are willing to stop chasing until that date.
Subject
When should I expect invoice [Invoice number]?

I am planning the next few weeks and I need a date for invoice [Invoice number].
Amount: [Amount]
For: [Project]

Please reply with the date you expect to pay it, even if that date is later than the due date. I will confirm it, and I will not chase you before then.

A split is fine
When to send. When the total may be the blocker, and you are willing to take the money in parts.
Subject
Invoice [Invoice number] — we can split [Amount]
Body
Hi [Client name],
If the full [Amount] on invoice [Invoice number] is what is holding this up, we can split it.
One way that works: half now, and the rest on a date you name within 30 days. If another split is easier, propose it. I will reply with a short confirmation of whatever we agree. The original invoice stays the record of the full amount.
Invoice: [Invoice link]
Pay: [Payment link]
If the amount itself is wrong, say so and I will fix the invoice instead of splitting it.

Holding further work
When to send. When you have decided to stop new work until this invoice is paid.
Before you send. Send this only if you will actually pause. Take it out of the sequence if you are still willing to keep working.
Subject
Holding further work on [Project] until invoice [Invoice number] is paid
Body
Hi [Client name],
I am pausing any further work on [Project] until invoice [Invoice number] is paid.
What is already delivered stays delivered. I am not undoing it. I am also not starting the next piece until [Amount] is settled. The invoice was due on [Due date].
Invoice: [Invoice link]
Pay: [Payment link]
If a pay date is already set, reply with it and I will keep that date. Otherwise I will wait to schedule anything new.

The facts, in one place
When to send. Two weeks or more overdue, when the thread is long and you want one message they can forward.
Subject
Invoice [Invoice number] is still open — [Amount]
Body
Hi [Client name],
I am putting the details in one place so they are easy to forward to whoever pays this.
Invoice number: [Invoice number]
Amount: [Amount]
For: [Project]
Due: [Due date]
Invoice: [Invoice link]
Pay: [Payment link]
I have not received payment, and I have not received a note about a problem with the invoice. If someone else should have it, send me their email and I will write to them and copy you.
If you have already paid, tell me the date and the method so I can match it.

One specific reply
When to send. When you want a single concrete answer, and you will keep your word about staying quiet until that date.
Subject
Please send a pay date for invoice [Invoice number]
Body
Hi [Client name],
I only need one thing from you on invoice [Invoice number]: a pay date.
The amount is [Amount], for [Project], originally due [Due date].
Invoice: [Invoice link]
Pay: [Payment link]
Reply with a date. If that date passes without payment, I will write again. I will not send extra reminders between now and the date you give me.

Subject
Invoice [Invoice number] — one note left after this
Body
Hi [Client name],
This is the reminder before a final notice on invoice [Invoice number].
Amount: [Amount]
For: [Project]
Original due date: [Due date]
Invoice: [Invoice link]
Pay: [Payment link]
I will send that final notice on [Final notice date] if I have not received payment or a reply. If something on the invoice is wrong, I need to hear it before that date so I can correct it. A pay date before then is welcome too.

Final notice
When to send. The last email you will send about this invoice. Do not send it if you expect to keep reminding them.
Before you send. Keep one closing. Delete the other two, and delete the instruction line, before you send.
Subject
Final notice — invoice [Invoice number] for [Amount]
Body
Hi [Client name],
This is the last reminder I will send for invoice [Invoice number].
Amount: [Amount]
For: [Project]
Original due date: [Due date]
Invoice: [Invoice link]
Pay: [Payment link]
Earlier notes in this thread asked for payment, or for a correction if the invoice was wrong. I have not received either.
Please pay by [Final notice date], or reply before then if the invoice needs a fix.
Choose one closing below. Delete the other two. Delete this instruction line before you send.
Closing A — if you will stop writing and stop new work:
After [Final notice date] I will close my file on this invoice as unpaid, and I will not schedule new work. I will not send another reminder.
Closing B — if a bookkeeper or a collector will actually take it:
After [Final notice date] I will hand the invoice to [Bookkeeper or collector] to collect. I will not send another reminder myself.
Closing C — if you will use a dispute process and you mean it:
After [Final notice date] I will treat the amount as still owed and I will use the dispute process available to me where I work. I will not send another reminder first.
