Unpaid client recovery

My invoice is 30 days overdue. What do I send?

Updated July 2026 · Free tool, nothing leaves your browser

The short answer

At 30 days overdue, stop sending casual check-ins and send one short written follow-up that restates the amount, names the original due date, and asks for either payment today or one exact payment date. Keep it factual. The goal at this stage is a clear written record, not pressure.

The message to send today

Enough time has passed and you have a written anchor to be more direct while staying factual.

Send today · Escalate firmly
Subject: Payment follow-up for website build
Hi Northgate Media,

I'm checking in on payment for website build. The amount still open is $2,400, and it is 30 days past due.

This follows the payment date we agreed to in writing. Please send payment today or reply with the exact payment date so I can close this out on my side.

I would like to resolve this cleanly and close the payment record.

Your position in this situation

Limited. Your position is limited, so the safest move is a clean record and a short deadline.

Send the plain reminder today and avoid threats. The goal is to create a clear written trail before deciding what to do next.

If they do not reply

  1. Today Today - send first

    Ask for payment or one exact payment date.

  2. 3 business days later Day 3 - if no clear reply

    Move from reminder to firm deadline.

  3. 7 days after today Day 7 - final written follow-up

    Send the final written follow-up and stop the open-ended thread.

Day 3 - if no clear reply
Subject: Follow-up: $2,400 still open
Hi Northgate Media,

I have not seen payment or a clear payment date for website build.

Amount due: $2,400
Status: 30 days past due

Please send payment or confirm the payment date within 24 hours. Since the work has already been delivered, I want the next step confirmed in writing.
Day 7 - final written follow-up
Subject: Final follow-up: $2,400 unpaid
Hi Northgate Media,

This is my final written follow-up on the unpaid balance for website build.

Amount due: $2,400
Status: 30 days past due

Please send payment or reply with a clear payment date within 48 hours. If I do not hear back, I will stop treating this as an active project thread and organize the record before deciding the next practical step.

This note is meant to keep the facts clear and give us one more chance to resolve it directly.

Questions people ask about this

Should I add a late fee at 30 days overdue?

Only if a late fee was agreed in writing before the work started. Introducing one now usually invites a dispute about the whole invoice instead of getting the balance paid. If it was agreed, state it as a fact, not a threat.

How long should I wait before following up again?

Three business days is enough for a first follow-up after a written ask. If there is still no payment and no specific date, move to a final written follow-up around seven days after that, then stop chasing casually and organise the record.

Is 30 days overdue late enough to escalate?

It is late enough to be firm in writing, but escalation works better once you have a clear paper trail showing the amount, the agreed date, and at least one unanswered written request for payment.
