Unpaid client recovery

They say they never received my invoice

Updated July 2026 · Free tool, nothing leaves your browser

The short answer

This is sometimes genuine and sometimes a reset button that restarts your payment clock. Handle both the same way: resend immediately, keep the original invoice date and number visible rather than reissuing it fresh, and ask them to confirm receipt in writing. Confirmation is what stops the same answer working twice.

Subject: Payment follow-up for landing page
Hi Redmond Partners,

I'm checking in on payment for landing page. The amount still open is $1,600, and it is 26 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.

Hi Redmond Partners,

I have not seen payment or a clear payment date for landing page.

Amount due: $1,600
Status: 26 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: $1,600 unpaid
Hi Redmond Partners,

This is my final written follow-up on the unpaid balance for landing page.

Amount due: $1,600
Status: 26 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 reissue the invoice with a new date?

No. Resend the original with its original date and number, and note the date it was first sent. Reissuing it fresh hands them a new payment window and erases how late the payment already is.

How do I stop this happening again?

Ask for written confirmation of receipt on every invoice, and send to a named person rather than a generic accounts address where possible. A one line reply confirming receipt closes this route entirely.

What if they claim it went to spam?

Treat it as plausible and act accordingly: resend, ask for confirmation, and follow up through a second channel they already use with you. Then set your written record so the claim cannot be repeated.
