Sample Rescue Pack

Built from a fictional situation so you can see the format: an ongoing client, invoice 21 days overdue, one reminder already sent, firm tone. Your real pack is personalized to your own client, invoice, and tone.

3-email sequence

Reminder

Subject: Following up on Invoice INV-1042

Hi Jordan, I hope things are going well on your end. I wanted to follow up on invoice INV-1042 for $2,500.00 — I sent a reminder last week and it's now 21 days past the due date without payment or a note back. Since we've worked together on a few projects now, I want to assume this slipped through rather than anything else. Could you confirm today when I can expect payment, or let me know if something on your end needs sorting out first? Thanks for keeping this moving. Best, [Your name]

Firm follow-up

Subject: Invoice INV-1042 is now 21 days overdue — please confirm today

Hi Jordan, This is my second note on invoice INV-1042 for $2,500.00, now 21 days overdue with no response to my last reminder. I need a firm payment date today. Per the terms on the invoice, a late fee begins accruing the longer this remains outstanding, and I'd rather resolve this directly than have to apply it. If there's a hold-up on your side, tell me what it is and I'll work with you — but I do need this paid this week. Regards, [Your name]

Final notice

Subject: Final notice — Invoice INV-1042, 21+ days overdue

Hi Jordan, This is a final notice for invoice INV-1042 ($2,500.00), now well past due despite two prior reminders. I need payment in full within 7 days of this email. If I don't receive payment or hear from you by then, I'll apply the late fee specified in our agreement and will need to pause any further work until this is settled. I'd much rather keep our working relationship on good terms, so please reach out today if anything is preventing payment. Regards, [Your name]

Late fee clause (for future contracts)

Late Payment Fee. Invoices not paid within 30 days of the invoice date accrue a late fee of 1.5% per month (18% annually) on the outstanding balance, calculated daily from the due date until paid in full. This clause takes effect only if included in the signed agreement or invoice terms and accepted by the client in advance — check your local law on maximum allowable rates before using it.

Negotiation script (call/video)

Opening: "Hi Jordan — thanks for hopping on. I wanted to talk through invoice INV-1042 directly rather than keep emailing back and forth." State the fact: "It's 21 days past due and I haven't been able to get a firm date, so I wanted to check in live." Ask, then listen: "Is there something on your end holding this up — budget timing, an approval step, anything I should know?" Anchor an outcome: "What I need today is a specific payment date I can count on. Can we agree on one now?" If they stall: "I understand things come up. To keep this fair to both of us, let's put it in writing — a date, and if it slips again we'll apply the late fee already in our agreement." Close warm: "I want to keep working together, so let's get this settled and move forward."

Next steps

Send the firm follow-up email today if you have not already had a live conversation.
Get a specific payment date in writing (email or text), not just a verbal promise.
If the date passes, send the final notice and apply the late fee clause if your contract allows it.
For new projects with this client, add the late fee clause to the contract before work begins.

Why not just use an invoice generator?

They stop at sending

Invoice generators (including free ones) help you create an invoice. They don't help you when the client goes quiet after the due date.

Built for the awkward part

Invoice Rescue is built for the moment payment is already late — reminder emails, a late fee clause, and a negotiation script for the actual conversation.

No signup, pay once

The calculator and templates are free with no account. The AI Rescue Pack is a single $9.99 payment, not a subscription.

Questions

Are the calculator and templates really free?

Yes. The late fee calculator and the 3-step reminder email templates run entirely in your browser, with no signup and no payment required. You only pay if you choose to unlock the AI Rescue Pack for a personalized email sequence and negotiation script.

Is this a subscription?

No. The AI Rescue Pack is a single one-time payment of $9.99. There is nothing recurring, no account, and no card stored for future billing.

Is the late fee calculator legal advice?

No. It provides a mathematical estimate only, based on the rate you enter. Whether you can legally charge a late fee, and at what rate, depends on your contract and your local law. Check your contract or consult an attorney before applying a late fee.

What if the AI Rescue Pack doesn't help?

Every purchase is covered by a 7-day money-back guarantee. If it isn't useful, contact support for a refund.
