The unpaid invoice

Your three escalating chase messages will appear here once generated.

Chasing a customer for money is one of those jobs everyone puts off, partly because it's awkward and partly because it's hard to know how firm to be on day 3 versus day 45. This tool writes three escalating versions of the same chase from one set of invoice details: a friendly nudge that assumes it's simply been missed, a firmer reminder once it's genuinely overdue, and a final notice that's direct without threatening anything you haven't actually decided to do. Fill the details in once, pick the version that fits how overdue it is, and send it.

Why the tone should change as the days go on

Sending a stern final-notice tone on day 3 annoys a customer who simply forgot, and sending a soft nudge on day 60 makes you look like you're not serious about being paid. Matching the tone to how overdue the invoice actually is keeps the relationship intact for the invoices that get paid on a gentle reminder, while still giving you something properly firm to send when a customer is clearly not going to pay without being pushed.

A worked example

Details in: customer "Mr Johnson", invoice "INV-1042", amount "£450", 14 days overdue. Friendly nudge out: "Hi Mr Johnson, just a quick note to flag that invoice INV-1042 for £450 doesn't seem to have been paid yet — it's easily done if it's slipped through, so let us know if you need anything from us to sort it." The firmer reminder and final notice versions keep the same facts but tighten the language and ask directly for a payment date.

What this isn't

This is a first draft, generated from the details you type in — it doesn't know your payment terms, whether you charge late interest, or anything about the customer relationship, so read each version before you send it. It won't invent a specific legal threat or an interest figure you didn't tell it to include, but it's a payment-chasing message, not legal correspondence, and it isn't a substitute for proper debt-recovery advice if an invoice ends up genuinely contested. Treat it as a fast draft that still needs your own eyes on it before it goes to a customer.
