Final Demand for an Unpaid Invoice: Template + What Comes Next

Short answer: a final demand is the last email before you escalate. Send it once an invoice is ~30 days overdue and earlier reminders have gone unanswered. State the facts, add the statutory interest you're owed, set a firm deadline, and say what happens next. Template below.

When to send it

The final demand is the last step of a calm chase sequence, not the first contact. By the time you send it you should already have sent a pre-due reminder, a due-date note, and overdue notices at 7 and 14 days. If those produced nothing, sending more of the same rarely works — escalate the tone and the stakes.

The final-demand template

Subject: Invoice {INV-014} — formal payment reminder

Hi {name} — cc'ing {their manager},

Invoice {INV-014} ({€4,500}, issued {2 May}, due {16 May}) is now 30 days overdue. I've sent {three} reminders without a response on payment timing.

Under the EU Late Payment Directive 2011/7/EU I'm entitled to statutory interest of 8% above the ECB reference rate plus a €40 recovery fee. The updated balance, including interest accrued to date, is {€4,560}.

Please arrange payment by {date — e.g. 7 days from now}. If I haven't received it or heard from you by then, I'll begin recovery through {small claims / a collections agency} without further notice.

I'd much rather resolve this directly — please let me know if there's a genuine blocker.

Regards, {your name}

If they still don't pay: escalation options

• UK (England & Wales): a letter before action, then Money Claim Online for claims up to £100,000. Statutory basis: the Late Payment of Commercial Debts (Interest) Act 1998.
• Cross-border within the EU: the European Small Claims Procedure (claims up to €5,000) and the European Order for Payment — both designed for pursuing a debtor in another member state without hiring a lawyer.
• Domestic EU claims: most countries have a simplified payment-order or small-claims track — check your national court's process.
• Collections agency: an option if you'd rather not handle it yourself; expect to give up a percentage of the recovered amount.

FAQ

What is a final demand for payment?

It's the last reminder before you escalate — a formal, dated message stating the invoice details, that previous reminders went unanswered, the statutory interest now due, and a clear deadline after which you'll start a small-claims or collections process. It signals the chase is over and consequences begin.

What is a letter before action?

A letter before action (also called a letter before claim) is the formal notice you send before starting court proceedings, giving the debtor a final, specific chance to pay. In the UK it's effectively expected by the courts before a small claim. Across the EU it serves the same purpose: documented proof you tried to resolve it first.

Can I take a client to small claims for an unpaid invoice?

Yes. For domestic debts, most countries have a simplified small-claims track (e.g. Money Claim Online in England & Wales). For cross-border B2B debts within the EU, the European Small Claims Procedure and European Order for Payment let you pursue claims in another member state without a lawyer. This is general information, not legal advice — check your jurisdiction.
