Thank you, your email address is noted. Nothing was sent, this prototype has no mail dispatch.

Basis of the text modules: Austria prescribes no particular form for a payment reminder. The generator sets the details that are customary in practice and the three levels; the deadlines are values taken from practice. The legal norms and the evidence are listed under sources and legal bases.

In brief

How do you write a payment reminder?

A payment reminder names the unpaid invoice with its number and date, the outstanding amount, the missed due date and a new payment deadline with a specific date. No particular form is prescribed. The payment reminder generator from incaseof.law writes that text in 2026 in three levels for Austria: courtesy reminder, formal reminder and final reminder.

Reminding properly

What a payment reminder in Austria has to achieve.

A reminder is not a form, it is a piece of evidence. The more clearly it identifies the claim and sets the deadline, the easier every further step becomes.

How do I word a payment reminder properly?

A reminder is right when the recipient knows exactly three things after reading it: which invoice is meant, how much is outstanding and by when he should pay. Everything else is decoration. Leave out accusations, exclamation marks and threatened consequences you do not intend to follow through. A factual tone costs nothing in effect and keeps the customer relationship intact. The Austrian Federal Economic Chamber publishes sample letters for the structure of such letters, and practice has followed them for years.

What belongs in a payment reminder

Austria prescribes no particular form for a payment reminder. In practice, though, a fixed set of details has become established, because it avoids follow-up questions and holds up in a dispute.

The details the generator puts into every letter.

DetailWhy it counts
Invoice numberTies the reminder to one invoice without ambiguity. Without it the search starts at the recipient.
Invoice dateRecords when the work was billed and makes the age of the claim visible.
Due dateThe reference point for default. Only from here is the payment overdue.
Outstanding amountStates the sum at issue, including every item you are claiming.
New payment deadlineA specific date, not "immediately". Only a date can be checked.
Payment detailsBank details and payment reference. Every hurdle removed raises the payment rate.
Contact personWho is available for questions. Many unpaid invoices are in truth open questions.

How many reminders are customary?

No particular number is prescribed. The widespread assumption that it has to be three reminders is a habit from accounting practice, not a rule. Many companies send one written reminder and then hand the claim over, because every further round costs mainly one thing: time. What the escalation looks like in full is set out in how debt collection works.

The three levels and their deadlines

The three levels differ not in content but in tone and in the consequence they announce. The generator keeps all three ready, so you do not have to write from scratch at each level.

Overview of the levels. The deadlines are values customary in practice, not prescribed periods.

LevelToneCustomary deadlineWhat it achieves
Courtesy reminderFriendly7 to 10 daysAllows for an oversight and keeps the customer relationship clean.
Formal reminderFactual and firm7 to 14 daysRecords the default and sets a new deadline that can be checked.
Final reminderFirm, without threats5 to 7 daysAnnounces the handover to a debt collection institute in factual terms.

What matters is not the length of the deadline but that it has expired before you move to the next level. A reminder pushed out before the deadline ends devalues the one before it.

What you may charge as reminder fees

Only reasonable costs that you have actually incurred may be charged. Austria has no statutory flat rate for reminder fees. That is exactly why this generator suggests no amount: an invented standard rate in the letter is open to challenge and weakens your own position. Enter what has really been incurred at your end, or leave the field empty. Late payment interest is a separate matter; the amount for your period is worked out by the late payment interest calculator.

When to hand the claim to a debt collection institute

Handing over makes sense as soon as the last deadline you set has passed without a response. Whoever keeps reminding after that loses mainly time, and with time the likelihood of the claim arriving in full goes down. What happens after the handover is set out step by step in how debt collection works, and what the collection costs is on the page about debt collection costs.

If you are in that situation right now, the pages unpaid invoice and customer not paying take you through the next steps. Companies that send reminders in volume will find the process view in receivables management.

Reminding under German law? Deadlines and default rules differ. The comparison receivables management in Austria and Germany covers the position on both sides.

No, a payment reminder is not prescribed. In practice it is still the usual first step: it documents your demand for payment, gives the customer a clear deadline and creates a clean basis for every further step.
No. Three reminders are a widespread habit, not a requirement. Many companies send one reminder and hand the claim over after that. What matters is not the number but that the claim is identified without ambiguity and that a deadline has been set.
A reminder needs the unambiguous identification of the unpaid invoice with the invoice number and the invoice date, the outstanding amount, the reference to the missed due date and a new payment deadline with a specific date. Your payment details and a contact person for questions come on top.
Only reasonable costs that you have actually incurred may be charged. There is no statutory flat rate for reminder fees. That is why the payment reminder generator from incaseof.law suggests no amount either: you enter what has really been incurred at your end.
No fixed waiting period is prescribed. In practice there are usually seven to fourteen days between two reminders, so roughly as long as the payment deadline set before was running. What matters is that the deadline you set has actually expired before the next level.
Stay factual and assume nothing. The courtesy reminder level in the payment reminder generator is worded exactly that way: it names the unpaid invoice, allows for an oversight as a possibility and asks for payment by a specific date, without accusation and without pressure.
In German. That is the legally relevant language for Austrian and German debtors, so the letter, the subject line and the payment demand are in German. The tool itself, the explanations and this page are in English.
