If an invoice stays open after the due date, a friendly payment reminder usually comes first, followed by one or more formal reminders. Austria does not prescribe a fixed number of reminders — what matters are clear deadlines, traceable amounts, and a documented process.
Legally, one reminder is generally enough in Austria; in practice, a staged process has become standard: first a friendly nudge, then a clear demand, and finally an announcement of further steps. Each business sets its own intervals.
| Stage | Typical timing | Focus |
|---|---|---|
| Payment reminder | about 1 week after due date | Friendly note with a new deadline |
| Formal reminder | about 2 to 3 weeks after due date | Clear demand, possibly reminder fees |
| Final notice | about 4 to 6 weeks after due date | Last deadline, note on collection or court |

An effective reminder points unambiguously to the open invoice: invoice number, invoice date, original due date, and open amount. It adds a new payment deadline, the bank details, and a note on what follows if payment is missed again.

Take partial payments already received into account
