Your law, your interest

Your contract is usually governed by your German or Austrian law; best to state that in your quote and your terms. For business clients, German law gives you 9 percentage points above the base rate, so 10.52% for the second half of 2026, plus a EUR 40 flat fee. Austrian law gives you 9.2 points, so 10.73%, also with EUR 40. The late-payment interest calculator works out the exact amount.

The three templates

Pick where your business is based, Germany or Austria, above each template: the rate, the law and the flat fee are already filled in. You only replace the bracketed placeholders.

Stage 1: Payment reminder
Subject: Payment reminder — invoice [number]

Dear [Mr/Ms surname],

I hope you are well. This is a friendly reminder that invoice [number] of [invoice date] for [EUR / NOK] [amount] was due on [due date] and is still open on our side.

If the payment is already on its way, please disregard this message. Otherwise, please pay the amount by bank transfer to:

Account holder: [your company]

Reference: [invoice number]

Kind regards,
[your name]
Stage 2: Second reminder
Subject: Second reminder — invoice [number], now overdue

Dear [Mr/Ms surname],

Despite our reminder of [date], invoice [number] of [invoice date] for [EUR / NOK] [amount] remains unpaid. The payment is now [x] days overdue.

Please settle the outstanding amount by [new date]. Under our terms and German law (§ 288 BGB), default interest of 10.52% per annum applies from [date default began], plus a flat fee of EUR 40 for recovery costs.

IBAN: [IBAN] · BIC (SWIFT): [BIC] · Reference: [invoice number]

If there is a problem with this invoice, please contact me directly so we can sort it out.

Kind regards,

Stage 3: Final notice
Subject: Final notice — invoice [number]

Dear [Mr/Ms surname],

Invoice [number] of [invoice date] for [EUR / NOK] [amount] is still outstanding despite two reminders, most recently on [date].

Outstanding amount:                    [EUR / NOK] [amount]
Default interest ([x] days at 10.52%): [EUR / NOK] [interest]
Flat fee for recovery costs:           EUR 40.00
Total now due:                         [EUR / NOK] [total]

Please transfer the total to IBAN [IBAN] by [date]. If we have not received payment by then, we will hand the claim over for collection, and any further costs will be added to your account.

Kind regards,
[your name]

What is different with clients in Norway

  • Not in the EU, no VAT line. Norway is in the EEA but not in the EU. Services to Norwegian businesses carry no German or Austrian VAT, and there is no EU VAT ID. That is why the templates have no VAT ID and no reverse-charge line.
  • Put a date on the invoice. Without an agreed due date, interest in Norway only runs 30 days after a written payment demand, and by email only if your client expressly accepted email. A fixed date on the invoice saves you that.
  • 60 days at most. Between businesses, Norway allows payment terms of up to 60 days, unless you expressly agree otherwise.
  • Kroner or euros. Norway pays in kroner (NOK), and euros work by agreement. Euros from Norway arrive by SEPA with no conversion. Kroner come as an international transfer, and the rate and fees decide how much reaches you.
  • Fellesferie in July. In July many Norwegian companies take a few weeks of summer holiday at the same time. If the deadline falls in that period, send the reminder at the end of June instead.

Frequently asked questions

Can I send a client in Norway a payment reminder in English?

Yes. English is common in Norwegian business. What matters is that the reminder is clear: invoice number, amount, deadline and bank details.

How much interest can I charge?

Under German law 10.52% a year, under Austrian law 10.73%. On top comes a EUR 40 flat fee (as of the second half of 2026). If your contract uses your client's law, their rules apply.

What payment terms are allowed in Norway?

At most 60 days between businesses, unless you expressly agree otherwise. Put a fixed due date on the invoice.

Does a VAT ID belong in the reminder?

No. Norway is not in the EU, so there is no EU VAT ID and no reverse-charge note. Invoice number, amount and bank details are enough.
