English payment demand for a Polish business: template

An English payment demand for a Polish B2B invoice should identify both parties, the debt, its original due date, the outstanding principal, currency and payment instructions. Deduct correctly allocated payments and adjustments before sending it. Use the editable wording below, then check the partial-payment example and delivery details.

This guide concerns overdue invoices between businesses operating in Poland where Polish law governs the payment obligation. English is the communication language; using it does not itself change the governing law. This is not a UK court template or a parking-charge demand. We checked the rules and Norman features on 9 November 2026.

Should you call it a reminder or a demand?

Payment reminder usually describes an initial follow-up after the due date. Demand for payment or Formal demand for payment communicates a firmer request. Add final only when that accurately describes your process. The title does not make the letter a court judgment or start enforcement.

Help the recipient identify the matter from the subject line: include the invoice number and your business name. If you normally communicate in English, continue in English, while preserving the parties' legal names. Explain a Polish NIP as a “Polish tax identification number (NIP)” if needed.

If the customer never received the invoice or reports an error, address that first. Stronger wording cannot resolve a disagreement about what was supplied or the amount owed. Keep the accounting question and your choice of tone separate.

What should you check before entering the amount?

Gather the invoice, contract or order, credit notes and payment history. For a Polish sole proprietorship, or JDG, use the entrepreneur's details shown in the documents. For a sp. z o.o., identify the company that contracted with you, rather than automatically addressing its shareholder as the debtor.

Check these five items:

1. Basis of the debt. Record the invoice number and a short description of the supply. Keep evidence that you delivered the goods or services.
2. Due date. Check the agreed payment date and any later arrangements. The issue date is not a substitute.
3. Receipts. Review the bank account, partial payments and transfers covering several invoices. Clarify an ambiguous payment reference.
4. Balance changes. Account for agreed credit notes and other settlements. Separate an undisputed amount from items the customer contests.
5. Recipient and bank details. Use the correct address and verified payment instructions. Avoid accidentally changing the bank account while adapting a template.

Outstanding principal is not the same as principal plus interest and recovery costs. Show additional amounts separately with their basis and calculation. The sample below requests principal only, making it easier to verify without inserting unassessed fees.

English payment demand template

This is an original working template. Replace every bracketed field, remove anything inapplicable and attach the documents mentioned. Write dates unambiguously, for example “20 November 2026”. The final wording must match your contract and the actual account balance.

Subject: Demand for payment: invoice [invoice number], [creditor name]

Date: [date]

From: [creditor legal name, address and NIP]

To: [debtor legal name, address and NIP]

Dear [name or Accounts Payable Team],

We request payment of the outstanding principal of [amount and currency] under invoice [number], issued on [date], for [description of goods or services / agreement reference]. The original payment due date was [date].

Our records as of [date] show:

Invoice total: [amount and currency].

Payments and agreed adjustments credited to this invoice: [amount and details].

Outstanding principal: [amount and currency].

Please pay the outstanding principal by [specific date] using the verified bank details shown on the invoice. Please include [invoice number] as the payment reference.

This request concerns the outstanding principal only. The date above provides an additional opportunity to settle the overdue amount voluntarily; it does not replace the original payment due date.

If you have already paid, please send the payment date, amount and reference so that we can reconcile our records. If you dispute the amount, please explain the disputed items and provide supporting information by [date].

Please confirm receipt of this message. A copy of the invoice and a statement of the outstanding balance are attached.

Kind regards,

[name, role and creditor legal name]

[business contact details]

Remove the reference to a balance statement if you are not attaching one. If you have agreed a binding extension or instalment plan, do not automatically retain the sentence about the unchanged original due date. Adapt the letter to that agreement. For a disputed debt or planned court action, have a lawyer assess the specific letter and next steps.

How do you account for a partial payment?

Assume a domestic service invoice for PLN 6,150 gross, due on 30 October 2026. The customer has paid PLN 2,460, correctly allocated entirely to this invoice's principal. There are no credit notes, set-offs or other receipts. This is an illustrative calculation, not a Norman customer story.

Request PLN 3,690.00, rather than the full invoice total again. The Polish notation “3 690,00 zł” and English “PLN 3,690.00” represent the same amount. Keep one number format throughout the English letter and always state the currency.

If a transfer covers several invoices, resolve its allocation first. This example does not determine how to allocate receipts between interest, costs or several different debts. Record the balance-check date and recheck immediately before sending, particularly if you prepared the message the previous day.

How should you choose a deadline and delivery method?

Do not automatically copy “7 days” or “14 days”. Choose a reasonable, specific date for the circumstances and contract. For an invoice already due, distinguish extra time to settle voluntarily from a contractual extension. If no performance date is specified or follows from the obligation, Article 455 of the Polish Civil Code matters: a demand can have a different role from an ordinary overdue reminder.

Article 61 of that code focuses on the declaration reaching the recipient in a way that allows them to read it. A message in your Sent folder does not settle every delivery question. Check contractual notice requirements and the correct address. Retain the message, attachments and available confirmations; for postal delivery, retain posting and delivery evidence too.

There is no general rule requiring three reminders. A practising legal adviser explains demands, deadlines and delivery on the professional body's website in Polish. Further action depends on the case, not the number of emails your software has sent.

Should you add interest and recovery compensation?

Check the legal basis first. Articles 7 and 10 of Poland's commercial late-payment legislation set conditions for interest and recovery-cost compensation. Do not apply business-to-business provisions automatically to consumers.

Compensation can equal EUR 40, EUR 70 or EUR 100, depending on the monetary obligation: up to PLN 5,000 inclusive, above PLN 5,000 but below PLN 50,000, or at least PLN 50,000. Entitlement is linked to the specified right to interest, and the legislation defines the conversion into PLN. It is not an arbitrary fee for each reminder. Establish any interest or compensation separately before requesting it, rather than adding an unexplained charge to this template.

How can you organise reminders in Norman?

Norman provides payment reminders with editable Polish and English email templates. Automatic reminders require a paid plan and a customer email address. Review the invoice details, language, schedule and message before configuring them.

Keep receipts current through a bank connection or CSV import, then resolve discrepancies. Reminders stop when the invoice is marked paid or cancelled. If payment cannot be verified, the available confirmation or hold option helps avoid chasing a customer who has already paid.

Interest and compensation options add wording to the message; Norman does not automatically calculate or add those amounts. You must check the basis and contents of the request. Sending a reminder does not mean payment has been received.

For a Polish document, use the payment request generator. It produces a Polish PDF or DOCX for review and signature, including when used through the English interface. It does not send the letter. Adapt this guide's English wording separately. For the tax consequences of longer non-payment, see the separate guide to VAT bad debt relief in Poland.
