What you're legally owed
When a B2B invoice goes unpaid in Poland, the governing statute is Ustawa o przeciwdziałaniu nadmiernym opóźnieniom w transakcjach handlowych (transposing EU Directive 2011/7). It gives freelancers and small suppliers automatic rights to statutory interest and a flat compensation fee on every overdue invoice — no contract clause required.
- Statutory interest
- NBP reference rate + 10 percentage points (B2B, if creditor is an SME) or + 8 points
- ~15.75% per year in early 2026 for SME creditors
- Flat compensation fee
- €40, €70, or €100 (sliding scale based on invoice size)
- rekompensata za koszty odzyskiwania należności
- Default payment term
- 30 days from delivery/service; max 60 days B2B
- Public sector max
- 30 days
These amounts accrue automatically from the day after the invoice due date. You do not need a contract clause to invoke them — the statute creates the right directly. A contract can set a higher rate, but not a lower one.
How to enforce it in Poland
The primary enforcement path for freelancers in Poland is the Elektroniczne postępowanie upominawcze (EPU).
An entirely electronic order-for-payment procedure. File online at the e-sąd portal, fee ~1.25% of the claim with a minimum of PLN 30. Uncontested cases reach enforceable order in 2–6 weeks.
Small claims limit: PLN 20,000 (postępowanie uproszczone).

What to do this week
- Add a late-fee clause citing Ustawa o transakcjach handlowych to your contract template. Use the freelance contract template as a starting point.
- Add one line to your invoice footer: “Late payments accrue interest under Ustawa o transakcjach handlowych at NBP reference rate + 10 percentage points (B2B, if creditor is an SME) or + 8 points, plus a €40, €70, or €100 (sliding scale based on invoice size) rekompensata za koszty odzyskiwania należności.”
- When an invoice goes overdue, use the free late-fee calculator to get the exact amount owed, then send a formal demand letter citing the statute. The demand letter guide walks through exactly what to include and what to leave out.
- If the letter's deadline passes, run the escalation playbook — or file directly via the Elektroniczne postępowanie upominawcze (EPU), which is designed to be used without a lawyer for undisputed debts.
One thing most freelancers don't know
Poland uses a tiered EU-style flat fee (€40/€70/€100 depending on invoice size) and applies the higher 10-point interest premium when the creditor is a small business — a rare pro-SME carve-out.
This guide is a plain-language summary of Ustawa o transakcjach handlowych as it applies to freelancers and small suppliers. It is not legal advice. For disputes over larger amounts, or anything with a contested fact pattern, consult a lawyer admitted in Poland.
