BIG InfoMonitor: the Polish credit bureau entry, explained

Debt Recovery Poland · guide for foreign creditors · updated July 2026

Ask anyone who recovers debts in Poland what makes debtors pay, and you will hear one answer more than any other: the BIG entry. This guide explains what it is, why it works, and how a foreign creditor can use it.

What is a BIG?

BIG stands for Biuro Informacji Gospodarczej — a credit information bureau operating under a dedicated Polish statute. BIG InfoMonitor is one of the main bureaus. Its database is checked routinely by banks, leasing companies, factoring providers, telecoms and larger trading partners before they grant financing or sign contracts.

Why it changes debtor behaviour

Conditions to list a business debt

  1. The debt arises from a business relationship and totals at least 500 PLN (about €120);
  2. it is at least 30 days overdue;
  3. the debtor received a proper demand with a listing warning (wezwanie z ostrzeżeniem) at least one month before the entry, sent by registered mail or delivered personally.

The formalities matter — an entry made without the correct demand can be challenged. This is one of the reasons the demand stage should be run from Poland, by an operator who does it daily.

How a foreign creditor uses it

A foreign company cannot practically sign its own bureau agreement and run Polish-law demand formalities from abroad. In our service the entire path — the compliant demand letter, the statutory waiting period, the entry, and its removal after payment — is handled for you in Poland. You track the case in English; the debtor experiences the consequences in Polish.

The BIG entry works best as part of a sequence: demand letter → public registry listing → BIG entry → (if needed) e-court. Each step raises the cost of not paying. See the full path in How to recover a debt from a company in Poland.
