Background check of a Polish business partner

How to conduct a background check of a Polish business partner? Is it possible for a foreign company to check the information provided by the Polish company?

Many foreign companies want to be active on the Polish market or find a supplier from Poland. Before starting the business relationship, it is always a good idea to take the necessary steps to perform a background check of a Polish business partner.

Commercial register

The Polish Trade Register (Krajowy Rejestr Sądowy) is the best source of information about the Polish company. As in other countries, not all entrepreneurs are registered in the commercial register. It is possible to find here information about all companies except company constituted under civil law (spółka cywilna). The commercial register in Poland is accessible on-line. You do not have to pay for the HR statements, they are free of charge. The Polish Commercial Register is available on the website The information is unfortunately only available in Polish.

The following information can be found in a Commercial Register excerpt:

  • Information about shareholders
  • Names of the managing directors and authorized signatories

  • Information on insolvency proceedings and unsuccessful foreclosure
  • Indication of whether the company has filed annual financial statements to the court

Background check of one-man business

In Poland, the individual enterprises are not entered in the commercial register. All natural persons who run a business are registered in a Central Register and Information on Economic Activity (Centralna Ewidencja i Informacja o Działalności Gospodarczej – CEIDG). Here you can check the most important information about a Polish sole trader and company constituted under civil law. Access is possible at There you will find the most important information (address, tax number, REGON number). English version is available.

Background check of a Polish business partner

As far as taxes are concerned, we can ask for a clearance certificate from a future partner (zaświadczenie o niezaleganiu z podatkami). This would make it possible to check whether the Polish company has no tax debts. From June 2018, a register will be kept in Poland, with the taxpayers registered with arrears. To check your future or current business partner please contact our office. We’ll conduct the background check in your name.

Legal analysis

If we find out that the Polish company exists and has a valid VAT ID number, this does not automatically mean that the foreign company should sign a contract or place an order. It is first recommended to legally review the contract template used by a Polish counterparty.

Above all, the general terms and conditions of the Polish business partner are to be examined. The most important points that a foreign company should consider:

  • choice of law (of course, Polish law is usually proposed)
  • application of the UN Sales Convention (CISG)
  • jurisdiction (the Polish companies naturally prefer the place of jurisdiction in Poland)
  • limitation of liability
  • payment conditions
  • out of court settlement of disputes
