Is checking a business partner free?

Yes. A NIP check in the Ministry of Finance's VAT register (White List) is free, without an account or registration.

What will I see after entering the NIP?

The entity's identification details, VAT status and bank accounts listed in the register as at the selected date. The register does not confirm the business's solvency or replace a full business partner check.

Why check a business partner before a transaction?

Payment to an account outside the White List may have tax consequences, while the partner's status and history help assess non-payment risk. It is better to check before issuing an invoice.
