KYB Vetter lets your AI check a Polish counterparty before you invoice, pay or sign.
Give it a NIP (tax id) and it answers from the official registers: whether the company is an active VAT payer on the Ministry of Finance white list, which bank accounts are registered to it, what the National Court Register (KRS) says about its legal form, capital and representatives, and whether the names across registers agree. Give it a bank account number and it tells you whether that account is assigned to the NIP, the check Polish law expects before paying a B2B invoice above 15 000 PLN.
