KYB: how to validate a company before closing a deal

Closing a deal with the wrong company — a shell supplier, a partner with serious liabilities or a firm tied to a problematic owner — can contaminate your entire operation. KYB exists so that this does not happen.

What is KYB

KYB stands for Know Your Business. It is the structured verification of a legal entity before and during a commercial relationship — the equivalent of KYC, but applied to companies. The goal is to confirm that the company truly exists, is in good standing and does not represent a legal or reputational risk.

What to verify in a company

• Tax ID (CNPJ): registration status, activity and time in operation;
• Ownership structure: who the partners and officers are;
• Ultimate beneficial owner (UBO): who actually controls the company;
• Tax status and lawsuits in the civil, labor and tax spheres;
• Adverse media and ties to high-risk individuals or companies.

Why this matters

Without KYB, the company is exposed to fraud, to shell companies used for money laundering and to the risk of being held jointly liable for an irregular partner. In compliance, third-party due diligence is not optional: it is what proves you acted diligently before engaging.

KYB and supplier due diligence

KYB is the foundation of supplier and partner due diligence. Instead of a one-off, manual check, it structures the assessment around objective criteria and keeps an audit trail — useful both when engaging and in a possible audit.

How to automate the validation

Validating company by company by hand is slow and incomplete. GUÉP KYB consolidates the tax ID, ownership structure, tax status, ultimate beneficial owner and adverse media into a single dossier, with a risk classification — so you can decide whom to do business with before signing.

Knowing the company across the table is what separates a safe partnership from a hidden liability.
