KYB vs KYC: What Australian Fintechs Need to Know

The core difference

KYC — Know Your Customer — is the process of verifying the identity of an individual. It typically involves checking a government-issued ID (passport, driver's licence), biometric verification, and address confirmation.

KYB — Know Your Business — is the process of verifying the identity and legitimacy of a business entity. In Australia, this means checking the ABN against the Australian Business Register to confirm the entity is registered, active, and structured as represented.

The distinction matters because a business is not an individual. You cannot verify a company with a passport check.

Why fintechs need both

Most Australian fintechs serving business customers need to conduct both KYB and KYC as part of their onboarding and compliance framework:

• KYB verifies the business entity — is the company legitimately registered? Is the ABN active? Is it structured as claimed?
• KYC verifies the individuals behind it — who are the directors, beneficial owners, or authorised signatories? Are they who they claim to be?

Operating without both creates significant gaps. KYB without KYC tells you the business is real but not who controls it. KYC without KYB tells you the person is real but not whether the business they represent actually exists.

KYB obligations for Australian fintechs

The specific KYB obligations for an Australian fintech depend on whether they are a reporting entity under the Anti-Money Laundering and Counter-Terrorism Financing Act 2006 (AML/CTF Act) and what products or services they provide.

Fintechs that are reporting entities must conduct customer due diligence (CDD) — which includes KYB for business customers — as part of their AML/CTF program.

Even for non-reporting entities, KYB is increasingly a commercial necessity. Lenders who do not verify borrower ABNs face higher default and fraud risk. Marketplaces that do not verify business sellers face reputational and legal exposure.

How KYB and KYC work together

In a well-designed compliance workflow, KYB and KYC work sequentially:

1. KYB first: Verify the business entity exists, is active, and is structured as represented
2. KYC second: Verify the identity of the individual representatives — directors, beneficial owners, signatories
3. Risk assessment: Combine the entity risk score (Fracture Score™) with individual risk signals to form an overall onboarding decision
4. Ongoing monitoring: Re-verify periodically — entity status can change after initial onboarding

KYB for different business structures in Australia

Not all business structures carry the same risk profile. Understanding the entity type is a key part of KYB:

• Sole Trader: Simplest structure. ABN is tied to the individual. Lower structural complexity but no corporate separation.
• Company (Pty Ltd): Separate legal entity. Verify both the ABN (ABR) and company registration (ASIC) for a complete picture.
• Trust: Complex structure. The trust ABN is separate from the trustee. Higher compliance risk — Osapher adds 20 points to the Fracture Score for trust structures.
• Partnership: Joint liability structure. Similar complexity to trusts. Also adds 20 points to the Fracture Score.
