KYB Program Design for Payment Processors

KYB stands for Know Your Business. In banking and payments, it is the process of verifying that a business customer or merchant is legitimate, understanding its ownership and control structure, and assessing the financial crime risk it presents. KYB commonly includes entity verification, beneficial ownership review, sanctions screening, risk classification, and ongoing review. It supports sound merchant onboarding and bank-partner confidence.

Payment processors onboard businesses that receive, send, or facilitate payments, making them vulnerable to fraud, money laundering, sanctions exposure, and prohibited activity. A structured KYB program helps verify merchants before activation, apply enhanced diligence to higher-risk relationships, document decisions, and establish a reliable basis for ongoing monitoring. It is also central to meeting the expectations of sponsor banks and regulatory stakeholders.

A KYB review generally collects the legal business name, formation details, tax or registration information, physical address, nature of business, expected payment activity, ownership details, and information on individuals with control. Depending on risk, the review may also include licenses, websites, processing history, source-of-funds information, adverse media screening, and supporting documents that substantiate the business’s legitimacy.

KYC, or Know Your Customer, verifies an individual’s identity and evaluates the risk of a customer relationship. KYB applies similar principles to legal entities. It verifies the business itself, identifies beneficial owners and control persons, examines the business model and expected activity, and determines the appropriate level of due diligence. Payment processors commonly need both: KYB for merchants and KYC for relevant individuals.

KYB refresh frequency should be risk-based rather than one-size-fits-all. Higher-risk merchants, businesses with complex ownership, or merchants with material changes in activity generally require more frequent reviews. Lower-risk relationships may follow longer review cycles. A strong program also triggers event-driven refreshes when ownership changes, sanctions concerns, unusual activity, negative news, or significant profile changes are identified.

Yes. An effective KYB program should reflect your specific merchant categories, payment products, geographic exposure, transaction patterns, distribution model, risk appetite, and sponsor-bank requirements. Pillars FinCrime Advisory helps define risk tiers, evidence requirements, escalation paths, and approval standards that are proportionate to your actual exposure. This avoids both under-controlled onboarding and unnecessarily burdensome reviews for lower-risk merchants.

KYB establishes the expected profile of a merchant, including its business model, ownership, anticipated volumes, and payment activity. AML monitoring then uses that profile to identify behavior that may be inconsistent with expectations or indicate potential financial crime. When KYB and monitoring are aligned, investigators have stronger context for alerts, better documentation for decisions, and a clearer basis for escalation or suspicious activity reporting.

A complete KYB policy should define scope, governance, risk assessment methodology, required customer information, beneficial ownership standards, verification procedures, sanctions and adverse media screening, risk tiers, enhanced due diligence, approval authority, record retention, ongoing monitoring, periodic reviews, and escalation requirements. Procedures should then explain how teams perform each control consistently, document decisions, manage exceptions, and report program results to leadership.
