Merchant underwriting is the comprehensive due diligence process conducted by an acquiring bank, Payment Facilitator (PayFac), or Independent Sales Organization (ISO) to evaluate the financial stability, legitimacy, and risk level of a business applying for payment processing services.
The Purpose of Merchant Underwriting
Before granting a merchant account, the underwriter must answer three core questions:
-
Is this a real, legally registered business with verifiable owners?
-
Does the business model comply with card network rules and government AML laws?
-
Does the business have the financial stability to cover potential chargebacks and refunds?
Key Factors Assessed
Underwriters analyze a wide array of data, including processing history, credit reports, Merchant Category Codes (MCC), corporate structures (UBOs), and the merchant's physical and digital footprint.
