Payment Insights & Benchmarks

Merchants in the car and truck dealers' sector should anticipate unique payment dynamics, including fluctuating approval rates and potential for higher chargeback ratios. Understanding these factors is crucial for effective cash flow management and operational resilience.

Payment methods

Cards: widely accepted but can face scrutiny based on transaction size and customer behavior, leading to variable approval rates.

• E-wallets: growing in popularity for down payments and holiday purchases; however, limitations on transaction limits may apply.
• Financing options: often utilized for larger purchases, requiring integration with lending partners and additional compliance.
• Anchored loans: available through certain PSPs, but may involve extensive vetting processes.

Authentication & security

Strong Customer Authentication (SCA) measures are typically required to mitigate fraud risk, particularly for larger transactions.

• 3DS (3D Secure) is common but can lead to increased friction, potentially affecting approval rates.
• Continuous fraud monitoring is essential, especially for high-ticket sales, to detect unusual activity patterns.

Benchmarks (indicative, not guaranteed)

MDR: generally higher than the average e-commerce due to increased risk factors.

• Rolling reserves: may be requested, particularly from high-risk PSPs, often in the range of 10-20%.
• Settlement cycles: typically longer, often exceeding 7 days, affecting cash flow.
• Chargeback ratios: likely to be above retail norms, necessitating efficient dispute management.
• Approval rates: generally lower than retail, particularly for high-value transactions, with approval varying significantly between methods.

Key metrics to monitor

Risk & Compliance

Merchants operating under MCC 5521 face significant scrutiny regarding financial and fraud-related risks. Payment service providers (PSPs) and acquirers impose rigorous compliance measures, making it essential for these merchants to proactively manage chargebacks, fraud, and adhere to AML/KYC standards.

Chargebacks & fraud

Frequent chargebacks stemming from customer disputes over the quality or discrepancies in the vehicles sold (common with used cars).

• Notable instances of friendly fraud where buyers dispute transactions claiming they did not authorize the purchase.
• Fraud schemes may include the use of stolen identities to buy cars or parts, and return fraud for parts that are not new or were falsely advertised.
• Mitigation tools include transaction monitoring systems, vehicle history checks, and identity verification techniques such as two-factor authentication.

AML/KYC expectations

Strong emphasis on customer identity verification (IDV), including comprehensive checks against sanctions lists and politically exposed persons (PEP).

• Source-of-funds checks required for high-value transactions, such as vehicle purchases, especially those above typical market values.
• Manual review triggers can involve large cash payments, unusual transaction patterns, or discrepancies in provided identification and ownership documentation.

Operational red flags

Lack of transparency regarding vehicle provenance and dealer information, potentially leading to compliance concerns.

• Unexplained or atypical traffic sources, particularly from foreign or restricted areas, which could indicate potential fraudulent activity.
• No explicit customer policies regarding returns, warranties, or service guarantees, raising concerns about customer dissatisfaction.
• Insufficient documentation related to essential due diligence practices or missing records of prior sales.

Explanation:

While the definitions across networks are largely similar, nuanced differences in terminology can affect how certain services are categorized. For example, licensing requirements and the conditions under which dealerships operate can differ. Networks may also have varying standards for the documentation needed during the onboarding process, and factors like regional restrictions and fraud monitoring can influence acceptance decisions. Common reasons for rejection include lack of proper licensing, insufficient documentation, and higher risk associated with geographic locations.

Alternative MCC Codes

Merchants often confuse this MCC with other categories. The table below shows which codes are related, why they are confused, and what risks misclassification brings.

Rule of thumb for merchants:

If your primary business activity involves selling used cars or related leasing, ensure you use MCC 5521. Misclassifying under a different code can lead to processing delays, chargebacks, and even account termination. Always select the code that reflects your main business function.

Merchants operating under the MCC 5521 must navigate a specialized landscape that includes vehicle sales, service, and parts leasing. Adhering to best practices is essential not only for reducing risk but also for enhancing customer trust and ensuring payment acceptance.

Classification & transparency

Fraud & chargeback reduction

implement 3DS or step-up authentication especially for high-value transactions or unusual purchasing patterns

Payment acceptance optimization

offer multiple payment methods, including credit cards, financing options, and digital wallets, to broaden acceptance

• consider routing payments based on geographical regions or transaction types while regularly testing provider performance
• utilize separate MIDs for major service categories (e.g., sales, repairs) to better manage payment processing requirements

Operational discipline

monitor KPIs such as transaction volume, approval rates, chargeback ratios, and customer lifetime value actively

• conduct regular compliance audits of payment processing practices, updating policies as necessary
• designate a specific team or individual responsible for managing disputes and ensure responses are prompt and recorded

Payouts & liquidity
