Payment Insights & Benchmarks

Merchants in this MCC should prepare for a nuanced payment landscape, where acceptance rates and payment processes can present unique challenges compared to standard e-commerce. Understanding the common payment methods and associated pitfalls can help manage expectations around costs and customer experience.

Payment methods

Cards: widely accepted but may face higher decline rates due to perceived risk.

• E-wallets: gaining popularity for convenience, yet may have varying acceptance across platforms.
• ACH and direct bank transfers: often used for larger transactions, but can involve longer processing times.
• Financing options: increasingly offered to customers, affecting average transaction values and payment timing.

Authentication & security

3DS and other strong authentication measures are commonly utilized, affecting conversion rates.

• While these measures enhance security, they can also lead to cart abandonment if the process is cumbersome.
• Regular monitoring of transaction patterns and fraud alerts is critical for mitigating losses.

Benchmarks (indicative, not guaranteed)

MDR: typically higher than standard e-commerce, reflecting the specialized nature of the products.

• Rolling reserves: may be implemented and can vary substantially based on risk assessments.
• Settlement times: often extended, potentially taking 5-10 days or longer.
• Chargeback ratios: can be significant due to high-value transactions and customer disputes.
• Approval rates: generally lower than for standard retail, necessitating alternative strategies for transaction success.

Key metrics to monitor

Transaction approval rates segmented by method and customer demographics.

• Chargeback rates and the reasons behind disputes to identify trends.
• Average transaction value and its influence on payment preferences.
• Performance of financing options, including uptake and default rates.
• Customer feedback on payment processes to enhance user experience.

Risk & Compliance

Merchants classified under this MCC can encounter a variety of risks given the mixed nature of their products and varying customer bases. PSPs and acquirers pay extra attention to potential fraud, chargebacks, and compliance with AML/KYC regulations.

Chargebacks & fraud

Common fraud risks include friendly fraud where customers dispute legitimate transactions, often claiming they did not receive the product or service.

• Misrepresentation of merchandise quality or condition can lead to increased chargeback rates.
• Tooling like velocity checks, fraud detection systems, and enhanced transaction monitoring can help mitigate fraud risks.

AML/KYC expectations

Merchants must implement thorough customer identity verification processes, including checks for sanctions and politically exposed persons (PEPs).

• Source-of-funds verification may be required, especially for higher-ticket items or unusual purchasing patterns.
• Triggers for manual review may include large or unusually frequent transactions, discrepancies in identity documentation, and the use of alternative payment methods.

Operational red flags

Lack of clarity around ownership structure can raise concerns, especially in a market with potential undercurrents of fraud.

• Transactions from high-risk geographies or through unverified third-party resellers can alarm PSPs.
• Absence of clear return and warranty policies, making it harder for customers to resolve issues, can lead to disputes and chargebacks.
• Inconsistent or unclear product listings that fail to meet consumer protection standards may increase scrutiny from acquirers.
