Payment Insights & Benchmarks

Merchants in the Plumbing and Heating Equipment and Supplies sector should anticipate higher payment friction relative to standard e-commerce, influenced by factors such as payment method mix, fraud prevention measures, and the risk appetite of payment service providers (PSPs).

Payment methods

Cards: commonly used, but may face higher scrutiny, affecting approval rates.

• E-wallets: an increasing choice for their convenience in transactions and potential for lower fees.
• Bank transfers: popular for larger purchases, though can have slower processing times.
• Financing options: often offered at point of sale but can deter customers if perceived as complex.

Authentication & security

Strong customer authentication (SCA) measures like 3D Secure may be prevalent, impacting user experience.

• While these measures enhance security, they can also lead to transaction declines if not well-integrated.
• Continuous fraud monitoring is essential to identify and mitigate risks associated with high-value purchases.

Benchmarks (indicative, not guaranteed)

MDR: generally higher than standard e-commerce due to increased fraud risk.

• Rolling reserves: may be required by PSPs, typically higher for higher ticket sku categories.
• Settlement time: may take longer, often exceeding 5 days.
• Chargeback ratios: can be elevated compared to other sectors, warranting attention.
• Approval rates: usually lower for card transactions, particularly for high-risk profiles.

Key metrics to monitor

Authorization rates segmented by payment method and customer profile.

• Chargeback and return rates by product category to identify trends.
• Average transaction size and its relationship with payment method.
• Payment processing times by provider to optimize cash flow management.

Risk & Compliance

Merchants under this MCC are closely scrutinized due to elevated financial and reputational risks. PSPs and acquirers typically apply stricter controls, expecting merchants to proactively address fraud, chargebacks, and AML/KYC compliance.

Chargebacks & fraud

Common fraudulent activities include the use of stolen payment information, fake transactions for high-value items, and chargebacks due to product not being as described.

• Customers may dispute transactions claiming they did not receive goods or services, leading to increased chargeback rates.
• Mitigation tools include device fingerprinting, behavioral analytics, and order verification protocols to ensure legitimate customers.

AML/KYC expectations

Strong customer identity verification (IDV) is essential, with comprehensive checks against sanctions lists and politically exposed persons (PEP).

• Source-of-funds verification is highly recommended for transactions above a certain threshold or when unusual patterns are detected.
• Manual review triggers include large or frequent purchases, inconsistent shipping and billing addresses, or high-risk geographical locations.

Operational red flags

Transparency gaps such as unclear ownership or lack of information about suppliers can raise concerns for PSPs and acquirers.

• High volumes of transactions from newly established accounts or rapid transaction frequency may attract scrutiny.
• Absence of clear refund or return policies can be a major red flag indicating potential fraud risks.
• Poor customer service response times or unresolved customer complaints may signal operational weaknesses.
