Payment Insights & Benchmarks

Merchants in the Lumber and Building Materials Stores MCC should anticipate unique payment challenges compared to standard e-commerce. Payment acceptance often hinges on the mix of methods utilized, customer demographics, and the risk appetite of payment service providers.

Payment methods

Cards: widely accepted, but certain high-ticket items may face tougher scrutiny and approval rates.

• E-wallets: gaining traction, especially for one-time purchases, although not as common for large transactions.
• A2A transfers: effective for larger orders, though not all customers may be familiar with this method.
• Checks: still used, predominantly for larger business transactions, but can delay the payment process.

Authentication & security

Strong customer authentication (3DS) is commonly employed for online transactions to combat fraud.

• While these measures enhance security, they can lead to increased cart abandonment if not optimized.
• Merchants should be aware of fraud trends specific to high-value transactions, requiring additional vigilance.

Benchmarks (indicative, not guaranteed)

MDR: generally higher than standard e-commerce due to the nature of the products sold.

• Rolling reserves: may be implemented, particularly for high-order amounts, often above standard levels.
• Settlement cycles: may take longer (typically 5-10 days), especially for larger transactions.
• Chargeback ratios: could be above average due to the complexity of customer disputes in construction-related purchases.
• Approval rates: lower than traditional retail, particularly on credit card transactions for higher value sales.

Key metrics to monitor

Authorization rates segmented by product type and payment method.

• Chargeback reasons categorized by product disputes or dissatisfaction.
• Trends in payment method utilization over time to gauge customer preferences.
• Large transaction fall-off rates to identify potential acceptance issues.

Risk & Compliance

Merchants under this MCC face specific risks due to the nature of products sold and the customer segments they serve. PSPs and acquirers are vigilant about compliance, as these businesses can be exposed to fraudulent transactions and chargeback issues.

Chargebacks & fraud

Common issues include friendly fraud, where customers claim they didn’t authorize a purchase for materials they received.

• Chargebacks can also arise from disputes over product quality or service delays.
• Mitigation tools include transaction monitoring, robust return policies, and leveraging device fingerprinting to identify suspicious transactions.

AML/KYC expectations

Strong customer identity verification (IDV) is crucial, especially for large transactions typical in this sector.

• Sanctions and PEP checks must be a standard part of the onboarding process.
• Manual review should be triggered by unusually large purchases or frequent changes in payment methods.

Operational red flags

Lack of transparency regarding the ownership of the business can raise concerns; merchants should disclose all beneficial ownership.

• Selling to unfamiliar or high-risk geographies can draw scrutiny, especially if combined with unusual purchasing patterns.
• Absence of clear product return and warranty policies can alarm PSPs, as this can contribute to increased chargeback rates.
• Missing or unclear disclaimers regarding service timelines and delivery methods may also signal operational weaknesses.
