Risk & Compliance

Merchants under the Air Conditioning and Refrigeration Repair Shops MCC are subject to specific risk and compliance considerations due to the nature of their services and customer interactions. PSPs and acquirers implement stringent measures to safeguard against fraud and manage chargeback risks effectively.

Chargebacks & fraud

Common types of fraud include service disputes where customers claim work was not performed or was done improperly, as well as friendly fraud.

• Abusive customers may attempt to claim refunds for legitimate services rendered, leading to increased chargeback incidences.
• Fraud mitigation tools include transaction monitoring systems, customer feedback reviews, and clear documentation of service agreements.

AML/KYC expectations

Robust customer identity verification (IDV), including government-issued ID and address verification, is expected to reduce risks associated with unverified clients.

• Businesses must perform sanctions checks and monitor for suspicious transactions, particularly large cash payments or patterns inconsistent with typical repair service transactions.
• Triggers for manual review include frequent high-value transactions, use of different payment methods from the same customer, and irregular business behavior.

Operational red flags

Lack of transparency around service customer claims or unclear business ownership structures may raise concerns for PSPs.

• Numerous chargebacks or refunds without adequate explanations can indicate operational weaknesses.

• Failure to maintain clear service terms and conditions regarding prices and refund policies can also alert PSPs to potential issues.
