Fraud Claim Management Chargebacks tend to understate fraud • Chargebacks can account for less than 50% of all fraudulent orders. • Many companies issue direct credits to customers in response to fraud claims. • When examining fraud loss, must capture losses due to both chargebacks and credit issuance.

Build a Model Model different scenarios • Vary chargeback rates, false positive rates, review rates • Model the effect these have on profit
Profit Optimisation….. …not necessarily chargeback elimination.
Summary • Determine the profit and loss drivers at all stages of your risk management pipeline. • Focusing on chargebacks alone is inadequate. • Determine the profit optimisation point for your business, and let this drive your acceptable chargeback rate.
