Accertify’s Stuart Mann on Reducing Fraud Without Sacrificing Revenue on the Merchant Sales Podcast

Accertify’s Stuart Mann recently joined James Shepherd on the Merchant Sales Podcast to discuss how fraud prevention has evolved from a back-office control function into a critical driver of revenue, customer experience, and long-term growth.

Throughout the conversation, Mann explains how the industry has shifted away from viewing fraud solely as a cost center. While merchants once focused primarily on blocking fraudulent transactions, today’s challenge is balancing risk management with maximizing approvals and minimizing friction for legitimate customers. As Stuart notes, many businesses still underestimate the hidden revenue loss associated with false positives, where good customers are incorrectly declined or subjected to unnecessary checkout friction.

The discussion also explores how modern fraud prevention increasingly depends on building context earlier in the customer journey. Rather than waiting until payment authorization to assess risk, merchants are now leveraging signals from account creation, login activity, device intelligence, and behavioral analytics to create a more complete picture of customer intent. By the time a transaction occurs, businesses can make more confident decisions based on a broader set of signals and historical context.

Another key theme in the conversation is the growing sophistication of fraud itself. Stuart explains how advances in AI and automation are enabling attackers to better mimic legitimate customer behavior, reducing the effectiveness of rigid, rules-based systems. In response, organizations are adopting more layered and adaptive strategies that combine machine learning, behavioral analytics, shared network intelligence, and continuous decisioning across the customer lifecycle.

The podcast also touches on emerging trends such as agentic commerce and the challenges associated with AI-driven purchasing behavior. While fully autonomous commerce remains in its early stages, Stuart notes that the underlying risk principles remain largely the same. Understanding identity, intent, and behavioral consistency will continue to be essential as merchants navigate new forms of digital interaction.
