Merchant Accounts: Architecture and Risks | IB PlayBook #20
📌 Description
In this episode, we examine merchant accounts as a key element of the payment architecture, through which all the consequences of the previous stages flow. We show how merchant profiles are configured, what decisions are made at the processing level, and why configuration errors can go undetected for years.
We discuss the connections between the merchant, payment provider, bank, and anti-fraud logic, how responsibility is allocated, and where systemic risks arise. Here, we understand why problems rarely look like "one bad transaction" and how architectural decisions directly impact losses and business sustainability.
This episode prepares for the final part of the course—an analysis of large platforms and how scale changes protection strategies.

▶️ What's Next
In the next episode, we'll look at a large e-commerce platform in practice and analyze how scale, distributed teams, and complex architecture change the approach to anti-fraud and payment security. This is the logical conclusion of the entire course.
We recommend watching the course sequentially—each episode builds on the previous one and completes the overall picture.
