Matt Brown's article, "B2B Payments Aren't Payments, They're Workflows," delves into the complex nature of B2B payments, framing them as intricate workflows rather than simple transactions. He highlights the multifaceted nature of billing, involving various teams like monetization, sales operations, and finance, each playing a critical role in the process. To streamline these operations, Lago has developed a system of role-based access with specific feature and action permissions, including roles for admins, account managers, and finance analysts, each tailored to their specific responsibilities. The admin role is designed for engineers who manage billing metrics and pricing, the account manager role empowers sales and customer success teams to handle customer billing interactions, and the finance & analyst role focuses on viewing and analyzing financial data. This system is designed to be fully composable, allowing for the creation of custom roles to match unique organizational workflows, emphasizing the need to view billing as a comprehensive workflow rather than a mere feature.
