-# ADR for Payment Boundary
-
-## Context
-The payment processing system is pivotal for the business operations, therefore a well-defined boundary is necessary to manage dependencies, isolate services, and ensure the resilience of the application.
-
-## Decision
-We will implement a microservices architecture for payment processing, with the following boundaries: 1. Payment Service, 2. Notification Service, 3. Reporting Service. These services will communicate through well-defined APIs and will be independently deployable. 
-
-## Alternatives
-1. Monolithic architecture - rejected due to tight coupling and scalability issues.
-2. Service-oriented architecture - rejected due to complexity in service integrations compared to microservices.
-
-## Consequences
-This decision allows for better scalability and maintainability of the payment processing system but will introduce challenges in inter-service communication and data consistency management.
