Universal Containers uses the Salesforce Platform to track customer payments and any late payments.

Universal Containers uses the Salesforce Platform to track customer payments and any late payments. This is accomplished with an architecture that includes Marketing Cloud, Service Cloud, and an integration to the back-office billing system via MuleSoft. Invoices and payments are mastered in the billing system and exposed to Salesforce via MuleSoft. Notifications about customer payments are orchestrated out of Salesforce and emails are sent via Marketing Cloud. The late payment invoice data is required for service representatives to be able to reference within Salesforce.

What should the Solution Architect recommend when determining the role of each system for a use case of sending payment reminders?
