Based on the provided information, PEP is seeking to replace its current customer billing and payment system due to a backlog in the billing and payment processes. The proposed system aims to interface with other new IT systems and updated business processes as needed. The key stakeholders involved are the Invoicing Department, Accounts Receivable Department, Sales Department, Ordering & Shipping Department, Marketing Department, and various executives. The current system uses an in-house developed Microsoft Access-based solution that is managed by the IT Department. The proposed system requires integration with other departments, secure data storage, automatic receipt generation upon payment recording, and reporting capabilities for company entities. The Preliminary Investigation Report will examine the problems/opportunities, identify benefits of a new system, and report on various aspects of feasibility.
