Sales and Inventory System Thesis Chapter 5- Concept of Operation : Proposed Solution

Throughout the study the researchers came up to propose a solution that will minimize the difficulties of RV Empire Incorporated in their manual sales and inventory system. The proposed solution is to make the system computerized, a system that can be easily manage, will be a user-friendly to the user so that through this solution the delayed of transactions will be minimized.
