ERP for bottle water business

I am the head of an existing bottle water business and looking a cloud-based ERP system to manage our operation. We require a system that can support up to 5 users. The purpose of the project is to improve the efficiency of our business processes thereby allowing us to provide better services to our customers. The resulting ERP should be able to integrate with any existing systems, provide centralized data access, and capture and analyze data to generate reports. It should also effectively manage our inventory, orders, customers and other business needs. We are looking for a high quality and cost effective solution that can be customized to meet our needs.
