We need to develop a customized ERP system. This will functionally traverse multiple areas of operations for our company including Customer Relationship management, invoicing, project/task management for production, Point of Sale, and a customer self-service web portal website. The emphasis will be to enable employees to create sales orders and invoices with standard services that require manual parameter inputs that to properly calculate the cost of the goods. Also, we need to integrate with our site: download orders and update the order status from the ERP system. The system should support offline exchange between the two offices. Each office should work independently.
