Logistics and Operations Application

I am looking to have a Logistics and Operations Application developed. The application needs to have a specific set of features, including Inventory Management, Order Tracking, and Route Optimization. Additionally, it needs to be able to integrate with any existing applications or systems, if any. Lastly, the completion time should be within a span of 1 month, 3 months, or more than 3 months, depending on the project timeline.
