Best practices for managing inventory through an LLC in the United States from Switzerland include:
1. Creating a detailed inventory system that tracks current stock levels, purchases and sales. This system should also be able to provide insights into customer buying habits and trends so that you can accurately forecast future demand.
2. Utilizing automated re-ordering systems which trigger orders when inventory levels reach certain thresholds or when certain dates are reached in order to ensure product availability and minimize lost sales due to out of stock items.
3. Establishing relationships with suppliers located both domestically and internationally in order to ensure reliable sources of products at competitive prices as well as expedited shipping times if needed.
