I have run a Shopify drop-shipping online store in the past, which included, creating product listings( uploading pictures, writing title and description), setting up legal pages and information pages, setting up marketing email and SMS flows, fulfilling and processing orders, keeping track of inventory and stock and reporting/replenishing when it got used up interacting with customers and solving their problems and concerns, keeping in contact with the supplier to make sure there is enough stock on their part and shipping is well.
