If you run a brick and mortar business, you should consider creating an online store as well. With an online store, you can sell your products to customers around the world. Your online store is open 24 hours and 7 days a week. Your customers will find it more convenient to shop at your online store.
Since you already have an inventory, all you need to do is list your products in the online catalog. You will need an e-commerce content management system (CMS) to list your inventory on the website. The e-commerce CMS is integrated with a shopping cart.
