Tijana Starcevic gave a presentation on e-commerce. She defined e-commerce as selling products over the internet. While it may seem easy to start an online shop, it actually requires expertise and a lot of hard work. Some key steps to starting an e-commerce business include choosing a product and target market, setting up an online system and design, filling the site with products, launching the site, and ongoing marketing and optimization. Tijana's own company SixandSeven is an online lingerie shop that aims to provide a unique customer experience through quality products, design, and content focused on love and attention for customers.
