Shopify — Build Your Own Online Store
Ready to grow beyond marketplaces? Shopify helps entrepreneurs create branded online stores, manage products, accept payments, and build direct relationships with customers.
Many sellers start on Etsy or eBay, then expand to their own storefront to own the brand, the customer list, and the buying experience. Shopify is the platform entrepreneurs use to run that next stage without hiring a development team.
