While you may be able to find a startup agency or small Shopify development team to create your entire Shopify store for $500, you may not get everything that you need. More established and professional eCommerce development companies can charge anywhere from $5,000 to $30,000 for a custom-designed Shopify website. These agencies offer entire project management teams that can not only create an excellent eCommerce store but offer extra functionality of a Shopify site.
