I've designed lots of websites using mockups and directing a Web Builder but with the emergence of platforms like Squarespace and Shopify, I am now able to create websites for clients in their entirety while also keeping costs low.
Squarespace is a friendly platform that is great for more simple websites whereas Shopify is incredible for ecommerce sites. The Paper People is a greeting card company (belonging to myself and my husband) with over 100 different cards being sold through the Shopify platform. I have set this site up in its entirety integrating numerous apps, payments platforms, google analytics, facebook pixels, klaviyo forms etc. A site of this size needs to be maintained and content needs to be edited fairly frequently to keep google happy.
