If you need support from Yola please contact us via email@example.com or make use of our live chat service! We are working on a new approach to community-based support and during this transition period we are not adding any new threads to this forum. Many thanks to everyone who has participated over the years and we look forward to unveiling a new peer-to-peer support system soon!
Shopify and Yola are both website building systems.
Yola uses the Ecwid widget or app to integrate the Yola Online shopping cart. Shopify is it's own system. You could build a Shopify site with its own domain and a parallel Yola site with another domain and then bring the Shopify site into the Yola site. This method though is clumsy as you are already provided with all sitebuilding resources with your Shopify subscription.
It would be to your and your customers benefit to stay with one or the other.
