So simple to use – even my most technophobic clients can manage. Easy to install, quick to set up. Light years ahead of other shop plugins.
I’m so impressed I’ve recommended it to my website clients and am now using it for my own store along with four others for which I webmaster. Beautiful coding, excellent top-notch support, great documentation, fantastic how-to videos. Thank you so much Ecwid, you rock!
I’ve used Ecwid and I love the platform itself. Everything is so simplified it’s insane. I love how you have different options to choose shipping carriers, to be able to put in so many different variants. It’s a pretty open e-commerce gateway.
Einfach zu verwenden, erschwinglich (and a free option if starting off). Looks professional, many templates to select from. The App is my favorite feature as I can manage my store right from my phone. Highly recommended 👌👍
I like that Ecwid was easy to start and to use. Even for a person like me, without any technical background. Very well written help articles. And the support team is the best for my opinion.
For everything it has to offer, ECWID is incredibly easy to set up. Highly recommend! I did a lot of research and tried about 3 other competitors. Just try ECWID and you'll be online in no time.
