Shift4Shop
Tocca una stella per valutare
Shift4Shop (formerly 3dcart) gives you a full ecommerce platform for free, but the catch is that you need to process payments through its parent company, Shift4. If that works for your business, you get product management, a shopping cart, and built-in promotional tools without paying a subscription.
It also includes SEO tools and an app marketplace so you can add functionality as you grow. The platform has been around long enough that it's stable, though it doesn't compete on cutting-edge features.
