We use Oracle Commerce Cloud for the e-commerce portion of our website. We're currently split between using OCC for the e-commerce portion and SiteCore for the Marketing and product information focus. It's far more robust and user-friendly than our previous e-commerce solution, with the ability to easily address our mobile optimization issues we've been experiencing, as well as easily running A/B tests to optimize conversion rates.
The backend is also far, far more easily utilized than our previous home grown solution, which required a significant amount of IT and programming help to add or modify any products. With Oracle Commerce Cloud, marketing can easily add, adjust, and categorize products without IT involvement.
