How we picked the 3 top rated products

We chose the high-performing solutions on this list based on verified user ratings on our site. Depending on available data, qualifying products either had to be among the most user-reviewed or the most searched-for products in the shopping cart software category. They also needed to have sufficient reviews about third-party integrations, have a minimum user rating of 3 out of 5 for that feature, and show evidence of U.S. market presence.
