You can view customer carts in the Order Settings > Shopping Carts tab.
There are 3 types of cart:
- Carts turned into orders. This is the best kind of cart as it means that the customer has got to the end of the purchasing process.
- Carts of identified customers. You need to look at this type of cart from the point of view of marketing to see how you can get the customer to come back to the purchase. Modules such as the abandoned cart reminder can be used.
- Carts of unidentified customers. This is the most complicated type as you have no information about the customer and there is nothing you can do.
