There are 3 types or reporting metrics that SellUp provides.
These are: Upsells Created, Upsells Views and Upsells Adds.
This is the amount of upsells you have created within the app.
This is the amount of times your upsells have been viewed in the past 30 days.
This is the amount of times an upsell has been added to a customers cart.
Can I see successful purchases?
There is no direct metric to see orders containing your upsells. This is because SellUp would require access to your customer data. SellUp is a data friendly app and does not have any access to any customer data.
That being said, if your upsells are being added to cart then you have most likely created offerings that make sense to the customer.
At the time of writing, individual metrics for each upsell are being added shortly to the app. This will allow you to identify upsells which are working and those which are not.
