There should be a recommendation/suggestion pop up option when you scan items.
An example would be you scan a phone it gives you the option for a case,screen protector, also the option for an upgrade fee.
Hello HH. We currently have something similar to what you are referring. After the initial sale of an item, any other item that is sold within the same transaction will become related. The next time you add an item to the dashboard, the related items will populate to the right of the customer section within the dashboard.
For example, if you sell an iPhone with an iPhone charger and an iPhone case and then you were to add the iPhone case to the dashboard, then the iPhone charger will be shown as a suggested item to add to the dashboard.
