You will be able to view an individual customer's transaction history directly from their loyalty profile via the Loyalzoo software.
Simply head to store.loyalzoo.com, type the customer's name in the search box and then select the customer's profile.
To view the customer's history, tap the underlined "xx days since last purchase" button.
This will allow you to view the customer's full transaction history, see example below.
To view earlier transactions, just scroll down. To go back to the customer's profile, tap the X button in the top right of the history screen.
