Net Order = COUNT DISTINCT(Order ID) WHERE Payment Status IS NOT "Voided" OR "Refunded"

The order equivalent to Net Revenue - the count of every unique order excluding those with the Payment Status "Voided" or "Returned".

Partially Returned orders are included in Net Orders.

If you're using Klar API to import order data into Klar, you can map the Payment statuses to be excluded from Net Orders by creating a Data Source Customization within the Klar API data source and select all relevant statuses, e.g. "unpaid" etc.
