Orders: Total number of orders which have been generated in the selected date range filter, sitebrand and source tool.
Order Value: The sum of the total value of your orders (including VAT) in the given date range, sitebrand and source tool. This excludes cancelled orders.
Est. Commission: The sum of estimated commission (excluding VAT) of orders which have been generated by your users in the given date range filter, sitebrand and source tool. It excludes cancelled orders.
Please note that the estimated commission you see here is different from the commission on your monthly invoice. The commission on your monthly invoice shows the commission which you receive for all orders which have been visited in that specific month. So, if a user books a ticket on May 30 for the Colosseum but actually visits the Colosseum on June 5, it means that in the Sales Overview, the commission is calculated for May, whereas on your invoice it will be included in your June invoice.
Refunded Commission: In case of cancelled orders, this is the sum of refunded commission (excluding VAT) for orders in the given date range filter, sitebrand, and source tool.
