+# Orders Report
+
+The Orders Report provides insight about your store's orders.
+
+By default, orders with non-excluded statuses are listed by order date descending. Excluded statuses can be edited on the [Settings page](https://github.com/woocommerce/woocommerce-admin/blob/master/docs/woocommerce.com/analytics-settings.md#excluded-statuses)
+
+Refunded orders cannot be excluded from the orders report. Refunded orders have two rows in the report: one for the date of the original order and one for the date of refund.

+### Advanced Filters
+
+The advanced filters allow adding multiple filters to the report. These filters can be applied in two ways:
+
+- All - Orders must match all filters to be included in the report
+- Any - Orders must match one or more filters to be included in the report
+
