NMRICH explains how its commerce report counts orders
Commerce reporting filters by order creation date and groups payment and refund-related orders by currency and current status.

The report supports filtering by date, member, currency and status. The summary and detailed rows use the same filters, so staff can trace a result back to the matching orders.
Amounts are stored and aggregated in minor units, with each currency shown separately. The report reflects current order status. Use the relevant transaction and settlement records for reconciliation.
