The plugin tracks all the orders originated by the European Union countries with the total number of orders and the total amount of taxes exempted for each one in detail.
You can access the IOSS report in YITH -> EU VAT -> Reports.
You can filter reports by current year, current month, last month, last 3 months, last 6 months, last year, or custom date ranges and show them by order or by country.
From this section of the plugin, you can also export the reports into a CSV file by clicking on Export CSV.
