EDD EU VAT is a necessary plugin, it collects the required data for EU laws compliance, allows reverse-charge, adds the legal mentions in invoices, and generates exports that make it a lot easier - not to say even "possible" to me, as a self-employed - to fill VAT returns each quarter, and EC Sales returns each month.
We were looking for a way to handle EU VAT on our multivendor platform that we run from Finland. The plugin was a perfect solution for us.
