I was testing FBA-hero.com last month. Me and my family are located in Belgium. We've been selling on Amazon US so far and had success. Expanding to Europe sounded quite easy for us (as Europeans), but it was not. There were no services like TaxJar for VAT.
We've found FBA-hero.com via facebook. Christoph was very active in some FBA related groups. We had a chat via skype and he helped us to figure out how to start selling in Europe and how to manage the VAT. (Basically they are now managing the VAT) - once i month i send a report of my sellercentral and that's it.
Luckily i found them. I could definately reccomend them as a company. there might be some cheaper companies, but it's worth the money!
