What is the VATMOSS and how should I comply?

VATMOSS (Value added tax mini one stop shop) has been created by EU mainly for GAFA (Google, Amazon, Facebook, Apple) for fiscal aspects. From the 1 January 2015, businesses selling e-service to EU customers have to collect the VAT at the rate of the country and for the country. To comply you have to give your collection report to a country of EU.
