I am no expert in this area but you can find out more information within this Facebook group which in turn leads you to all sorts of blogposts, webinars, twitter chats, EU documents and HMRC announcements which sometimes clarify, sometimes muddify. Many micro businesses will decide to cease trading as a result of these changes, at least in the short term. Some of the bigger e-selling platforms may take on the responsibility of dealing with VAT registration, invoicing, record keeping and payment obligations but that will come at a cost and prices will have to rise.
Fat Quarterly will stop trading. The good news is that we intend to resume trading as soon as all clarifications about the implementation of this law have been provided by HMRC and as soon as we can change and adapt all our systems to deal with all the new obligations. But we will be back!
