Update on intermediary costs. The cheapest one found in the end was Avask. Pricing for registering is £250 (one time payment) £1200 annually to conduct IOSS filings. Yes, it is money for old rope but sometimes one has no choice. The lead time for getting an IOSS number via the Spanish portal is around 3 weeks so we've taken the plunge. It's eminently clear that none of the issues being discussed will be resolved by 1 July so if we want to continue to sell from our website and send DDP into the EU from 1 July we are going to have to go the intermediary route. I daresay that within a year, there will be a clarification or agreement and hopefully we can then file direct - but it's not guaranteed to happen soon. FYI, it seems that Ireland, Poland and Spain have a working portal, at least. Germany not and they are apparently difficult to communicate with anyway. I know first hand that the French goverment are the ultimate bureaucratic nightmare so avoid like the plague. Only problem with Avask is that they don't offer registration via Netherlands or Ireland, our preferred countries (as they speak English). This is, of course, only an issue if we eventually start filing direct. While you have an intermediary it shouldn't be a problem.
