If you trade overseas you need to be prepared for changes in the way you do business as the UK's Brexit arrangements will come into force on 1st January 2020.
"We understand these are challenging times, but it is important your business is ready for these new rules. At the time of writing, talks are ongoing about our future trading arrangements with Europe. Trading rules will not change or go away, and the steps that you need to take to prepare, are needed in any scenario before you can trade from 1 January." [gov.uk]
Contact us if you need support or to talk through your Brexit challenges. There are also government webinars which we strongly recommend you consider attending - these are available to register at via the government's website.
