Registering a business in the UK is far less intimidating than it sounds. Decide your structure, register with HMRC or Companies House, then set up the money side so you never mix personal and business spending.
Choose a name that is not already taken, check the trade mark register, and grab the matching domain and social handles before you print anything.
Open a dedicated business account. Even sole traders benefit — bookkeeping takes minutes instead of hours at year end.
Finally, set up simple invoicing, keep every receipt, and put aside a percentage of each payment for tax from day one.
