I'm currently in the process of starting to write a business plan for a 'company' idea i've been toying with for a while now. My question to all those out there in cyberland is if i am classed as self-employed how do i go about getting items at trade prices? When you register with HMRC as self-employed do they give you a unique number (like a VAT number and/or a Limited Company) to show to companies you are entitled to things at trade prices?
