RE: Freelance work - getting paid
No the inland revenue might, but its not likely.
Just call the company something like "the web co".
Example: We had some building work done at work and my mate done it, cause he is employed by someone else and was doing it 'on the side' he couldn't raise an invoice, we wouldn't pay without one, as it was going threw our books, so he literly gave us an invoice from "bob the builders", its an invoice, we paid it, he got his money, we put it threw the books. Nothing dodgy on our part, he was taking the risk, but a minimal one at that.
