My best tool is my wife.
(Seriously)!
Phil is a qualified accountant (ACCA) and works as a company director for a glass company.
But she does my accounts for free. She helps me at exhibitions. She puts quotes together for large contracts and tenders. And she shouts at me for sitting on forums telling me I am wasting time and should be writing letters to big companies to stock our range.
What a superb piece of kit !
And she even posed for piccies on the website.
Awwww
