Nice one Harry.
I go with the Mike Halliday school on turnover. It means jack schhhh.
It's profit that counts, but even that's not strictly true. My next door neighbours are 2 young professionals earning loadsa dosh. Their house is identical to mine, but their mortgage is considerably more than £1k per month. Mine's just gone up to £111.03p. So I don't need anywhere near the income to maintain a given lifestyle. What I'm trying to say is we all have different circumstances and different needs. Our turnover, net profit and domestic outgoings are all different. Any figures that anyone produces for turnover or net profit would have little relevance to most others here.
Safe and happy accounting:)
