Don't know about in UK, but over here, when we send invoices to commercial customers, it looks like we're a fish and chip set up as we have to note on the invoice that all prices are net and not gross (inc VAT). It may give a less than prestigious appearance, but I've split my business to two different companies to stay below the VAT threshold.
It's only my opinion, but anyone who can run a business and not need to raise prices for 5 years must be a fantastic businessman. To have set prices 5 years ago that are still making enough profit today means you should be giving business seminars all over the UK.To be able to calculate profit margins and costs so far into the future means that you're in the wrong line of work. If I was as good as you are Richy, I'd work in the stock exchange mate. Well done.
Got any tips on how you've managed to do that?
