Wow price really seems to be an area of huge debte in our industry.
My view for what its worth is this
Price really is'nt such a big issue for alot of clients the right people will pay you well for good service. -you only have to ask

The biggest problem i found when I upped my prices was convincing myself that I deserved to earn more.
I started my business for a reason - i want a very good standard of living and charging £80/£90 for a sofa and £50 for a lounge was'nt giving me the income I wanted.
I mayed the decision that a business should pay what I want it to pay me or I'd do something else.
Lets face it Its a dirty horrible job. I for one am not prepared to clean the crap out of everyone elses carpets for peanuts.
I also dont think theres such a big issue with north and south - I genuinley know people who charge the same as me and they live in the north.
I charge .79 per sq ft for cleaning and 1.11 for cleani and protect, i wouldnt do it for any less.
Its not unusal for people to go with us after having a qoute for half our price. People pay for service, Quote to low and alot of people will ask whats wrong with it!!!!
I would recommend the fasttrack course if your prepared to make changes - its no good going in with the attidude of trying to slate it before you try it. Personally I have implemented the basics of what it teaches and they work very well. I dont like all the strategies but then hey if you only use a handful of ideas it will pay.
So most importantly all I'd say to everyone is up your prices and all us cleaners will work less and earn more

just provide good honest service with it!
