If your happy with the price of £25 then dont change it! I have priced 80 percent of my business £10 for fronts, i wont need to change those for anytime soon in the next 10 odd years and even then ill only need to put them up to £12 any new work gained ill i keep it as £10 front.
Let's hope none of your staff expect a pay rise over that period.
Honestly, that is seriously flawed advice.
Depends how you look at it and what you want from your business and life, if like me you want to earn maximum money for minimum effort and minimum time meaning spending more time with family and doing the things i want instead of slogging away working all the hours under the sun then how i do it is spot on.
Most would charge £5-6 fronts which by putting them up 50p a year or a pound every few years would take 10 years to get to £10 fronts so pricing an amount a customer is willing to pay via selling the service correct in the first place is the iceing on a cake for a sucsessful window cleaning business. I have in my eyes the ultimate business for myself that i know will give me an easy and stress free life.
As for if staff wanting a pay rise, i pay on percentage so there is no problem.
with a name like 8 weekly you have your own ways of doing things which are totally different to mine prob by charging 25-50 percent more a clean but still needing double the customers to have a full round which i can never realy understand but i would never tell you the way you do it is flawed as that is damn right rude!.
