i dont get how you can charge more for 2 monthly, as if a wc said to me it i will do once a month for £10 but 1 every 2 months for £15, he is getting more money for a little bit more work, but i am paying more a clean, so would feel as if i was getting conned
There's nothing to get because there isn't any rules
thats why you get people on forums saying you can't do that
they have set their own rules and think they apply to you as well
you don't need to get or understand other peoples business
just make sure you get your own business
