When I do my few insides I charge, 1.5 x outside.
I only have 3 jobs, that I do insides, done regular, no nets or ornament craziness.
I use to do more insides but got fed up as even if asked customers didn't remove nets or clutter off sills.
Had quite a few regular in/out monthlies over the years but always end up dumping, customer starts off Great but by 6+ cleans goes pear shaped😖
They always move the goal posts.
Schedule, agreed times, cancel, skip cleans etc.
The biggest problem for me is the rigidity of it all, as it's an appointment, only do now if it's the first job of the day, otherwise I don't want to know!
Don't want to organise my day around a customer.
I think there is a saying:" There's no grief, like you give yourself!"
I know it shouldn't, but it bothers me when a customer wants insides done asap but they have the insides done every 2+ years.
These are the ones I charge 2x outside but really try my best to steer them into investing towards a karcher window vac 😁
Did think of having insides done on bad weather days only.
e.g. Have a list of customers and phoning through it when weather bad.
But find customers only want done same time as outsides 😐
Also the only one that's flexible is me 😁
