lee, it is a tricky one knowing what is the right frequency.
I decided to do monthly had the odd few want bi-monthly, tried i was always late got pi55ed of with people moaning it's 10 weeks not 8 weeks.
So just do monthly.
What i say to new custy's is i come on calander month (same date every month, but can be a few days late)
In reality it takes me 5 weeks to get round i very rarely get a not today, if i show in 4 weeks i would get custy's moaning it can't be that time again! if i show up in 6 weeks get some saying, i nearly did windows myself
Do what you feel is right, i wouldn't make to many options, you'l just make your life difficult.
imo, i went into window cleaning because it is a simple repeat business.
I want to keep it that way.
As you get busier lee you will not be able to be so obliging because you wont have time.
I think most people are happy to find a good relialble w/c, i have had a few say they were going to leave it as i wouldn't do bi-monthly, then a couple of months later came back to me.
I have wrestled with the frequency thing myself but now i look at it like this.
The bus stop round the corner runs to a specific time table.
The people that want their service don't argue and get on board.
The ones that want it their way end up walking.
