I do have scheduled dates for cleans and I like it this way....each customer knows when I am due next and if I turn up and access if not available as agreed...the customer is billed for the full price..
Had a lady the other day fail to do this, she then rang and complained saying that it wsas not fair, she was then refered to the terms and conditions that we both agreed to...in the end she saw our side of it..i.e we allocate time to clean her house on a particular day and if we cannot clean she is still billed.
I am aware that some people do not like to schedule work, I do and find that it suits me.
No access...no problem, you're still billed.
Cheers
Dave.
