Extra work is extra pay...period
Leaving them a bill won't work because they won't pay it
If a client leaves a list for extras and a check for the normal amount, fine.
Do the work you agreed on and leave them a note saying that you will be glad to handle this list of extras on the next visit and the cost is $$$
You have just let them know nicely that you do not work for free, and what the
cost for the additional services is.
When/if you return they have not left the additional monies just do your normal job and forget it.
People will try anything once,its your job to politely keep the relationship on
the right track, and you must do that the FIRST TIME this happens.
If you let them get away with it once you will set yourself up for more of the same.
There are many tricks that they use...
One of my favorites: "You don't need to vacuum and dust the second bedroom today, but clean the oven for me!"
Or While your here could you clean the windows in the living room I have company coming for the weekend.
Its a whole lot easier to vacuum and dust a bedroom than clean the oven, not to mention the HUGE time difference.
So, what are you going to say when this happens.I know what I did.
How about trying to work double time doing the house and now she has you feeling a sense of urgency
to clean her windows remember her friends are coming for a visit.What do you say?
How do you respond to this slick con artist?
