Danny,
We always closely follow the brief, it is in our interest to as we absolutely detest any customer cancellations that are unnecessary, we of course refund ones that are deemed proper such as customer losing job, too low a price(Very rare) Customers not lasting the first 2 cleans, Wrong type of job, e.t.c.
We work not for the odd window cleaner, but as many as 5 different ones in a week, and we make sure with each one that we go through criterias, pricing and so on for a good 15-20 mins before we start work so that all the staff are clear in what they are looking for, wether it be WFP or trad.
Canvassing in general has really tightened up in the past year as many people thrown out of work try their hand at it, so getting the criteria right has never been more important to us as it is right now.
Paul
