with the talk about Xmas coming up I think its more important to start thinking about Jan & Feb
So...... prime every customers for cleaning at this time, tell them the truth, things tend to slow down a bit in Jan & Feb so you offer a number of special offers at this time, Tailor each special offer to them, if they have a leather suite tell them you do a special deal on leather cleaning, if you only clean the downstairs tell you you are doing 3 bedrooms for the price of 2.
Tell them you'll give them a ring in Jan & Feb to see if there is anything they need doing ( I say tell them not ask them )
if you wait until Jan, look at your diary and see its empty, it because you didn't do the ground work now
"By failing to prepare, you are preparing to fail." Benjamin Franklin
