i have an a4 sheet of paper which has the customers name address and phone number, time and date of when the quote is to be done, this then gose into my work folder, which gose everywhere with me when i work, on this a4 sheet i write all the measurements any prep work that needs doing, ect. when ive worked out a price i then write it out there and then on my 2 sheet carbon copy headed quote paper they get a copy and i keep a copy which is then stapled to the a4 sheet and this then becomes there job reference.
i never rush a quote and always spend plenty of time with them explaining every aspect of the job, and i try and get them booked in there and then, which at the end of the day is what its all about...
however larger or more complicated jobs i will have a think about and pop back to see them, i much prefer the face to face contact..
