i designed a sheet on ms excel, this breaks down in to , customer conhtact details, tiling area calculator, materials calculator. The tool has great flexability. Can apply a % discount for repeat customers, all calculations point to a central database so if certain material prices change then very easy to change my sheet. Its very easy to use if you have a laptop with windows 7. I will give you all a copy if you want. .....Anyway, i go with my laptop, a straight edge and an laser room size calculator thingy (better than a tape measure). Takes me about 15 mins to get all the details, i then have a chat with customer while showing them pics of my work on the pc. Then give them a price and politley ask for there business., All takes about 20 mins! I would say i get about 80% of jobs that i view. And this brings me on to another point!!, see the ones i loose out on, the customer most of the time has agreed the price and me to do the job then a week or 2 later change there mind so im starting taking small deposits again!!
