I am a new EC and I am learning the hard way sometimes about how to deal with builders. Due to the cost of copper going up so much I am forced to ask for an increase in my contract price for the home models I am forecasted to do. Based on the amount of the increase in the cost of copper I have requested an increase in future jobs of 17% of the sale price for each model. We are anticipating completing between 350-500 homes for this certain builder in the next 12 months and have completed approx. 50 for them allready. I am coming to realize it's def. all business with these guys and there is always some strategy behind most eveything, not just being straight forward and honest about doing the work. If they were to refuse my request there would really be no point in carrying on with them because I would barely break even, but in turn the money in my receivables would be in there control and based on what I have seen in the past, if you leave a builder, whatever money they owed you was forgotten about or tied up for sooooo long it might as well have disappeared, any info would be great about dealing with these big builders or a different way to sale the increase???
