Was noticing that the work order analysis page utilizes hours billed to calculate the invoice margins. I feel that using hours clocked is a more accurate representation of profit margins for the management team. It isn't often accurate to cost out the technicians hours billed. When they are usually either more or less then the billed hours. So hours clocked would give a more exact value for the profit /loss on each individual invoice when using the analysis page for analytics..... In my opinion :)
