On the Pro Summary, it shows the "sold hours." (and says 'billed hours' when hovering over the question mark). It does not reflect actual "billed hours", calculated by dividing labor revenue by the labor rate. Instead, it counts the hours from each invoice and divides them by the total number of invoices. The reason this is not as useful as basing it on labor income is that for the menu-priced items, like oil changes, we sell them at .7, but collect a reduced dollar value. As we try to improve our "billed hours" per invoice, this makes a difference. We are striving for a .4 improvement, when in reality we need a .6 improvement when we do proper math with labor revenue. It would be nice to have this calculated to reflect actual "billed Hours", for simple reference.
