Enviro, you may want to specify a price in the general setup (services or materials) for things for which you charge set price by the unit. (ie /hr, /1000 sq ft, /cu yd, Linear ft, etc.

All of my Services and Materials have set prices/unit for simplicity; this streamlines estimating. My fixed prices all originate from estimated units used. If I happen to underestimate the units, then I try to adjust later with incremental price increases for future services. With services or materials with per unit prices, all you need to do is add the item to an invoice/sched job/extimate then enter the quantity for that customer. The only thing Gopher lacks in this regard is the abilitly to have sub catagories. I will be posting a wish list item for this.Once you settle on a fixed price for a customer, its then as AZTLANLC states, easier to just specify the fixed price for each specific customer (until the next adjustment)...Tom
