Hi and welcome to the grumble!
The example prices that come with the POS software are not meant to work "out of the box" for every market. Prices that work in NYC won't work in Alabama. They are just a guide to get you started, and in many cases were probably set several years ago as part of the installer program.
When we installed our POS, we found the default prices to be set very high; as if in the Manhattan market.
We shopped our market, spoke with other shops we were on good terms with, and decided on default markups for mouldings, labor, and mats that are slightly higher than the local market.
We erased all the glass prices and calculated our own, based on actual cost from our vendor and a floating markup.
That was almost 3 years ago, and i think we've adjusted the prices about 10 times since. It's a constantly changing matrix that requires some thought and research of your market - and of your workflow/time management.
Which one did you get?
Congratulations!
Mike
