How do I hide my price line from my customer?
When you are creating lines with your customer looking at the screen, you may want to hide your price line. Click the Pricing Options button at the bottom of the Line Items tab, and select Hide Dealer Price. You can also do this for the List Price.
If you want those price lines to always be hidden, you can do that in your User Options. Go to the Tools menu, and select Options. On the Line Items tab, check the Hide Dealer and List Price checkboxes.
