To enable the Hide Pricing feature go to (1) Setup – Company – (2) Users.
For each User that you would like to hide pricing from select the User Name and scroll down to Permissions. Uncheck the Hide Pricing checkbox.
When Hide Pricing is enabled the User will not see Labor Rates, Service Fees, Item or Part Pricing. See below for an example of a Work Order viewed by a User that has Hide Pricing enable.
