When presenting multiple tiers of pricing the default labels are "Value," "Standard," and "Premium." However, these labels are customizable.
To change those labels:
Go to My Account.
Click on Work Orders.
Then click Work Order Settings.
Change the labels to what you want. Note: Character limit on labels is 20.
This changes the labels for your task list, manage book and calculations tabs on the web. On the app it will update on your price book, work order, option boards and their respective PDF's.
