If I update a rate card used on a project, what happens to the time cards?

Invoiced time cards will be unaffected, however, when saving the project an Inquiry form will appear telling how many time cards could be revalued using the new rates and what the net effect to contract and billing adjusted revenue will be. You will have the option to click yes to revalue the cards, click no to leave them as is or click cancel to exit without changes.
