This rollout is so bad...I've spent hours going back and forth with customer service about this.  To get access to the new invoices, they ask me to create a new account, backup all of my data and move it over.  What a joke.  I actually created a new account, which has the new invoices.  Luckily I didn't migrate all of my data over because after a couple days it reverted back to the old style of estimate without a way to revert it back to the new one.  Such a joke...
