Enterprise car rental question

I have personally use enterprise a few times but today my girlfriend will be using them to rent a car. I am finding mix answers, so they need to bring a copy of a bill or paystub? Or can she just go in and rent a car? She has money and a credit card and valid DL. She canceled her insurance last month cause she got rid of her car. But has to go to Austin for two days. All her bills are online. Will they accept them if they’re online? I only used enterprise for military never as a civilian so idk what the difference is beside we don’t need to show proof of residency. I am currently in a different country so I can’t help much
