This is standard in every world. Corporate credit cards are usually reserved for senior executives or people who travel/entertain a lot (e.g. sales reps). Cash advances aren't a thing outside of small companies.
Google is the exception here, IMO. Every other employer I have had has generally required the employee to front the cash for expenses, and used something like Expensify to get reimbursed. There are some exceptions, such as hotels or airfare, which I've booked through corporate booking systems; these only let you see "approved" flights/hotels, and once booked, is charged direct to the company.
It may prevent the employee from holding the bag if the company goes bust. But some "corporate cards" are issued by banks in a way that makes the cardholder jointly liable.
The exception tends to be law and accounting firms, which issue cards to their employees for business use. The employee "pays" up front using the cards, but the card is connected to the employer's expensing system and the funds are deposited to the employee's account the payday following his submission of the expense report.
You would rack up your tab, submit your expense report and then they would issue you a check with which it was your responsibility to pay the tab.
One guy racked up like $50,000 on his card, got the check and then quit and never paid off the card...
Dont know what ever happened to him.
