What's the name of the loan company doing backstage work?

It's called a backstage search warrant. After signing the sales bill, the backstage warrant officer will match the loan channel (bank) according to some information of the lender. Because each bank's loan policy is different, it is necessary to find the most suitable and easy-to-make bank, dock with the bank, wait for the bank's review after submitting the information, follow up the loan progress reviewed by the bank, and assist the sales to inform the lender to collect the money after the bank relaxes.
