Because the sales contract can be your "loan reason", but it cannot be your "loan certificate".

Usually, the proof of enterprise loan can be: business license (it needs to reach a certain number of years and meet the standard of public water and public tax payment), factory building, land or equipment (it can be used as mortgage loan or credit loan, and it usually needs capital verification by authoritative departments).

For example, if you use factory equipment as a "voucher" to borrow money from a bank, the bank will ask you what the reason is after a series of audits and capital verification. At this time, you can say that signing a contract takes up funds (enterprise capital turnover) and you need to issue your sales contract to the bank for verification. Because if your loan is used for buying a house, trading stocks or investing, the bank will not approve it. You should understand this time.

Of course, different banks in different regions have different requirements for loan qualifications, but as far as I know, a simple sales contract can never be used as a "voucher" for loans.
