Business-to-business transfer can be returned if it is wrong. According to the "How to Return the Wrong Accounts of Public Companies in the Original Way" published by Pro, it can be known that after the wrong accounts are reversed, public companies need to keep their own transfer records and contact the company's finance department to return the funds. If the other party refuses to return the funds, the transferor needs to contact the bank in time and ask the other party to return the funds through legal means. Only when the name and account number of the other company match correctly at the same time can the company-to-company transfer be successful. If there is no match, the funds will be returned to the transferor's account. Relevant regulations on public account transfer: authenticate both parties to the transaction to prevent payment fraud. We can use digital signatures and digital certificates to authenticate the identities of all parties involved in online commerce to prevent payment fraud, authenticate the validity of the identities of all parties involved in online commerce, and issue digital certificates to all parties involved through certification institutions or registration institutions to confirm the legitimacy of their identities.
