The commercial acceptance bill is about to expire, and the bearer fills out the entrusted collection voucher and submits it to the account opening bank to entrust the collection of the draft. The account holder's bank will send the entrusted receipt and draft to the payer's bank. If the payer bank has sufficient funds for the payer's account to pay, the money will be paid from the payer's account and transferred to the account holder's bank through the interbank transaction.
