Your company has not signed a contract to activate the electronic invoice function.

The reason why the electronic acceptance bill cannot be signed for is that your company has not signed a contract to activate the electronic bill function. You must judge based on the error message of the system when the electronic bill is not successfully signed. It is recommended that you contact the customer service of the bank where your company has an account for detailed consultation. Because if you transfer the money order during non-bank working days, you need to make an agreement with the bank and let the bank check it.

Electronic acceptance uses electronic signatures and secure authentication mechanisms.
