Will company A be notified by SMS or other information after the check of company A is transferred to company B?

Do you mean that company A writes a check to company B?

In that case, there will be no short message unless it is sent to you by the cashier of your company. When writing a check, it needs to be stamped with the bank reservation seal (financial seal and legal person seal) to take effect. If you have one of them, stamp it and you will know that the check has been written. .

What's more, when a check is issued, after the other party goes to the bank to cash the transfer, it will generally give a receipt back to your company's bank, and the cashier will get it when he goes to the bank, and there will also be relevant information on the bank statement.
