How to maintain a bank account after opening an account

How to maintain a bank account after opening an account?
1. The minimum amount of the bank should be maintained regularly and there should be some collection and remittance transactions every month, otherwise the bank will freeze the bank account after one year. At that time, the directors need to submit materials or go to the bank to handle the operation of account recovery.
2. If there is any change in the company, such as the change of director/shareholder/business address/change of business, the company secretary should be notified to update the company's information in the registry, and then submit relevant documents to the bank.
3. Do not do business with suppliers and customers in sensitive countries.
4. All invoices and supplier contracts shall be kept so that the bank can provide the required documents in time.
5. There shall be no remittance or collection from a third party, and all payees and remitters must be consistent with the relevant documents.
6. The bank contact person should pay attention to the bank call. If he misses the bank call to inquire about the bank transaction, it will indirectly affect the bank's decision on the whereabouts of the account.
