Opening Balance without entry

Good day
One of my clients was using Excel sheets for accounting entries then he shifted to a local accounting software and he transferred the balances of all the accounts both Assets and liabilities without making opening balance entry from the excel to the new system , now he wants to shift to ERPNext, my question is it possible to transfer the accounts without making an opening balance entry ?
Waiting your kind advise.

It is possible but not advisable as your balance sheet would not show correct numbers.

why? and how to do so?


You can see heare what I am looking for:

In ERPNext, there is no functionality to add opening balance while creating an account. You have to update opening balance via Journal Entry.

ok, how I can add this feature to ERPNext?
Could you guide me please?
