Hi NewlandPC
You can enter opening balances after that conversion month if required.
The key thing to note would that the system will track them as the opening balance for that period. For example, in your case, if you entered the balances as of Feb 2023 but you ran a report for Aug 2022 it will say that the balances would be Feb 2023's balance, not $0.00. There is no harm in that and it's just a reporting situation but it is something to take note.
And, yes, you probably want to enter other previous invoices and bills outstanding as historical sales/purchases.,
