Debtors balance report

We expect this kind of debtors balance report with party wise and invoice wise report in ERPNext.

Thanks for reporting this! Fortunately whoever wants to can implement and contribute that https://docs.erpnext.com/docs/user/manual/en/customize-erpnext/articles/making-custom-reports

Start with the general ledger report. This will give you a good starting point for what you need.
