By default, Odoo doesn't have a bill-wise aged partner balance report. With this module, we can have a pdf report of bill-wise and customer-wise(Odoo's default) aged partner balance reports.
A new field is added to the aged partner balance wizard to specify the report type. We can have two types of reports, bill-wise or customer-wise. Bill-wise option will output a bill-wise aged partner balance and customer-wise option will output a customer wise aged partner balance report.
Type of report will be mentioned in the report.
