ERPNext - Pivot integrations - reports customization

Hello developers, We are looking for someone who's expert in ERPs customization to integrate Pivot table in all GRID VIEW reports. ERP name: ERPNext Language: I think it's called Python. You can read more about this by visiting their own web ([login to view URL]) Source: Open This ERP provide two types of reporting: 1. Default reports that are available from the service provider (Not we build). 2. Reports that we build in all modules called (Report builder) Both above are being provided to be exported to excel and all in GRID view which typically serve our need by integrating a pivot table tool within the ERP rather than exporting to excel to do the needed work from there. I'm attaching some sample reports that we need to have this Pivot tool integrated with (Which is not limited to these modules), however, we need to have it integrated with most possible grid view reports (Default and the one we build). The developer should grant us BUGS free across the entire system once this tool is integrated. We won't be paying him the full amount until we have tested everything before doing it perfectly.
