GST billing software for rooftop solar installers
Quote a rooftop system by its size in kW, add the PM Surya Ghar subsidy note, and turn the accepted quote into a GST invoice. Books bills a complete system as 70% equipment at 5% and 30% installation at 18%, so GSTR-1 and the HSN summary are right without a spreadsheet.
Made for rooftop solar epc, pm surya ghar vendors, solar dealers and installers.
