  Everyday we learn something new. Can you please share reason why buyer needs a single invoice instead of 3 invoices? - GST Payer
  earlier he was saying bill once in a week. now he says one bill for one month - Ramani Rajagopal
  Just say a single bill from next month. It is better do not cancel the bill. GSTR-1 is yet confusing, how it will be done practically is difficult. You might have to issue debit note to party etc. It is better avoid it and from next month give a single invoice. - GST Payer
  thanks - Ramani Rajagopal
