I have read that, we can upload sales or supply of service invoices in GSTR 1 by json format as many times we can.
but I have a quary that I should include the invoices which are already uploaded in the same month, OR every time we should upload only fresh/new invoices only...?

as per me you should upload only fresh, even if you try to upload the old data then there should be error of INVOICE number already exist on database.
