Sir,

I am working in a water company like bisleri and makes supplies whole month. At the last of the month we generate invoices. The billing amount becomes more than 100000. Now we have to generate the e way bill. But e way bill can't generate because the supply of water is for whole month not only a single day. Now we don't have challan which can be use at the time of eway bill generation but we have a card which include tge daily supply data. So now how can we generate the e way bill without challan.
