Rquest to exempt eway bills

The concept of E-way & E-invoice is different.
E-way is applicable only when value of Consignment is > 50k & being transported by Motorised Conveyance.
Whereas E-invoice need be done If the Taxpayer Aggregate Turnover in preceding Fy exceeds 20 Crore.

So it is not mandatory the where E-invoice has been generated for any supply , need the E-way bill also.

Yes the purpose of both concept is track & minimise Fake invoice & malpractice in trade.
