Customer GSTN cancelled.. to be treated as B2C?

Supplies made to un-registered persons should be shown as B2C.

If in future if he revoked that is if he get his GSTIN back then it will obviously B2B.

Agree

For my client out of 950 invoices 10 customers GSTN been cancelled... we have a large master info for customer..

now we have to create new ledger as b2c for cancelled customers...
in future if he revokes again I have to bill as B2B..

THIS IS AGAIN BECOMING A RECONCILIATION PROCESS ON SALES TOO

if the customer asks to amend the April bill... we have to amend ?
