please inform me regarding this query.
what shall be the minimum billing amount for issue of a bill.
do I need to upload each and every invoice on the common portal in such form and manner as may be prescribed.
is there any provision as not requiring to upload on common portal the invoices if billing is done in cash and up to rs 50000.
