Hello,
Is it mandatory to maintain delivery challan no. in sequence when we send material for Job work process.
E.g. On 01/01/2019 Material is send for jobwork with delivery challan no. JOBWORK001
and on 10/01/2019 I send material for jobwork to another jobworker with delivery challan no. JOBWORK005.
I am not maintaining delivery challan no. in sequence.
Is it valid?
Please suggest as per GST law.
