New series in invoice means what?

For e.g. in Financial year your invoicing series was 1,2,3..
then in new financial year you will start new series from 1.4.19 which can be following:
01/19-20
02/19-20
03/19-20
....

Yes... This is mandatory.

In GST era we don't use same serial numbers in invoice. So, it's required different serials / sequence...

Ex :
in case we use serial in FY 17-18 as 01, 02, 03, 04... then we don't use the same 01,02,03,04.... in FY 18-19.
But, we can use any prefix or suffix serials as Your convenience... like

GST/01, GST/02, GST/03.... or
INV/01, INV/02, INV/03.... or any


But, Better to use FY in the series...

Yes, it is mandatory

Thanks all, according to my understanding if we have used 2017-18/01, 02, 03,
we go ahead with 2018-19/01, 02, 03
if am not wrong.

You are not wrong ya....


You are exactly Correct...
Continue the Same....

GOOD LUCK....
