9. Life of an SMB: Pre & Post GSTN
All my Invoices needs to be GST compliant & uploaded
to GST network every month by 10th of the successive
month
Follow-up for payment from my client is more painful (If
I don’t upload my client will not pay as they can’t claim
credit)
Need to reconcile purchases as mismatches will lead to
loss of tax credit and hence it is critical to track
purchases too
Sending the transactions offline (excel) may not be
viable as the returns are broken into 3 stages with
tighter deadline & penalty
My invoices and expenses are tracked in my
system of record (typically excel) and later given
to my CA
Follow-up for payment from my client is painful
(I can send invoice through any medium and
claim input credit later)
Don’t have time to record my vendor bills so
don’t know my total expenses (my CA will do
that)
Tax payment & filing is a backend process.
Multiple sources of data is submitted to the CA
who prepares returns

10. GSTN Compliant Invoice - Sample
GSTIN of the
supplier is required
Place of Supply is critical to
determine tax rates applicable
(CGST/SCGST) or IGST
Every item (Good or Service) need to have
either CGST/SGST or IGST
Every item needs to have a HSN
(Good) or SAC (Service) assigned
by GST
