The practical difference
GSTR-1 generally reports outward supplies, while GSTR-3B summarizes tax liability, input tax credit, and payment. Small businesses should prepare both from the same clean invoice and purchase data.
Prepare sales data first
Review invoice numbers, taxable values, GST rates, customer GSTINs, place of supply, debit notes, credit notes, export data where relevant, and any amendments before preparing outward supply reporting.
Review credit and tax payment
Before GSTR-3B, check purchase invoices, available input tax credit, ineligible credit, reverse charge exposure, tax paid in cash, and reconciliation against accounting records.
Create a monthly GST close
A fixed monthly GST close helps the business identify missing invoices, vendor mismatches, incorrect tax rates, and payment pressure before the filing due date arrives.
