Is GST billing software mandatory?
Yes, for GST-registered businesses, using compliant billing software is essential. E-invoicing is mandatory for businesses with turnover above ₹5 crore. The software must generate invoices with proper GSTIN, HSN codes, and tax breakdowns.
What is e-invoice in GST?
E-invoice is an electronic invoice that is authenticated by the GST Network (GSTN). The invoice is uploaded to the Invoice Registration Portal (IRP) and receives a unique Invoice Reference Number (IRN). This is mandatory for B2B transactions above the threshold.
