GST E-Invoicing Compliance

India's GST e-invoicing system requires businesses to generate an Invoice Reference Number (IRN) through the government's Invoice Registration Portal (IRP) for every B2B invoice. InvoiceDX automates the entire flow — from ERP extraction to IRN generation to GSTR-1 filing.
