Clarification on Generating e-Invoices for Past Invoices No Retrospective e-Invoicing Allowed — You cannot generate e-invoices now for manual invoices issued before mandatory applicability. The system only accepts submissions for invoices issued after the threshold kicks in (e.g., post-August 2023 for ₹5 crore, or post-April 2025 for ₹10 crore turnover). 30-Day Rule Is Enforced by IRP — Even invoices issued after the mandatory date must be reported within 30 days. IRP will reject invoices submitted beyond this window. Non-Compliance Is Costly — Missed deadlines or errors in e-invoice generation can attract: A penalty of 100% of the GST or ₹10,000 per invoice. ₹25,000 fine for incorrect e-invoice details. Risk of goods detention if transported without valid e-invoice/IRN. Plan Ahead—Integrate Efficiently — To avoid rejections and penalties, invest in ERP or tool-based integration for seamless e-invoice generation and timely GSTR-1/e-way bill reconciliation. Bottom Line: No, you cannot generate e-invoices for past invoices issued before the mandate. And even if issued after, they must be submitted within 30 days—failures attract serious penalties. Staying proactive with systems and processes is essential for compliance.
