Can I generate e-invoices without using the portal?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Yes. You can generate e-invoices through a GST-approved ERP or billing software that is integrated with the e-invoice system. However, the invoice still gets registered and authenticated through <\/span><b>einvoice1.gst.gov.in<\/b><span style=\"font-weight: 400;\"> in the background.<\/span><\/p>\n<h3><b>2. Is API integration mandatory for e-invoicing?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">No. API integration is optional. It suits businesses with high invoice volumes, while smaller businesses can use the portal or offline utilities.<\/span><\/p>\n<h3><b>3. How long does it take to generate an IRN?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">IRN generation usually takes a few seconds once the invoice data passes validation checks.<\/span><\/p>\n<h3><b>4. What happens if IRN generation fails?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">The system rejects the invoice and shows an error message. You must correct the data and re-upload the invoice to generate the IRN.<\/span><\/p>\n<h3><b>5. Does e-invoice auto-populate in GSTR-1?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Yes.
