The IRP validates the invoice data, registers it, generates the IRN (a unique 64-character hash), and returns the IRN and a digitally signed QR code. Zoho Books stores both against the invoice record and adds them to the printed invoice PDF. The entire process takes a few seconds and is invisible to the user unless there is a validation error.<\/p>\n<\/div>\n<div class=\"gt-section\">\n<h2>e-Invoice Validation and Errors<\/h2>\n<p>The IRP validates e-invoices against strict criteria: GSTIN format, HSN or SAC code format, invoice number uniqueness, and mandatory field completeness. Common rejection reasons include an incorrect GSTIN, a missing or invalid HSN code, a duplicate invoice number, or an invoice date more than a specified number of days in the past (currently three days for larger businesses). Zoho Books displays the IRP error message alongside the invoice so you can correct and resubmit.<\/p>\n<\/div>\n<div class=\"gt-section\">\n<h2>e-Invoice Cancellation<\/h2>\n<p>An e-invoice can be cancelled within 24 hours of IRN generation by requesting cancellation through the IRP. Zoho Books provides a Cancel e-Invoice button within the 24-hour window. After 24 hours, the IRN cannot be cancelled on the IRP; you must raise a credit note instead. Zoho Books does not allow an e-invoice to be edited after IRN generation: all changes must go through a credit note and a new invoice, maintaining a clean audit trail.<\/p>\n<\/div>\n<div class=\"gt-example-box\"><strong>Industry:<\/strong> Manufacturing \u2014 A Pune auto-parts manufacturer generates 150 e-invoices per day in Zoho Books. The IRN generation is automatic. On average, two to three invoices per day fail IRP validation due to customer GSTIN data issues. The accounts team corrects the GSTIN in the customer record and resubmits within the hour, ensuring all invoices are e-invoice compliant before goods leave the warehouse.<\/div>\n<div class=\"gt-related-pills\"><a href=\"https:\/\/aaxonix.com\/resources\/glossary\/gst-zoho-books\/\" class=\"gt-related-pill sp-content-link\">GST<\/a><a href=\"https:\/\/aaxonix.com\/resources\/glossary\/gstr-1-zoho-books\/\" class=\"gt-related-pill sp-content-link\">GSTR-1<\/a><a href=\"https:\/\/aaxonix.com\/resources\/glossary\/e-way-bill-zoho-books\/\" class=\"gt-related-pill sp-content-link\">e-Way Bill<\/a><a href=\"https:\/\/aaxonix.com\/resources\/glossary\/gstin-zoho-books\/\" class=\"gt-related-pill sp-content-link\">GSTIN<\/a><\/div>\n<div class=\"gt-faq-item\"><strong>What is e-Invoice (IRN) in Zoho Books?<\/strong><\/p>\n<p>An e-Invoice in Zoho Books is a GST invoice registered with the Government of India&#8217;s IRP, which generates a unique IRN and QR code.
