Frequently Asked Questions (FAQ)<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><strong>1. Does the adjustment\/replacement invoice require the buyer&#039;s signature? <\/strong><\/p>\n<p>According to current regulations, the buyer&#039;s digital signature is not required on the adjusted\/replaced electronic invoice. However, a written agreement between the two parties is necessary as a legal basis.<\/p>\n<p><strong>2. What should I do if I accidentally delete an incorrect invoice on the software?<\/strong><\/p>\n<p>\u201cDeleting\u201d an issued invoice is not in accordance with regulations. You need to perform the \u201cCancel\u201d, \u201cAdjust\u201d or \u201cReplace\u201d operations. If you make a mistake, contact the software provider for support and to ensure that the data is reported correctly to the tax authorities.<\/p>\n<p><strong>3. What to do if the invoice is incorrect but the tax declaration deadline is overdue?<\/strong><\/p>\n<p>You still proceed to issue the adjustment\/replacement invoice at the present time. After that, you must issue a supplementary VAT declaration for the tax period with the error and pay the tax difference (if any) and late payment interest (if any).<\/p>\n<p><strong>4. Can I create 1 adjustment invoice for multiple erroneous invoices?<\/strong><\/p>\n<p>No. Each adjustment\/replacement invoice is only issued for ONE erroneous invoice.<\/p>\n<h2 id=\"ket-luan\"><span class=\"ez-toc-section\" id=\"6_Ket_luan\"><\/span>6.
