Below are answers to frequently asked questions to help you understand and apply more effectively in invoice management:<\/span><\/p>\n<p><b>5.1 How to issue electronic invoices?<\/b><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">To issue electronic invoices, businesses need to use software approved by the General Department of Taxation. The basic process includes:<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Log in to the electronic invoice software system;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Create new invoice, enter buyer and goods\/services information;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Digital signature;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Send invoices via email or share a lookup link with buyers;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">At the same time, the software will connect and send data to the Tax Authority to issue a code (if it is in the form of a code).<\/span><\/li>\n<\/ul>\n<p><b>5.2 Can electronic invoices be issued to retail customers?<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Yes. When an individual customer does not request an invoice or does not provide sufficient information, the accountant still needs to issue an invoice and clearly state: <\/span><i><span style=\"font-weight: 400;\">\u201cThe buyer did not take the invoice\u201d<\/span><\/i><span style=\"font-weight: 400;\"> or <\/span><i><span style=\"font-weight: 400;\">\u201cBuyer did not provide name, address, tax identification number\u201d<\/span><\/i><span style=\"font-weight: 400;\"> in the buyer information section. This helps ensure regulatory compliance and makes it easier to control sales data.<\/span><\/p>\n<p><b>5.3 Is the red invoice a value added invoice?<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Yes. \u201cRed invoice\u201d was the previous popular name for <\/span><b>VAT invoice<\/b><span style=\"font-weight: 400;\"> printed directly on paper with a distinctive red color.
