The system also supports issuing a draft invoice so users can verify information before the official issue.
To issue an e-invoice: 1. Tick the invoice that needs to be issued. 2. Select **Draft** to export a draft for checking, or select **Official Issue** to issue the invoice officially. 3. The system sends invoice data to the e-invoice provider and updates the invoice status. > **Example:** For invoice AR-0626-015 issued to customer "ABC Trading Co., Ltd." with Tax Identification Number (TIN) 0312345678 and amount 55,000,000 VND including 10% VAT, first issue a draft and verify customer name, TIN, invoice date, amount, and VAT. If all information is correct, select **Official Issue**. * **Draft invoice:** Does not show official invoice date or invoice number. Other information is the same as the final invoice and is used only for checking. * **Official invoice:** Receives the official invoice number/date from the provider and cannot be edited directly after successful issuance. > **Note:** An officially issued invoice cannot be modified directly. If information is incorrect, cancel the invoice or create an adjustment invoice according to the provider and tax authority rules.
