境外電商導入台灣電子發票的注意事項與解決方案
Important Notes and Solutions for Overseas E-commerce Implementing E-Invoices in Taiwan
As Taiwan's e-invoice system continues to improve, more and more overseas e-commerce companies are beginning to implement e-invoices. However, during the process of issuing e-invoices, overseas e-commerce companies need to pay attention to some important points to ensure the accuracy and compliance of the invoices. Here are a few points to note when issuing e-invoices in Taiwan:
1. 發票號碼的序時序號
Sequential Invoice Numbers
發票號碼必須按照時間順序編號。由於ERP版系統會自動傳入發票號碼和日期，因此無法自動檢查發票號碼是否連續。境外電商需特別留意ERP發票號碼的給號順序，以避免發票號碼跳號或錯誤。
Invoice numbers must be assigned in chronological order. Since the invoice numbers and dates are input by the ERP system, it cannot automatically check whether the invoice numbers are continuous. Overseas e-commerce companies need to pay special attention to the sequential assignment of ERP invoice numbers to avoid skipped or incorrect invoice numbers.
2. 申報匯率與幣別
Declaration Exchange Rates and Currencies
境外電商在申報時需使用財政部公告的申報期間匯率進行計算。確保幣別與原幣金額的準確性，避免因匯率錯誤導致申報失敗。
Overseas e-commerce companies must use the exchange rate announced by the Ministry of Finance during the declaration period for calculations. Ensure the accuracy of the currency used and the original amount to avoid errors in the declaration.
3. C類發票開立與上傳時限
Issuance and Upload Deadlines for Category C Invoices
境外電商僅需開立C類發票，並需在以下時間內完成上傳：
Overseas e-commerce companies only need to issue Category C invoices and should complete the upload within the following time frames:
- 發票日期48小時內必須上傳至財政部確認。
- Invoices must be uploaded to the Ministry of Finance for confirmation within 48 hours of the invoice date.
- 發票開立日期24小時內需上傳至e首發票平台。
- Invoices must be uploaded to the e-Invoice platform within 24 hours of the issuance date.
e首發票會將發票轉檔為XML格式並排程上傳至財稅平台，超過時限可能會導致逾期。
The e-Invoice platform will convert the file to XML format and schedule it to be uploaded to the tax platform. Exceeding the time limit may result in delays.
4. 發票跳號處理
Handling of Skipped Invoice Numbers
如果發票號碼出現跳號，需在單月申報時找出所有空白號碼並進行申報，確保發票資料的完整性。
If there are skipped invoice numbers, all blank numbers must be identified and declared during the monthly declaration to ensure the completeness of the invoice data.
5. 境外專屬會員載具與EMAIL管理
Overseas Exclusive Member Carrier and Email Management
境外電商使用消費者的EMAIL作為專屬會員載具。如果提供空白或無效的EMAIL，消費者將無法接收或歸戶領取該發票，且系統會將其視為捐贈。此外，相同的EMAIL不可多次使用，否則國稅局將函文要求改善與解釋。
Overseas e-commerce companies use the consumer's email as the exclusive member carrier. If the invoice data provides a blank or invalid email, consumers will not be able to receive or retrieve the invoice, and the system will treat it as a donation. In addition, the same email cannot be used repeatedly. The use of the same email for multiple invoices will result in a letter from the National Taxation Bureau requesting improvements and explanations.
