What will be requested: ・These mandates regulate invoices between enterprises within the EU and do not directly apply to Taiwanese exporters ・However, buyers' systems will shift to accept only structured invoices—what actually happens is "your PDF requires manual re-entry; can you provide a format we can directly import?"
What to do now: 1. Ask your buyers: How do their accounts payable systems currently handle your invoices? Manual entry or already requesting structured formats? 2. Understand hybrid PDF (Factur-X / ZUGFeRD): One PDF file with an embedded EN 16931-compliant XML. When opened by a person, it looks like a standard PDF; buyers' systems can directly parse the data inside. No pre-coordination needed between parties. 3. Check whether your invoice data is sufficiently structured: tax identification numbers for both buyer and seller, quantity units and unit prices for line items, tax classification—these are mandatory separate fields in EN 16931 and cannot be mixed into a single text string.
