根因分析

自2020年起，瑞士QR账单强制要求使用标准化的瑞士QR码（ISO 20022），包含27位IBAN、结构化参考号（ISR或QR参考号）和收款人信息；任何字段缺失或格式错误都会导致PostFinance或UBS等电子银行系统拒绝该账单。

English

Swiss QR bills (since 2020) mandate a standardized Swiss QR Code (ISO 20022) containing a 27-character IBAN, a structured reference number (ISR or QR-reference), and creditor information; omitting or misformatting any field causes the bill to be rejected by e-banking systems like PostFinance or UBS.

解决方案

  1. Use the official Swiss QR bill generator from SIX Group: download the 'Swiss QR Code' app or use the web tool at https://www.swiss-qr-bill.org/ to generate a compliant QR code with proper format and reference.
  2. Integrate a library like `qrbill` (Python) to generate bills programmatically: `pip install qrbill` and use `from qrbill import QRBill; bill = QRBill(account='CH4431999123000889012', creditor={'name': 'Jane Doe', 'pcode': '8000', 'city': 'Zurich'}, amount=1500.00, reference='123456789012345678901234567'); bill.as_svg('invoice.svg')`.
  3. Use accounting software with built-in QR bill support (e.g., Bexio, Klara, or Banana Accounting) that auto-generates compliant codes and validates fields before export.

无效尝试

常见但无效的做法:

  1. 80% 失败

    Swiss banks now require QR-IBAN for automated processing; regular IBANs on invoices may be processed manually or rejected, delaying payment.

  2. 90% 失败

    Each invoice must have a unique reference number (ISR or QR-reference); reusing a reference causes the bank to reject it as a duplicate.

  3. 85% 失败

    Many online tools produce non-compliant QR codes that lack mandatory fields (e.g., creditor address, currency); banks will reject them.
