如何在我的 Sign.Plus 发票中添加增值税、税号或公司信息

If you need a Sign.Plus invoice that includes your company name, Tax ID/VAT number, or billing address (for tax filing or accounting), here's how.

如何在购买时添加账单信息

When upgrading or purchasing a Sign.Plus plan, you can enter your billing details before completing payment.

1. On the checkout page, locate the Billing Address section.
2. Fill in your billing information:
   • Country – Select from the drop-down list.
   • Address – Enter your street address. Use the optional Address Line 2 for suite, floor, etc.
   • City, State/Province, and ZIP/Postal Code – Provide your location details as shown on your payment method.
3. If you're making a business purchase, check I'm purchasing as a business and complete:
   • Company Name (e.g., "Good Mood, Lda")
   • Tax ID (e.g., "PT504208209")
4. Review your information, then complete the purchase.

Your billing address will be saved for future invoices and receipts.

如何更新您的账单信息

如果您需要更新现有的账单信息：

1. Log in to Sign.Plus.
2. Go to Settings → Plan & Billing.
3. In the Billing Details section, update the necessary fields (address, postal code, Tax ID, company name, etc.).
4. Click Confirm to save your changes.

Future invoices will reflect the updated information.

我可以获取 W-9 或 W-8 表格吗？

我们提供 W-8 表格（因为我们的公司总部位于瑞士，而非美国）。请参阅如何获取 Alohi 的 W-9 表格？。

我们不提供 W-9 表格，因为我们不是美国实体。如果您的会计要求提供“W-9 或同等文件”，我们的 W-8 表格即为该同等文件。
