For some of my customers in the additional info I have their VAT number saved which is not added to the new invoices and statements. This happened only this month

Let’s walk through some troubleshooting steps to ensure your VAT numbers appear on your invoices and statements, Accounts632.

In QuickBooks Online (QBO), customer VAT numbers will automatically appear on invoices and statements if VAT is configured in your account and your products or services are assigned a VAT rate.

Since the issue has started only this month, it could be a temporary technical browser issue. To troubleshoot, suggest switching to incognito mode. Sometimes, cached files in your browser can interfere with QBO's functionality, potentially causing display issues such as VAT numbers not appearing as expected.

After using an incognito window, restart your browser to clear out any outdated processes and ensure the updates take effect. A supported and up-to-date browser can also improve performance and security when working with QBO.

If the issue persists, I recommend reaching out to our Live Support team, as they can securely screen share with you to investigate and fix the problem directly.

Please feel free to revisit this thread with any updates or further questions.
