I need to export invoices as XML and integrate into Peppol - any ideas?

Welcome to the Community, jules.

QuickBooks Online (QBO) doesn't have a built-in feature to export invoices as XML or connect directly to Peppol. However, you can export invoices from QBO as a CSV file. Once exported, you can use specialized third-party software or apps to convert the CSV into XML format compatible with Peppol standards.

To enable integration, explore third-party tools that offer XML conversion or e-invoicing features. Some of these tools are available in the Intuit App Store and can help you connect QBO with Peppol. This approach allows you to meet necessary standards using external solution. 

For more questions about QBO, feel free to reach us out. We're always happy to help.

Where is your company located? As i know Peppol doesn't support HRMC.
