Hi there!
Thank you for reaching out. At the moment, the plugin uses the WooCommerce order ID (post ID) for Analytics tracking, and compatibility with plugins such as Sequential Order Number for WooCommerce is not currently built in.
I can understand how seeing the sequential order numbers in Analytics instead of post IDs would be more helpful for store management and reporting consistency.
This can likely be achieved through customization. However, customization is outside the scope of support we are able to provide here.
Since this is not currently supported out of the box, I’d recommend submitting it as a feature request so our development team can review it for future consideration:

Thank you for understanding.
