Hi,
Thanks for the interest in our plugins. I can answer your questions.
We do not have any features to integrate with Quickbooks. If you use WooCommerce through Event Tickets Plus then all the sales data is in WooCommerce and they might have a feature to export to Quickbooks, but that is not something we support.
If you think that is something you would like as a feature I encourage you to visit our User Voice Page and either upvote an existing request or make a new request there.
