Howdy Gwenaelle,
Good question. Looking back through our forums I have never seen any reports of incompatibility with Product Vendors, even though a number of folks are evidently using it. It looks like they should work fine together. While I can not guarantee compatibility we do offer a 30 day refund window, and you can easily take advantage of that if you discover somethings not working like you hoped.
The sales reports in WooCommerce work perfectly for Tickets as well, that is completely compatible. In addition if you are using Community Ticket (click here for screenshots) you will find that each event has its own sales report that indicates how much money you made, and how much the organizer made.
Does that answer your question? Please let me know.
Cheers!
