Good evening GeorgeĀ and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
I would love to help you with this topic.
what the difference would be just having WooCommerce by itself. What advantage(s) does ET+ provide besides event & product in one step rather than two?
You are right, cutting things down to 1 step is clearly one of the big differences between the 2 approaches. But there is more.
You get the Sales and attendees reports tied to the events as well.
Furthermore, you also get check-in abilities (manual or with a QR code).
You can also extend our plugin with a few snippets or extensions to do things such as a bcc of orders to the event organizer or a person of your choice.
But, what is probably our most popular feature is the fact that you can request additional attendee information as part of your tickets, built-in.
Let me know if that helps.
Have a great day!
Geoff B.
