Good afternoon Xavier and welcome to the Events Calendar forum!
Thank you for your interest in our products.
We’ll be glad to answer your questions.
1 – Can I use it with the regular plugin Event Calendar or do I need The Event Calendar PRO plugin?
You can use Event Tickets Plus with the Events Calendar. You do not need the Events Calendar Pro (although that works too).
2 – Do I have to use an e-commerce plugin if I use Event Ticket Plus? The main functionality that I’ll use for the Event Ticket Plus plugin is the QR Code in tickets. I don’t need the e-commerce plugin / selling tickets. All the tickets will be free.
No, you do not need to use an e-commerce plugin if all your tickets are free.
This means you will be using “boosted” RSVP tickets, thanks to Event Tickets Plus.
Another alternative would be to use something like WooCommerce (for its added benefits – reporting, tracking, etc…) and use products that have a cost of zero (free).
3 – If I just want the QR Code functionality, do I need to buy Event Ticket Plus? (I don’t find it in the regular Event Ticket plugin)
Yes, you need to get a copy of Event Tickets Plus to have QR code scanning abilities.
Best regards,
Geoff B.
