Good evening Alexandre and welcome to the Events Calendar forum!
Thank you for your interest in our products.
We’ll be glad to answer your questions.
want to make sure that i will be able to use it in France, in Europe, all over the world? Are there some restrictions? Do you guarantee full compatibility I guess so?
As far as we know, you should be able to use our plugins all over the world.
You will simply need to make sure you adhere to the regulations in place in the country of your company’s headquarters.
For instance, I believe that in France you need to abide by VAT taxes rules: https://theeventscalendar.com/knowledgebase/woocommerce-and-vat-taxes/
Most of our users choose WooCommerce as a solution for this (which integrates perfectly with our Event Tickets Plus plugin). Mostly because it lets you deal with different taxes, shipping and such.
In short we hand over all of the transactional aspect of things to WooCommerce.
Let me know if that helps.
Have a great day!
Geoff B.
