I'm pretty sure Patreon takes care of EU VAT: https://support.patreon.com/hc/en-us/articles/205259549-How-...

I'm not sure about Zoom, but since their FAQ includes info on EU VAT, I assume they have taken care of it, too: https://support.zoom.us/hc/en-us/articles/360021487812-EU-VA...

Zoom charges VAT based on the local country (or based on the VAT number if you are a company and provide one)

Patreon shows VAT and total price in the checkout page, I've yet to use a service that didn't. (EU person here)
