How much would it be charged if I upgrade my Zoom Webinars from 1000 to 3000 attendees?
We will be holding a Zoom Webinar next week, and we don't have the full attendees list yet. So we will subscribe for 1-month Zoom Webinars with 1.000 attendees (USD 340/mo).
Let's say that 2 days before the event we have a surge of attendees, so I have to upgrade to 3.000 (USD 990/mo).
How much will we be charged for the upgrade?
USD 650 (the difference between 340 and 990)? Or USD 1330 (340 plus 990)?
Thanks!
