2 key pieces of tech you need are…
1. Landing page software to create the webinar registration page.
I recommend Lead pages for this – sign up for a free trial here: https://www.leadpages.net/
2. Webinar software
Zoom webinar is the most robust and trusty piece of software I’ve used (please note that this is different to Zoom Meeting and requires an add-on). $54.99 a month
demio.com – a fairly easy to use piece of software for webinars $49 a month.
When I’m taking payments from webinar sales, I very simply use a Thrivecart checkout page. Thrivecart is currently available on a lifetime deal for $695 and you’ll never pay again (limited special offer) Choose the Pro version
