Checkout Ecommerce Website Builder | Webflow and see if it fits all of your clients needs. Try to think of everything before deciding on it, since the WF e-commerce still pretty new and lacks a few features
The ecommerce functionality on Webflow isn’t currently geared towards ticketing. You can do it, but it doesn’t let you do simple ticketing things like limiting the quantity of tickets a user can purchase.
I’ve also used TicketSpice, but have found that their styling and embed functionality aren’t quite up to the style desires that Webflow users have come to expect.
I appreciate you asked this question a lot time ago, but I thought I’d add another option incase other people stumble upon this post.
Philip (the above poster) is right that Webflow commerce isn’t really made for selling events and ticketing. Like most ecommerce platforms it is built for selling ‘products’.
I will openly admit I am massively biased (I’m the founder) but Event Calendar App works great for this as it was built for exactly the reasons you are asking for. It allows you to add an event platform to your website to sell tickets to your events. It looks great (like you would expect), doesn’t take people away from your site, and has a monthly fee rather than individual transactions fees.
Here’s a picture of an example Webflow site selling yoga events:
