advanced commerce and abandoned cart feature - surely it won't work???

This is my third – and I guess/last question.

I was looking at getting the advanced commerce – for one of my websites.

But there is ONLY one thing that I actually want it for – and that is abandoned cart.

Then I thought about it for a bit… surely that feature won’t work [for me]? I’m selling tickets to a show. But if the tickets are [for example] on sale through Ticket Tailor – surely there’s no way that Squarespace can do the abandoned cart feature – becayse in fact the tickets are not ‘run’ by them?

Or am I wrong about that whole assumption???

I am often wrong, and I hope I am here. So please do tell me if my thinking is silly and wrong. Thanks again
