No, I mean something more like the attached photo where everything is on one page. One reason is that the authentication doesn’t kick in until the last step of the checkout, so if you’ve made a mistake on the page with your name, email, phone, etc. then you have to get back to that page somehow.
Also, the research I’ve seen shows more sales with a single page checkout process compared to a step-wise process like the one in the template.
Anywho, we’re pretty savvy, and so if you could point us to anything that covers the principles of how you set up the checkout with this theme, and/or how we might be able to change it without breaking anything, we could probably handle it from there.
