I get it takes care of content and they mention Stripe, so that is good. But is this WP compatible layer or this is accidental use of shorthand for something else?
It is more like those templates that people use to jumpstart sites, I think this can be very useful.
I don't want to sound too complainy over the free code you can get and examine yourself, maybe adding thumbnails of 3 templates would be fantastic.
Overall some clarity would be great, maybe developer should talk to someone outside his little circle and explain and see what they should include.
