Wordpress + Laravel Backend ??

Hey Guys,

I am in the process of setting up an eCommerce store on a WordPress for the e-commerce and Laravel for the backend only accessible for people with active subscriptions,

I am having the hardest time figuring out how to use Laravel auth system vs WordPress but have laravel check to make sure user has active sub.

I found that laracast has a system on accepting payments https://laracasts.com/series/how-to-accept-payments-with-stripe

was thinking if it would be easier to setup the ENTIRE site via laravel or do the 50/50 mix Wordpress/Laravel

What do you guys think?
