Registration Form

I’m trying to help a yoga studio client replace an off-site registration system she’d been paying a monthly fee for with a built-into WP application. I had thought I’d use Gravity Forms for the registration form and then use WooCommerce for them to purchase whatever class bundle(s) they wanted. I’m struggling with how to make them work together and not really wanting folks to have to complete a lengthy reg form every time. I stumbled on your plugin and am trying to figure out if it’ll do what we need.

It looks like I could create a registration form they’d fill out once then then when logged in they’d be able to purchase whatever classes they wanted. Is that the basic system? And is the registration form customizable? That was why I was going to use Gravity Forms. Seems like if I can make your form work then I just use WooCommerce for the products (class bundles).

Am I seeing this accurately?
Thanks,
