Is there a ready-made solution for connecting a shopping cart and billing on Rails?

Question

Ruby on Rails

Good day!
We make a booking service for playgrounds. That is, there is no product as such, there is a bookable time and payment for the reservation. To speed up development, we are looking for a ready-made basket + billing on Rails.
Tell me please!

Answer 1

E-Commerce and Payments: Online Shops - for review.
Perhaps RoR eCommerce would be a good option. At least borrow ideas from there.
