No, payment gateways and shopping carts are not yet available. Patience is what we need. The Thrive developers are always adding new features and updates to their products. So we can only be positive. That said, I highly recommend ThriveCart for your shopping cart which integrates with Stripe and PayPal (it includes an awesome affiliate management system as well)… that’s what I’ve personally used for the past few years and it’s really good (works well together with Thrive Theme Builder and other Thrive products).
