Building a custom checkout flow for an Aura store
Key Takeaway
In a B2B store created with the Aura template, you customize checkout by changing the B2B checkout flow, and you add steps with core actions from the "B2B Commerce" category in Flow Builder.
A custom checkout for an Aura store starts from the B2B checkout flow, which takes the cart all the way to an order. Changing the flow changes how checkout works for buyers.
Checkout in an Aura store
For a B2B store created with the Aura template, you edit checkout with flows instead of designing the Checkout page with preset checkout layouts and sections.
The B2B checkout flow is a managed checkout flow that processes the cart's shipping, inventory, pricing, and tax integrations. After those integrations, the flow converts the cart to an order.
