Let's say you want to rely on Chargebee checkout only to collect the payment details from the customer. You can configure your Checkout as a one-step checkout to collect the payment method.
You can use a single-step checkout when you provide subscriptions with a single plan. For example, Acme industries sell a yearly subscription for licensed software.
You can achieve this by disabling all field settings other than Payments, and your Chargebee hosted Checkout acts as a secure payment collection page.
To use your Chargebee's hosted Checkout as a single-step checkout, navigate to Settings > Configure Chargebee > Checkout & Self-Serve Portal > Fields and disable all field sections other than Payments.
See the video below to enable your customers to do single-step Checkout.
