The Chargebee checkout & portal pages can be customized in several ways to suit your requirements. To edit the default fields or labels, follow the steps below:

1. Navigate to Settings > Configure Chargebee > Checkout & Self Service Portal

2. Click on the "Labels" tab

3. Click on the label that says “Pay [Amount] & subscribe” and edit the text based on your requirement

If you’re looking to edit the name of any other buttons or fields on the checkout page or self-service portal, you can find the required label from the checkout or portal pages using the “Add more copy/text” option.
