Can I edit the Squarespace Checkout?

No. The Squarespace checkout is locked down to ensure it remains secure and PCI-DSS compliant. It cannot be modified in any way, including HTML, CSS or JavaScript.

PCI-DSS compliance is a security standard for companies and organisations that handle payment information from consumers. Both of Squarespace’s payment processors, Stripe and PayPal, are PCI compliant.
