Shopify one-page checkout: native one-page layout vs a separate one-page checkout
Shopify's native checkout is one-page by default and can be switched between one-page and three-page layouts. A third-party external checkout is a different product decision, not just a layout switch.

Shopify's native one-page checkout
Shopify says one-page checkout collects the same core order, shipping and payment information as its three-page layout, and merchants can switch between the two from Checkout settings.
When layout is not the real problem
If you are searching for one-page checkout because you want a different payment processor, deeper control, custom tracking or another checkout domain, changing Shopify's layout alone will not solve those requirements.
Where Voss differs
Voss is a separate branded one-page checkout connected to the merchant's own Whop account. It does not simply reskin Shopify's native one-page checkout.
Official reference
Keep the store you built. Add the checkout you want.
Connect Shopify and Whop, test the full flow, then choose when you want to send live traffic through it.
