Questions about Shopify Plus

What can be customized in Plus checkout?

Fields, offers, messages, delivery and payment options, validation and discounts, with checkout UI extensions and Shopify Functions. The checkout page itself stays Shopify's, so it keeps its speed and its security.

When is it worth moving to Shopify Plus?

When you need checkout customization, Shopify Functions, native B2B, more staff accounts or markets at scale, and the volume covers the plan. If it does not, we say so in the first call.

Do you use your own app in Plus checkout?

Yes. Checkout Upsell Builder (Plus) by Developpy is live on the Shopify App Store and runs on the same checkout extensions we build for client stores. If your case needs something it does not do, we build a custom extension.

How long does a Plus project take?

It depends on how much the checkout must do and on what moves to Plus. You get a launch date in the written scope before work starts.
