What Is Shopify Plus? What It Changes at Checkout

Most Shopify stores start on a standard plan. Plus is for high-volume brands that want more say over their store. Your theme, products and admin stay the same. The big changes are in checkout and how many stores you can run.

What Plus Adds Over the Standard Plans

More checkout control. Only Plus lets app blocks, called checkout UI extensions, sit inside checkout itself, where shoppers enter contact, shipping and payment details. Other plans can only put them on the Thank you and Order status pages.
Expansion stores. Extra stores under one Plus plan, often for another country or a second brand.
Priority support. Your questions jump the queue at Shopify support.

Plus stores could once edit checkout code by hand, but Shopify has retired that. Changes now go through Shopify's Checkout Extensibility tools, which keep working when Shopify updates checkout.

Example: where a gift wrap offer can go

Say a candle shop wants to offer $4 gift wrap to people buying presents. On a standard plan, it can show the offer in the cart, before checkout. Once they're typing an address or card number, there's no spot for it.

On Plus, an app block can show it beside the order summary, right up to payment. If they say yes, the wrap joins the order they're about to pay for.

Why Checkout Access Matters for Offers

Checkout is where shoppers are closest to paying. An offer there can add to the order, or distract someone who was ready to buy. In our offer data from January to June 2026, checkout offers came from just 28 stores, all on Plus. About 9% of those offers were accepted. It wasn't a controlled test, and those stores may not look like yours.

Before adding anything to checkout, read our guide to Shopify checkout optimization.

Growth Suite, our app, uses this Plus-only access for a checkout offer progress bar and in-checkout upsells.

Myth: Moving to Plus Lifts Your Conversion Rate

Upgrading doesn't touch your theme, product pages or prices, so out of the box shoppers see the same store. You get more places to make changes, and those still have to be good.

You may see Plus stores with a higher conversion rate. Many are big, well-known brands, and a known name often brings more dedicated buyers who already plan to purchase. So the plan alone doesn't explain the gap.
