Checkout Master docs

Checkout Master helps your Shopify checkout sell more, build buyer trust and carry your brand, from the moment a buyer checks out to long after the order.

What it does for your store

What your store needs

Most of it works as soon as you install. A few parts depend on your Shopify plan or a setting in Shopify:

• Blocks on the checkout page, and Style: Shopify Plus. Shopify only lets Plus stores change the checkout page itself. That's Shopify's rule, not ours.
• Blocks on the thank-you and customer account pages: every plan except Shopify Starter.
• Customer account blocks: your store needs Shopify's current customer accounts, not the legacy ones. Only stores already on the legacy version before February 2026 can still be on it; check under Settings › Customer accounts, or see Shopify's upgrade guide.
• Post-purchase offer and survey: any plan. Choose Checkout Master under Settings › Checkout › Post-purchase page.
• Style: the staff account you use needs the Manage checkout settings permission. Store owners have it; for anyone else, the owner turns it on under Settings › Users.
• Rules: any plan, nothing to turn on. The app adds itself to Shopify's delivery and payment customizations for you.

The app checks your plan for you: anything your plan can't use is shown locked, with the reason, not hidden.

What it never does

• Blocks only ever add to a page. Nothing in Checkout Master can stop a buyer checking out.
• Nothing is added to a cart or an order unless the buyer taps to add it.
• No countdown timers, no ads, and no request for card details.
