Product Upgrade in Checkout

Let shoppers upgrade to a bundle or swap to a better variant, right at checkout — without leaving the page.

If you sell bundles, kits, or tiered products, you've probably watched shoppers buy the single when the pack exists. Product Upgrade puts the option in front of them at the moment they're most committed.

How it works:

• A shopper reaches checkout with a product that has an upgrade path configured
• A dropdown appears in the order summary showing the bundle, premium variant, or add-on they can switch to
• One click. Cart updates instantly. No redirect, no re-entering info.

What you can configure:

• Trigger rules: Map any product to its upgrade — match by product, variant, tag, or collection
• Segmentation: Show upgrades to all shoppers or specific segments (first-time vs. returning, device type, custom)
• Appearance: Customize the dropdown label and styling to match your brand
• A/B testing: Test the extension on a segment before rolling out to everyone

Use cases brands are running now:

• Single cookie → cookie bundle
• Standard size → premium size
• Base product → product + stand or case
• One serum → full skincare set

Only shoppers with a matching trigger product see the upgrade prompt. Everyone else gets a clean checkout - no generic pop-ups, no irrelevant offers.
