# New: Product Upgrade Checkout Extension

Let shoppers upgrade to a bundle or swap variants right at checkout

April 28, 2026

Product Upgrade is a checkout extension that lets shoppers upgrade a single product to a bundle — or swap to a different variant — without leaving checkout. It shows up as a dropdown in the order summary, tied to the specific product in the cart.

Built for bundle-heavy merchants. If you sell a single item that also comes in a pack, a kit, or a premium version, Product Upgrade gives shoppers a frictionless way to level up at the moment they're most committed.

# How it works

1. A shopper adds a product to their cart and reaches checkout.

2. If that product has an upgrade configured, a dropdown appears in the order summary — showing the bundle or variant they can switch to.

3. The shopper selects the upgrade. The cart updates instantly. No redirect, no re-entering info.

# What you can do with it

- **Single → Bundle:** One cookie → cookie bundle. One serum → full skincare set.
- **Variant swap:** Standard → Premium. Small → Large.
- **Add-on upgrade:** Base product → product + stand, frame, or case.

# Segmentation

You control which products trigger the upgrade prompt. Only shoppers with a matching product in their cart will see it — no generic pop-ups, no irrelevant offers. You can restrict upgrades to specific product tags, SKUs, or collections.

# Where to find it

Go to **Checkout Content > Extensions > Product Upgrade**.
