CornerCart vs UpCart

UpCart and CornerCart cover a lot of the same ground: a full cart drawer, tiered progress bars, free gifts, Buy X Get Y, and volume discounts. The differences are in how offers are run and what stands behind the app. Here is the honest breakdown.

Where CornerCart pulls ahead

One campaign engine for everything

Gifts, thresholds, announcements, and upsells all share the same targeting and scheduling system: by market, customer tag, cart contents, or date range.

Backed by a revenue guarantee

CornerCart comes with a revenue guarantee: 12% or your money back. You're not paying for a cart app on faith.

Built to be customized

Visual theming covers most brands; custom HTML/CSS blocks and a JavaScript SDK cover the rest. Your cart can look and behave exactly how you want.

Switching takes an afternoon

You can run both apps side by side while you rebuild your offers.

1

Install CornerCart and style the drawer

Pick a theme preset and match your brand. Your existing cart keeps working meanwhile.

2

Rebuild your offers as campaigns

Recreate your gifts, thresholds, and upsells. Most merchants finish in under an hour.

3

Enable CornerCart, disable the old app

Flip the app embed. Nothing is left behind in your theme code either way.

I even went through the process of setting up a different, more expensive app — and it only had a fraction of the customisations and flexibility of this app. Customer service is super helpful, highly responsive and patient with all my questions.

Frequently asked questions

Can I run CornerCart and UpCart at the same time?

Yes, while testing. Keep CornerCart's cart replacement disabled until you're ready, then switch over in one step. Long term, running two cart apps is not recommended.

Will uninstalling my current app leave code in my theme?

CornerCart installs via Shopify app embeds and leaves nothing behind on uninstall. Check your current app's documentation for its own cleanup steps.

Do I lose my existing offer data when switching?

Offers are rebuilt as CornerCart campaigns, and most take minutes each. Our support team helps with migration on any paid plan.
