One last chance, gracefully delivered
The Checkout Popup intercepts the Checkout click with a last-chance offer. No nagging, no friction — just a clean modal with a clear value proposition.
Customers can add and continue, or skip in one tap. Either way, they reach checkout in seconds.
- Triggered by Checkout button click
- Optional discount on the offered item
- Skip button always visible — never aggressive
Polished, never desperate
Checkout-trigger
Fires only when the customer clicks Checkout. The highest-intent moment in the funnel.
Inline discount
Offer a small discount on the popup item — customers see the savings before adding.
Frequency caps
Show-once-per-session logic so returning customers don't see the same popup twice.
Themed presets
12 polished presets, fully customizable. Matches your storefront visually.
Smart targeting
Different popups for different cart values, products or customer tags.
Zero code
Enable via app block — no theme edits, no developers needed.
