Use cases

When to reach for this.

01

Last-chance upsell

Highest-intent moment in the funnel — one extra product at checkout changes your economics.

02

Trust reinforcement

Guarantees, shipping policies, or testimonials shown where buyers second-guess themselves.

03

Compliance / disclosure

Age gates, subscription disclosures, regional policies — handled natively.

How it works

Social Proof Where Doubt Lives

Build trust with customer reviews and stories displayed right at checkout. When buyers see real testimonials from people like them at the moment of decision, abandonment drops and confidence soars.

Implementation

  • Rotating testimonial widget in checkout sidebar
  • Pull from your existing review platform or custom entries
  • Star ratings, customer photos, and verified badges
  • Mobile-optimised layout

FAQ

Quick answers.

Do I need Shopify Plus?+

Most Checkout UI Extensions work on all Shopify plans. A few customisations (full function modification) require Plus — we'll tell you upfront which category your project falls in.

Will Shopify updates break this?+

No. Checkout UI Extensions are Shopify's officially supported extensibility API — they're future-proof by design.

Can I edit the text myself later?+

Yes. All copy lives in theme settings or the admin — no dev needed for text edits.
