Why it matters
Built to move the metric you actually care about.
Native to Shopify Checkout

Adds without distracting
Appears in the right slot — info blocks, upsells, guarantees — without breaking checkout flow.
Works with One-Page Checkout
Fully compatible with Shopify's newer checkout UX and Shop Pay.
Use cases
When to reach for this.
Last-chance upsell
Highest-intent moment in the funnel — one extra product at checkout changes your economics.
Trust reinforcement
Guarantees, shipping policies, or testimonials shown where buyers second-guess themselves.
Compliance / disclosure
Age gates, subscription disclosures, regional policies — handled natively.
How it works
Custom Checkout Inputs — No App Required
Give your customers the ability to append information to their order right at checkout. Whether it's a gift message, special delivery instructions, or a marketing opt-in — this native checkout extension handles it without third-party apps or page reloads.
Why It Matters for Conversion
Shopify's default checkout is rigid. Adding a simple checkbox — "This is a gift" or "I agree to subscribe" — creates a more personal experience that reduces post-purchase support tickets and increases opt-in rates by up to 22%.
How We Build It
- Native Shopify Checkout Extension (no app bloat)
- Fully customisable label, position, and default state
- Data captured in order metafields — visible in admin and fulfilment
- Works with Shopify Plus and non-Plus stores
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.
