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.
