No code. No theme edits. Answers land on every order automatically.

Text, dropdowns & file uploads

Let shoppers add monograms, gift notes, and engraving text, choose from preset options, or upload their own artwork and photos — right on the product page. Every answer is captured as an order line-item property, so it appears on the order, packing slip, and in your fulfillment workflow.

One-click theme block — no developer needed

Kustomly installs as a native Shopify theme app block. Drop it onto your product template from the theme editor, set your heading, and you're live — no code, no Liquid edits, no risk to your theme.

Never miss a required detail

Mark any question as required and Kustomly blocks "Add to cart" until the shopper fills it in — so you never get an order you can't fulfill. Control which questions appear and how they behave from a simple settings page.
