CUSTOMIXEight field types
Text, long text, dropdown, single choice, multi-choice, colour, file upload and design picker. Each field gets its own rules, help text and character limits.
Features
From the form to the print file.
Personalization is more than adding a text box to a product page. Showing it to the customer, charging the right amount and getting a clean file into production are all part of the job — Customix covers the whole chain.
Set up
Build the form, assign it, publish.
No theme code, no developer, no copy-pasting snippets into Liquid.
Reusable option groups
Define an engraving form once and assign it to as many products as you like. No rebuilding it product by product.
No theme editing
The form ships as a Shopify app block. It survives theme updates and works on Online Store 2.0 themes.
Four presentation styles
Minimal, Cards, Compact or Studio — plus accent colour, corner radius and spacing, all from the theme editor.
Conditional fields
Show the engraving text box only when the shopper answers "yes" to wanting engraving. Offer options without crowding the page.
Storefront
Shoppers see it before they buy it.
Live preview on the real product photo — not an abstract mockup.
Live preview
The shopper's text and artwork appear on the actual product photo as they type. Front, back and sleeve are separate surfaces.
Takes over the gallery
The preview isn't stuck in a small box — it takes over your theme's main product gallery.
Drag and resize
Shoppers position and scale their own artwork inside the area you allow. You set the boundaries and the minimum and maximum size.
File uploads
JPEG, PNG, WebP, SVG and PDF up to 20 MB. Files land in private storage and you download them from the admin.
Design library
Upload your own logos and patterns, or import public-domain artwork from The Met. Shoppers pick from a grid or carousel.
QR codes and barcodes
QR, Code128, EAN-13 and UPC-A from a fixed value or whatever the shopper typed — rendered in the preview and in the print file.
Pricing
Charge for personalization.
Rules are evaluated on the server, so the price can't be tampered with.
Eight rule types
Charge per field, per choice, per character, per quantity, per upload, per design or per surface. Combine them however you price.
Live price breakdown
Shoppers see each add-on itemised as they choose. No surprise at the cart.
Server-side pricing
Prices are computed on the server, never in the browser. Nobody discounts your add-ons with devtools.
Production
Every order comes back ready to print.
The queue, the frozen record and the print file are all in the app.
Production queue
Every order becomes a record you can move through new, in review, approved, in production and completed. Search and filter included.
Print-ready files
300 DPI PNG or PDF per surface, optionally with bleed, safe-area guides and trim marks.
Frozen at checkout
What the shopper bought is locked the moment they check out. Change a template tomorrow and yesterday's order still prints exactly as sold.
Field types
Eight types, all built in.
Every field can be required, carry help text, enforce a character limit and have its own price rule.
Text
One line — a name, a date, a short engraving
Long text
Multi-line notes or messages
Dropdown
Long option lists without the clutter
Single choice
A few options, all visible at once
Multi choice

Shows a swatch, submits the name
File upload
