Shopify App Store

What are You Looking for?

Your print-on-demand app creates a separate product for every color. Here is how to connect them.

You design a t-shirt. You publish it on Printify or Printful in 12 colors. Your Shopify store now has 12 separate product listings. A customer finds the blue one. They like the design but want it in green. There is no swatch, no link, no way to switch colors. They have to search your store and hope they find the green version.

This is how every print-on-demand store works by default. POD apps create separate Shopify products for each color or design variation. The products are not connected to each other in any way. Customers see individual listings, not a unified product with color options.

Combined listings fix this. You group those 12 separate products and add color swatches that let customers switch between them on the product page and in your collection pages.

The print-on-demand product problem

A typical POD workflow looks like this:

  1. You create a design in your POD app (Printify, Printful, Gooten, SPOD, or similar).
  2. You select which products to put it on: t-shirts, hoodies, mugs.
  3. You pick colors: black, white, navy, heather grey, forest green.
  4. The POD app publishes each color as a separate Shopify product.

Your store now has 5 separate listings: “Mountain Sunrise Tee – Black”, “Mountain Sunrise Tee – White”, “Mountain Sunrise Tee – Navy”, and so on. Each has its own URL, its own product page, its own set of mockup images. But there is nothing connecting them.

A customer browsing your collection page sees 5 separate product cards for what is really one design. If they click the black version and decide they want navy, they go back to the collection, scroll, find navy, and click again. That is a lot of friction for a simple color change.

Why POD apps create separate products

POD apps have a good reason. Each color has its own mockup images, its own print file, and sometimes its own pricing. Printful and Printify manage inventory and fulfillment per product. Keeping them separate makes the supply chain simpler.

Some POD apps can create a single product with color variants, but this has limits. The mockup images get mixed together in one gallery (40+ images for 8 colors). And if you want different designs per color (not just different blank colors), separate products are the only option.

The problem is not how the POD app creates products. The problem is that Shopify has no built-in way to visually connect separate products. That is what combined listings solve.

What combined listings do for POD stores

A combined listings app groups your separate POD products and adds color swatches. The customer lands on the black t-shirt page and sees swatches for white, navy, heather grey, and forest green. They click navy. They go to the navy product page with navy mockups. Each product keeps its own URL, images, and SEO.

On collection pages, swatches appear on each product card. Hovering over a swatch changes the product card image to show that color. The customer can preview all colors without leaving the collection page.

This works for any POD app: Printify, Printful, Gooten, SPOD, Gelato, CustomCat, or any other service that creates separate Shopify products.

How to set it up with Rubik Combined Listings

Rubik Combined Listings Swatch works on every Shopify plan. Free plan includes 5 product groups. Here is the manual setup for a single group:

  1. Install the app and activate the app embed on your theme.
  2. Create a product group. Name it after your design (“Mountain Sunrise Tee”). Set the option name to “Color.”
  3. Add your POD products. Search and select all 5 color versions.
  4. Click Magic Fill. The AI reads your product titles and images, then fills in the option values (“Black”, “White”, “Navy”) and picks matching swatch colors automatically. No typing.
  5. Save. Swatches appear on all 5 product pages and on their collection page cards.

5 minutes per group. But if you have 50 designs in 8 colors each, that is 50 groups to create. For that, use bulk grouping.

Bulk grouping for POD: auto-detect from product titles

POD apps typically name products with a pattern: the design name, then a separator, then the color. Examples:

  • “Mountain Sunrise Tee – Black”
  • “Mountain Sunrise Tee – White”
  • “Mountain Sunrise Tee – Navy”
  • “Ocean Wave Hoodie – Forest Green”
  • “Ocean Wave Hoodie – Heather Grey”

Rubik’s bulk grouping feature auto-detects these patterns. It reads your product titles, finds the separator (dash, pipe, or slash), splits the title into group name and option value, and creates all your groups at once.

The detection uses a 4-pass algorithm:

  1. Normal direction: “Mountain Sunrise Tee” = group name, “Black” = option value.
  2. Reverse direction: For titles like “Black – Mountain Sunrise Tee” (color first).
  3. Fuzzy word matching (prefix): “Mountain Sunrise Tee Black” and “Mountain Sunrise Tee Navy” share the prefix “Mountain Sunrise Tee.”
  4. Fuzzy word matching (suffix): “Black Mountain Sunrise Tee” and “Navy Mountain Sunrise Tee” share the suffix.

Case-insensitive. “Mountain sunrise tee – black” and “Mountain Sunrise Tee – Blue” merge into one group.

A store with 50 designs and 8 colors each (400 products) can create all 50 groups in a single bulk operation. Preview the results before confirming, adjust anything that looks off, then create all groups at once.

If your POD app does not use a consistent naming pattern, you can also group by product tags or metafields. Tag your products with RUBIK::Mountain Sunrise Tee::Color::Black and the app groups them accordingly.

The SEO benefit for POD stores

Having separate products is actually better for SEO than cramming all colors into one product with variants. Each product gets:

  • Its own URL that can rank for specific keywords (“navy mountain sunrise t-shirt”)
  • Its own meta title and description
  • Its own entry in Google Shopping feeds
  • Its own mockup images indexed in Google Images

Combined listings add internal cross-links between the products (each swatch is an HTML anchor link). This tells Google the products are related and distributes link equity across your catalog.
