OrbitKit makes it easy to sell multiple different products in a single listing. For example, you could sell a t-shirt, long-sleeve tee and hoodie in the same listing.

Here's what it looks like at Shopify:

Setup

After you have created a blueprint for Shopify or Etsy, you can add additional products:

Price, print side, and color assortment is specific to each product.

Things You Should Know

Multiple-product listings behave slightly differently from single-product listings:

The default behavior of adding the product name to the end of the listing title is disabled. You can still create custom title patterns with blueprint text templates.
Similarly, a product description is not appended to the listing description. You can customize this with text templates.
You can control the order of products in the listing using the arrow buttons.
Just as with colors, you can change your blueprints to add/remove products and re-synchronize your listings.

Things You Should Know - Shopify

Shopify lets you have a maximum of 100 variants in a single listing. With variations of product, color, and size, this adds up fast. If you want more products, offer fewer colors. OrbitKit won't let you add more than 100 variants.
Shopify shows the customer a combined list of colors. Customers will have an easier time navigating their purchase if every product has the same available colors.
OrbitKit will include a size chart for every product you include.

Things You Should Know - Etsy

Etsy allows a maximum of 10 images in a listing, one of which must be a size chart. If you have too many products and/or colors, some will not have mockup images.
Etsy does not allow HTML in descriptions, so OrbitKit uses one of the image slots for a size chart. OrbitKit will stitch together size charts for all of your offered products into a single image.
You can configure how variations are presented to the customer.
Etsy has a limit on the number of values a single variation can have. You can hit this by selecting too many colors, but it's hard to predict exactly how many colors are allowed. See the above document on variations.
