Listing Custom tee shirts from Printful on Google Merchant Center / Google Shopping

Hi, I have an online store that utilizes print on demand services like printful to handle the fulfilment of my products. I integrated with Shopify and all my listings are active on shopify and Printful.

Question:
Which app is best for integrating with Google Merchant so that I don’t have to manually input certain aspects of the clothing such as size, color, gender, GTIN, etc.?

Notes:

  • I have variations in color and size for all of my product so entering a manual color and size would presumably restrict my listings from showing up in a number of searches.
  • I am currently using the Google & Youtube shopify app and there are a number of issues.

Expect a high propability of getting suspended, reason is that Google expects the finished product to be stocked, which POD is not, reference: https://support.google.com/merchants/answer/6150127#:~:text=Unavailable%20promotions

However if you do want to test it, and you are ok with getting potentially suspended (please note this can transfer over to Google Ads) is to use: https://apps.shopify.com/multiple-google-shopping-feeds

This app if you use the correct attribute names for color and size, will automatically import.

The gender, may not and you may need to manually setup the rule to get the attribute.

The barcodes will also automatically import.
