I’m quite new to this topic. I sell on Amazon mainly and want to make good use of my inventory to fulfill orders on my website. I have linked google merchant to my existing Shopify store. I’m aware I can link amazon fulfillment to Shopify with the help of apps, so no question here. But when I’m setting up my Google Merchant, it is asking me how will I fulfill my orders, there are only 2 options, that is through companies Google work with like FedEx or not. So how should I answer this during set up? Do I even need to link Amazon multichannel fulfillment with my Google Merchant account at all?
If you don’t want to use Google Shopping, no, you don’t need to setup Google Merchant Center.
If you do, then you can only use Buy on Google with Amazon inventory lists: https://support.google.com/merchants/answer/9975850?hl=en
