I’m Helen from Shopify Support. Welcome to the Community!
A quick way to find specific apps is to actually use Google. Their search function is so sophisticated, that a search of ‘Breed Business Fulfillment Shopify App’ will take you right to it!
Therefore, it appears as though the app you are looking for is now listed as Dropshipping & Print on Demand in the Shopify App Store.
This looks like a very interesting app to help create a niche dropshipping product, by the way. Do you already have products or designs in mind?
As you setup your store and begin to choose your products, I recommend reading this Help Doc on Preparing for a dropshipping business for some great guidance.
Hope this helps! Let me know if you have any further questions.
I am now having a separate issue and hoping you'd help me. I have set up my store and integrated Paypal too, but at the time of check out, I see the below error message.
"There was a problem with our payments. Contact Us to complete your order". I've been running around in circles for days, and finally thought I'd ask for your help.
