Hey there, I have gone your project description about Shopify dropshipping from USA and Canada Suppliers. I believe, I can assist you in this regard.
Dropshipping is not the rocket science, you just need to work on strategies and on right direction.
I have great experience in dropshipping. For Shopify, some of the methods we mostly use are:
The First is from "Banggood" (Here stock is always limited, Shipping time is 2-8 days, Shipping service is USPS, profit margin is lesser than Ali-Express but quicker and usa tracking number is beneficial).
The second most we use is from "Amazon prime" (Here items shipped from usa Amazon warehouse, Shipped within 3 days, Shipping is free on 35+ $ order. This is quickest delivery dropshipping. Profit margin is not much but better).
However, we can also approach USA suppliers from other platforms like, Walmart, DHgate, Oberlo etc. according to business niche too.
If we choose multiple methods, we will get best results profit/ earning wise, delivery wise and quality wise. We pick suppliers which have quickest dispatching time with well reputed feedbacks.
Before starting this journey,
Would you like to share your business niche/sub-niche? So I can make a profitable and proper pan for you. ALSO, let me know what specific marketplace initially you are planning to target for Google ads?
Furthermore, I would like to chat with you to get a better understanding of the project. I look forward to hear back from you sooner. Thank you!
