Hi, I am selling marketing services including website design, social media management and content writing on my Shopify site. I'm based in the U.S. I may expand and also sell digital products, like stock photos (but am not selling them yet). I have had a potential client inquire about my social media management services. He is a business owner located in France. Do I have to charge him a VAT tax? And if so, do I have to be registered in the EU to charge him this tax?
