"I run a small vintage shop on my own and since I sell the same items on multiple platforms I am always worried about not noticing a transaction and accidentally double selling. This site solves that problem for me completely. All I have to do is assign the same sku to each item and I can rest assured that if it sells on one platform it will immediately be made unavailable on the others. I personally link a Shopify site and an Etsy site and after a few hours of learning my way around the site I find it very easy and seamless! Thanks for making running a small business on your own a little less stressful."
