Needed to speed up the way I operated. I'm selling on Shopify and Etsy and was sick of logging in to each platform every time i needed to changed stock numbers. I did some looking online and found Shoplo Multichannel. It took like 5 minutes and I connected both my accounts and all my stock was updated. Now I get sale in Etsy, my quantity in my Shopify store goes down by one. Highly reccomended to anyone wanting to save time!
