syncX Stock Sync Inventory CSV

So I don't usually write reviews, but I felt compelled to write one about Stock Sync. I run a store with over 20,000 skus, and had tried a number of different options to update stock prior to finding this app, all of which were VERY time consuming. I had been using the Shopify product upload csv file, which is fine is you are running less than 1000 skus, but even then it has some issues (image maintenance for a start if you aren't using hosted images).
Stock Sync has been a real blessing and worth every penny! The updates are so simple, and now with the enhanced features you can update more than just stock levels, all with a simple drag and drop and the update for over 20,000 skus is quick!
If you have a large inventory, or have inventory from multiple suppliers this is an absolute must!!
