Custom Caps Co. review for Syncio Inventory Sync

I purchased this app to help manage my product stock on both my Canadian and American Sites. The first test I did went very well and I was so happy with how it managed my inventory. Today I did a huge restock and the app allowed SOLD OUT ITEMS to be sold (i'm not dumb they were set to not allow purchasing after being sold out). All my items were going to -1 and -2. I'm so beyond frustrated as I have had to remove all my inventory to ensure no more out of stock items were sold. This has created a plethora of problems for me and has really damaged my reputation to my customers. I would recommend trying a different app.
