We've used Synkro for about 6 months now to sync inventory between our 2 Shopify stores. While it works well 95% of the time, sometimes it causes inventory issues.
For example, let's say we have 50 of a product in inventory. Our inventory will show 50 in stock on both store 'A' and store 'B'. A customer places an order on store 'A' for 4 items, leaving the inventory at 46 on store 'A'. Synkro will then subtract 4 items from store 'B' so it matches at 46. However, sometimes, rather than subtracting 4 from store 'B' to make it match store 'A', it will add the 4 items back in to store 'A' to make it match store 'B' and our inventory will now show 50 in stock on both stores again when we physically only have 46.
This has happened several times now, and unless you manually go back through the inventory history of every product on both stores, there is no way of know when it occurs until you oversell.
Need to have an option within the app to set it to NOT add inventory back in unless triggered by an inventory transfer or manual inventory adjustment by store personnel. The app should not take it upon itself to add inventory back in without a triggering event.

Thank you for your review! I would love to work through this issue with you. Would you be able to send some screenshots of the inventory history on a product the next time this happens? Please send these screenshots to and we can work out what the problem is together :)
