Thank you for taking the time to answer my query. Did you see the notes on the right hand side of the order created by the Yith POS plugin. It says or looks as though it has deducted the stock in woocommerce but I am assuming at this point that these notes on the right hand side are woocommerce.
Yes, those notes are added by WC itself. ATUM changes them in some cases (only when using Multi-Inventory or Product Levels) though.
The ATUM stock control works through our woocommerce website with no problems seeing as ATUM is controlling the stock on our site. When stock levels are decreased, as is the case in the attachment, that isn't going through the checkout on the website then the stock with ATUM isn't being deducted.
No matter whether an order goes through the checkout or you add it manually through the backend, the stock is changed when any order status is changed. So when changing to processing, on-hold or complete, reduces the stock. If you change back from any of these statuses to pending payment or canceled, the stock is restored back. This is how WC works and ATUM adapts itself to WC behavior (always).
I guess the best thing to do is wait for the ATUM POS add-on. We are a little resistant to purchasing any licenses at this stage if we can't control the stock company wide.
If you want to test the ATUM POS, you can request testing our ATUM Mobile App beta. We wouldn't recommend using it on a live environment yet though. If you want to test the beta, just open a private ticket and ask for access.
I know the next question is a 'how long is a piece of string' question but any ideas how long it will be until ATUM POS add-ons are available? Since starting a woocommerce website we have wasted so much time trying to control stock - its been a nightmare.
The App is almost complete and we hope to release it very soon.
