@brju2013 - Thanks for your patience while our engineers took a closer look. They saw the stock adjustments for the items you listed, but it is difficult for them to pin stock adjustments to their source. On 12-14 both the Small and Large "Mocha Turtle Neck Long Sleeve Tunic w/Lace Crochet." show a reduction in stock count by 2. If you go to https://squareup.com/dashboard/apps/my-apps you'll see that you have several apps other than BigCommerce, including an Ecwid store. These adjustments are most likely a result of the integrations. Can you please take a look at these other integrations?
I finally found the root of my issue, the same issue as what you have. It appears to be that if you are integrated with Big Commerce, all of your inventory management should be done in Big Commerce after initial import. What was happening to me was that inventory levels I was entering were not being sent to big Commerce. Moral of the story, maintain your stock levels in big Commerce, and you should be good.
I have been having this exact same issue. My problem with troubleshooting has been the inability to predict which items will change, so it has been hell trying to document this. I contacted support today on the phone with an example, and they said they would escalate. I doubt these are one off issues, and it was occurring before we integrated with Big Commerce as well. We do not even sell on Big Commerce yet. I wasn't given a ticket number, nor have I seen any confirmation emails about this yet.
Hey @scortinoandson, thanks for taking the time to contact our Support Team with an example. You should have received a case number. I'll reach out to the email address that's tied to your account. If you could reply to it with any additional details that you went over via phone as well as mention the item that was causing the trouble — we'll make sure nothing slips by. Thanks again for your help with this!
