Inventory Issue

We recently upgraded from Manager IO Desktop to the cloud-linked version, and we have encountered an issue with our inventory quantities. The quantities appear to be mismatched since the update, affecting our ability to track stock accurately.
In the summary, I can see the exact quantities, but when I check the inventory item table, negative quantities are showing
Could you please investigate this discrepancy and provide a resolution at your earliest convenience? Your prompt assistance would be greatly appreciated.

I have tried everything, but I’m still facing the same issue: the inventory items do not match the actual inventory on hand. Salespersons are unable to check the real-time stock from the inventory system, and only the finance team can view the accurate quantities by opening the summary. Because of this, sales staff constantly rely on finance to check item availability. I would appreciate your help in resolving this issue

Enable Qty Owned column in the Inventory Tab. Also check Qty to deliver and Qty to receive columns. There might be some invoices for which you havent created a delivery note/Goods receipt.
If there are no pending delivery or GRNs in actual then activate Qty to deliver column on Customers Tab and Qty to receive column on Suppliers Tab. From there you can create adjustment Delivery Notes and Goods Receipts which will match the Qty on hand to Qty owned.
