I am using manager desktop edition since 2022, I backed up a business in manager and transferred to another PC. when i import business, in inventory item section, qty on hand has been changed, i also update manager to latest version but issue is not resolve. what should i do?

Do you use Delivery note/ Goods receipt tab?

Quite a lot has changed. First make sure that you install the latest version of Manager from https://www.manager.io/download on your new PC. The carefully read https://www.manager.io/guides/inventory-items It will explain why @shahabb posted the question about delivery note and goods receipts tabs as these are required to know qty on hand.
