Quantity on hand in products and services list does not match Inventory Valuation Report

Let me route you to the appropriate support that can pull up your reports in a safe and secure manner, fionchow.

As much as I want to assist you here promptly, I'm unable to access your account to view the Quantity on hand in products and services list and Inventory Valuation report as this is a public forum and we value your security. With this, I'd recommend contacting our live support team to help you track the data discrepancy. They can also create a ticket if necessary regarding this issue.

Here's how you can contact them:
