Welcome to the Community space, mirl.

Creating a Product Stock Ageing Summary report, like A/R, is unavailable. I recognize how it would help understand how long they have been in stock, so let me help you request this functionality from our developers.

In QuickBooks Online, you can review your stock by running the Inventory Valuation Summary, Inventory Valuation Detail, and Physical Inventory Worksheet. On the other hand, the Aging Detail and Summary reports are designed for Accounts Receivable (A/R) and Accounts Payable (A/P). In this case, the system does not currently offer an automated feature to filter and categorize inventory items based on their duration in storage.

I understand that this report helps identify aging stock and maintain healthier inventory levels. Therefore, I recommend submitting a request for additional reporting or customization options. Follow the steps below:

1. Go to the Gear icon at the top.
2. Under the Profile column, select Feedback.
3. Share your suggestion regarding the missing notification, then click Next.

Keep an eye on your suggestions on this website and visit our blog for recent developments.

As a workaround, analyze product activity manually by running the Sales by Product/Service Detail report and then filtering its Report period. Alternatively, you can search for third-party tools in the Apps menu that help you manage stock efficiently.
