How I can run a report for quantity been purchased of each item/SKU from day one

Thank you, this is the only time that QB solve a problem

Good day, @hans_axiom.

Yes, In QuickBooks Online (QBO), you can view the product quantities from the purchase order report.

I'm happy to walk you through the process. Please refer to the steps below:

1. Go to Reports.
2. Navigate from the find report by name in the upper right corner.
3. Type in the Open Purchase Order Detail report on the search bar.
4. Filter the report period to All Dates.
5. Once done, click on Run Report.

Moreover, you can generate a report for open purchase orders. Nonetheless, once a purchase order is converted to a bill, there isn't an available option to pull up that report. Otherwise, you can still check your QTY manually once it is converted to a bill. Here's how you can do it:

1. Go to Expenses menu.
2. Click on Expenses.
3. On the All Transactions section, click on the dropdown.
4. Choose the desired Purchase Order to see the quantities.
5. Once there, click on Item details.
