Hi @USV360.

You can run the Inventory Valuation Detail report to see the number of items purchased starting from day one. Then make sure to adjust the Report period to a starting date up to the recent date.

Here's how:

1. Click the Search icon on the top right.
2. Type Valuation in the Search box and then select Inventory Valuation Detail.
3. Change the Report period to Custom.
4. Adjust the dates.
5. Hit Run report.

You'll see the number of items purchased and the number of items being added. Also, it will show you there the remaining on-hand total of each item.

You can reference this article for more details: Run reports in QuickBooks Online. This covers how to run reports for specific accounts, print, email, and export reports.

Additionally, you can add other helpful columns to your reports. Just click the mini Gear icon of that specific report found on the upper right of it or Customize report data to see more specific details. From there, you can include some columns or remove them by checking and unchecking the boxes.

Feel free to comment if you have to need more assistance. I'm always here to help you out. Stay safe and more power to your business!
