Is there a way I can search for a particular product on multiple uploaded supplier invoices, to see how many units I've purchased in total over multiple invoices?

Yes, it is possible to determine if a product was purchased multiple times across different supplier invoices. I'd be happy to help you find that information, Loren.

To start, you can run the Purchases by Product/Service Detail report. Allow me to walk you through the steps:

1. Go to the Reports menu.
2. Type in Purchases by Product/Service Detail in the Search bar.

Then, customise the report so the information is sorted out and grouped by product. Let me share these articles as your guide:

Once you have the report, review it to identify which items were present across multiple bills or supplier invoices.

In addition, I'd be happy to provide some articles that offer further guidance on finding supplier and product-related information in QuickBooks Online:
