Thanks so much for taking the time to respond @MariaSoledadG . My post however was about category details, not item details. So it looks like there might not be a way to run reports off category details - which I find pretty silly.
I appreciate you for trying the steps provided by my colleagues above, @typicole. Let me chime in and share other ways to run a report showing the category detail.
We can generate a Transaction Detail by Account report in your QBO account. Let me show you how:
- Select the Reports menu at the left panel.
- In the search field, look for Transaction Detail by Account.
- Click the Customize button.
- Choose the correct date and under Rows/Columns, click the Memo/Description option.
- Under Filter, tick the box next to Vendor.
- Once done, select the Run report button.
For visual reference, you can check out the screenshots below:


Additionally, I've attached some relevant articles you can utilize to help personalize and manage reports in QBO:
