How can I run a report by expense category.? For instance, I want a listing of all expenses by vendor hitting hardware/software.

I'll be more than happy to guide you in running that report, cassandra-norman.
 

You can customize the Transaction List by Date report to view all the expenses from a particular category, grouped by vendor. Here's how to do it:

1. Go to the Reports menu.
2. Select Transaction List by Date.
3. Click the Group by drop-down menu, then choose Vendor.
4. Select the Customize button, then set the appropriate reporting date.
5. Under Rows/Columns, select the columns you want to add.
6. Under Filter, click the Transaction Type drop-down menu and then select Expense, Check, and Bill.
7. From the Distibution Account drop-down menu, select the appropriate expense category.
8. When you're done, hit Run report.
