Hi there hea,

I can help you add a new expense category to the Chart of Accounts. The steps are simple and easy to follow. Here's how:

1. Click Accounting on the left panel.
2. Click the New button at the top right.
3. Select the Category Type (Expenses or Other Expenses).
4. Select the Detail Type (see the description below to help you select the right type).
5. Enter the Name.
6. Description is optional.
7. Click Save and Close.

I've added screenshots for you to see the steps.
