How can I create custom expense categories?How can I maintain inventory within quickbooks?

Hi there, George. 

QuickBooks will create default expense categories in your Chart of Accounts. However, you can always create your own custom categories. Here’s how:

1. Go to Accounting from the left menu and choose Chart of Accounts.
2. Click the New tab at the top.
3. Select a Category /Account type (Expenses or Other Expenses).
4. Choose a Detail type. You can check the description below to help you decide the right one.
5. Type in the Name and click Save and Close.
