How do I enter an expense into "Other Business Category"?

Thank you for reaching out to the QuickBooks Community, @arie2. I'm here to help you create an expense for your other business category.

There are two ways to create an expense. The first way is to create a check and create an expense directly. However, we'll ensure you have already created an account for your other business.

Follow these steps to create an account:

1. Go to Transactions and select Charts of Accounts.
2. Click New.
3. Fill up the necessary information.
4. Select Save and Close.

After creating the account, you can create expense transactions or write a check directly.

I have attached some articles that can help you manage your Transactions: 

• Enter and manage expenses in QuickBooks Online
• Add purchase orders to expenses, bills, or checks in QuickBooks Online
• Create and record checks in QuickBooks Online

I'll be here if you still have concerns about your Expense category. Have a great day!
