Hello there, @ckelitepromos.

Let me provide some information about the error you encounter.

This happens if you selected an asset account as a payment account. However, make sure to select the correct bank account in creating an expense. Let me show you how to do it.

1. From the left menu, click the + New icon.
2. Select Expense.
3. In the Payment account section, select your bank account.
4. Under Category, click Owner's Equity.
5. Enter the amount.
6. Click Save and close.
