3. From the Account Type ▼ dropdown, select Expenses.
4. From the Detail Type, select Bad debts.
5. Click Save and Close.
   
   

Create a bad debt item:

1. Go to Settings ⚙, select Products and Services.
2. At the upper right, click New, and then Non-inventory.
3. In the Name field, enter “Bad debts.”
4. From the Income account ▼ drop-down, select Bad debts.
