- Create a recurring flat fee plan and define a setup cost.
- Edit the plan and change the Setup cost back to 0 and press the "Update Plan" button.
Error "should be atleast 0.01" is shown next to the Setup Cost field and plan can not be updated.
If you're looking to edit the plan's Set Up cost and update it to '0', you only need to delete the existing value and leave the field empty. You need not enter any value if you do not intend to charge any Set Up cost.
Hope this helps! :)
