There are 3 types of tasks in Paymo:
By default, tasks inherit their billing type based on the project. This means that:
NOTE: You can change the billing type of tasks only for Time and materials projects. This means you can have a time and materials project and have time-based, flat rate, and non-billable tasks in the same project.
In order to have flat rate tasks, you need to: set the project to Time and materials β Set the billing priority to tasks β Change the task billing type to flat rate.
To change the task type you can either hover over the task in List β Full task details and change the billing type or do it from the billing type columns inside the task Table View.
