There may be occasions where the daily rate is automatically set using the 20-28 units rule, but you would rather use unit rates. It is important to note that this choice should be written into the client's plan.
In order to force unit rates, the first step is to setup the client to be permitted to use this option. This is done in Client Information:
If this is checked, then there will be an option force unit rates when documenting the daily attendance. To use this option, click the client in Attendance and check the 'Unit Rate Billing' checkbox.
By doing so, unit rates will be used even if the number of units is 20-28.
