How do I fix the error "A non-zero invoice cannot be assigned to a non-managed technician"?

Problem

I can't edit the invoice due to the error message A non-zero invoice cannot be assigned to a non-managed technician.

Solution

Set technician splits

This error message occurs when the technician assigned to the job is unmanaged or deactivated. To resolve the issue:

1. Open the invoice for the job.

2. In the side menu, click Adjust Splits.

3. Change the splits so that the managed and active technicians have 100% of the splits, and the non-managed or deactivated technician has 0%. 

4. When finished, click Save.
