# 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%. ![](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/how-do-i-fix-the-error-a-non-zero-invoice-cannot-be-assigned-to-a-non-managed-technician-image-vamqgnn6.jpg?sv=2026-02-06&spr=https&st=2026-10-31T02%3A38%3A42Z&se=2026-10-31T03%3A38%3A42Z&sr=c&sp=r&sig=F4K2U21wNS4%2BIBgafV8wBI6Pkg92o7bZm0jvWA6eWxA%3D)
4. When finished, click **Save**.

Split determines how much credit each technician is getting for the job. For example: If two technicians perform work on a job, the split could be an even 50%-50%, or it could be 75%-25% if the first technician did a bulk of the work. By default 100% of the technician split will go to the first technician assigned to the job.
