# Add a technician to a chargeable material on an invoice

## Overview

Chargeable materials are material items billed as their own line on an invoice. You can assign a technician to a chargeable material directly on the invoice so the right person is credited with that item. This keeps billing and technician tracking accurate, which matters for commission and performance pay tied to invoice items.
