Compensation Structure – Commission‑Based Pay Plan

This position offers a commission‑based pay plan, giving you the opportunity to directly control your earnings. Under this structure, you will earn 30% of the total labor dollars you bill each month.

How it Works (Example):

• If you bill $30,000 in labor in a given month
• Your pay for that month will be 30% of that amount
• $30,000 × 30% = $9,000 in earnings

This pay plan rewards productivity, efficiency, and high‑quality work. The more labor you bill, the more you earn—there is no cap on your monthly income potential.
