“Rework Is The Cost That Never Shows Up On The Quote.”
The invoice stays the same. The labour doubles.
A job quoted at 40% gross margin becomes a 10% job the moment you send someone back to fix it.
8 - 15% of total labour hours in the average service business go on rework, callbacks, and fixing mistakes. On a $1.5m business that's $120k - $225k of revenue being delivered twice.
Most owners know rework is a problem. Few have measured it.
The cause is almost always one of three things:
Unclear scope at the start.
No quality check before completion.
Staff not trained to the required standard.
A one-page job brief. A completion checklist. A proper onboarding standard. Basic disciplines most businesses skip because they're busy.
What does rework actually cost your business each month?
