From Invoice Overload to Time Saved: Service First Mechanical’s Story with 3rd Armor

When you’re reviewing hundreds of supplier invoices every month, it’s not just errors that drain profits—it’s time. For Service First Mechanical, a trusted plumbing company with years of expertise in both residential and commercial projects, invoice review was consuming entire workdays.

The Challenge: Hours Lost to Manual Reviews

Every month, Service First Mechanical faced 800–1,000 supplier invoices. The owner, Seth Watchinski, painstakingly reviewed each one line by line. While this uncovered billing errors worth thousands of dollars, it was exhausting, unsustainable, and left little time to focus on growing the business.

The Solution: Automated Invoice Monitoring

3rd Armor stepped in to eliminate the manual grind. Our system now audits every invoice automatically, catching discrepancies across all line items with unmatched accuracy. Instead of spending countless hours buried in paperwork, Service First Mechanical gained a streamlined, end-to-end process that flags errors before they hit the books.

And the results speak for themselves: the system identifies pricing errors on 15–20% of invoices every month—recovering missed savings and removing the stress of human oversight.

The Results: More Savings, More Time, More Focus

• 800–1,000 invoices audited automatically each month

• 15–20% of invoices flagged with pricing errors

• Owner freed from manual reviews to focus on running the business

As owner Seth Watchinski explains:“3rd Armor gave Service First Mechanical back valuable time. The system finds everything, and invoices no longer dominate the workday.”
