Total Mechanical has been building trust across the Pacific Northwest for more than four decades. Founded in 1979, the company has earned a reputation for handling complex builds, renovations, and high-performance systems in mission-critical environments. Their work spans hospitals, schools, light industrial facilities, and public institutions.

When Total Mechanical acquired a plumbing company in Astoria, Oregon, leadership saw an opportunity to grow their residential and service business.. But the expansion raised a critical challenge: how could they scale a high-volume service division while keeping it connected to their established construction operations?

The Growing Pains of Expansion

Vista had long served as Total Mechanical’s ERP backbone. But as VP of Operations Ben Carlson put it, Vista alone couldn’t support modern field operations:

No way to accept credit card payments or offer flexible financing in the field.
No mobile-friendly way for technicians to track timecards and job costs.
No service workflows designed for high-volume residential work.

ServiceTitan offered exactly what technicians needed. But without an integration, Astoria would either need its own accounting system or a clunky patchwork of manual workarounds. That was a non-starter.

“Our only way to give [our] techs modern tools like field payments and credit options was to adopt ServiceTitan. But we couldn’t afford to run two sets of books. Agave was the key to making it work.”

Agave as the Connective Tissue

Agave’s integration between ServiceTitan and Vista became the connective tissue that allowed Total Mechanical to modernize service operations while keeping the business unified.

Single payroll run. Technicians track their hours in ServiceTitan, Agave moves those timecards into Vista, and payroll is processed once for the whole company.
Right tool for the job. The Astoria service team works entirely in ServiceTitan, while headquarters remains in Vista. Agave ties them together, letting each team stay in the platform that fits their workflows.
AR flexibility. Payments can be recorded in either ServiceTitan or Vista, and Agave ensures both systems stay aligned.
Lower license costs. Because more staff can stay in ServiceTitan, Total Mechanical avoids adding several extra Vista licenses—savings that help offset the cost of integration.

Fast Setup, Trusted Support

Implementation of Agave was fast and smooth. Ben credits Agave’s co-founder, John Zucchi, for making all the difference.

“John was extremely responsive and knowledgeable in both systems. He didn’t just tell us what to do — he explained why things worked the way they did. That made it easy to troubleshoot and get to the right solution quickly.”

What impressed the team most was Agave’s expertise across both ServiceTitan and Vista. That dual knowledge proved critical for troubleshooting and gave leadership confidence that the integration would hold up in real-world use.

Growing Without Adding Complexity

As Total Mechanical looks to scale its service division from 8 to 30 techs, our integration is proving invaluable.

‍

“Agave enables them to stitch on best-in-class systems like ServiceTitan while keeping all financials tied back to Vista.“Agave is easy to set up, it runs itself in the background, and it just works. It lets us grow without adding complexity.”
