What FieldStack delivers

Three systems. One price. Zero office staff.

AI Phone Agent

Answers every call, 24/7. Books appointments, takes payments, handles questions — no hold, no voicemail, no missed opportunity. Voice AI has crossed human-quality. Your customers won't know the difference.

Auto Follow-Up

Quotes, review requests, maintenance reminders, rebooking campaigns — all automated. GoHighLevel powers the nurture sequences so nothing falls through the cracks between jobs.

Dispatch Optimization

AI routes your techs to cut drive time by 25%. Smarter scheduling means more jobs per day, less fuel burned, and customers who get the right response time.

How it works

From zero to fully operational in 14 days.

01

Pick your niche

Start with HVAC in your city. One industry, one market. Build a playbook you can copy everywhere else.

02

Onboard one pilot client

Give them the AI phone agent free for 30 days. Record every call. Show them exactly how much revenue you booked that would have been missed.

03

Turn it into a case study

One real recording, one real number ($ booked) = your entire sales deck. Door-knock 20 shops with it. Close 2-3 at $1.5k/mo.

04

Scale with a VA

Hire a part-time VA to handle onboarding. You only do sales. At 7 clients you're at $10.5k/mo — and you've built a repeatable machine.

Why 2026 is the year
this works.

Voice AI got good.

Customers stopped hanging up. In 2023, AI voice agents had a 60% hang-up rate. Today it's under 10%. The technology crossed the threshold.

Small shops can't hire.

The labor market for admin staff is gone. A 4-truck HVAC company can't justify a $45k/year receptionist. But they can justify $1.5k/month for AI that never sleeps.

One saved job pays for the month.

A single missed call can be a $300–$800 job. One AI-booked job per month covers FieldStack's entire subscription cost. The ROI is immediate and provable.

Small home services companies print cash — but they leak it through the cracks of bad systems. FieldStack closes the gaps. One AI-powered stack that runs the office so the crew can run the jobs.
