The text agent that
actually books the job.
Every missed call gets a text back in under 60 seconds — in your voice, with your prices, on your number. Qualifies, scopes, schedules. You get a booked job, not a “new lead” to chase.
What it does
What it actually does.
Two-way conversation
Not a script. Qualifies, scopes, and schedules — in your voice with your prices.
Your price book
Returns real ranges from your real numbers — not guesses or stock SaaS averages.
Calendar handoff
Books into Jobber, Housecall, ServiceTitan, Tradify, ServiceM8, or a plain .ics.
After-hours coverage
24/7. Knows when you're booked and offers the next available slot, not a vague callback.
Knowledge base
Service area, brand list, FAQs, ETA windows, deposit policy — built by hand with you.
Spam filter
Drops robo-text and known spam shortcodes before they hit your eyes.
Transcript audit
Every threading session reviewable. Adjust voice, tone, or scoping anytime.

The SMS agent runs while you're under a sink. By the time you check your phone, the customer's already on your calendar.

What it won't doThe honest list
The honest list
of limits.
Every AI receptionist company sells you on what their bot can do. Most won't tell you what it can't. We'll save you the discovery — here's what this agent doesn't do, so you can decide if it's right for you.
- Cannot dispatch a techBS-01 books — you (or Dispatch) routes. Dispatch routing is on the roadmap, not in the agent.
- Cannot pull permitsAnything that requires a person, a license, or a signature stays with you.
- Will not quote outside your bookIf a job falls outside the ranges you trained it on, the agent asks you and waits to send the reply.
FAQWhat you'd
What you'd
actually ask.
Does the customer know they're texting an AI?
We don't pretend. Every BuildStack thread is branded to your business — but if asked, the agent says it's an AI helping the front desk. Most customers don't care; they care that someone replied fast. Behind the scenes it's all your tone, your prices, your voice.
What happens to the conversation after the booking?
The thread is logged in your unified inbox with the booking, the price quoted, and any context. Your CRM syncs the contact and the appointment. If the customer texts back later, BS-01 picks up where it left off.
What does “trained on your voice” actually mean?
During onboarding we collect 20+ examples of how you actually reply to customers — formal vs casual, emoji or no, your typical sign-off, the small phrases you use. We tune the agent to match.
What if I want the agent to stop replying?
Flip a switch in your dashboard. The agent goes silent on that thread and pings you. You can also set rules — e.g., always escalate quotes over $5,000.
