After-hours call to a plumbing company
Voice call
Agent actionTwilio
Call came in through Twilio at 9:04 p.m., outside office hours. Picked up on the second ring.
Agent
Thanks for calling. You've reached the after-hours line for Example Plumbing. The office is open 8 to 5, Monday through Friday. What's going on?
Caller
A pipe burst under my kitchen sink and there's water everywhere. I need someone tonight.
Agent
Let's get someone out. First, do you know where your main shutoff valve is? Turning it off stops the water while we get a plumber on the way.
Caller
Yeah, I just shut it off. It's dripping now, not spraying.
Agent
Good. What's the address, and is this a house or an apartment?
Caller
It's a house. 418 Maple Court, out on the east side.
Agent actionServiceTitan
Looked up 418 Maple Court in ServiceTitan: no existing customer record. The address is inside the service area.
Agent
You're in our service area. Can I get your name and the best number to reach you on tonight?
Caller
Dana Whitfield. This number is fine.
Agent actionServiceTitan
Created a customer record for Dana Whitfield and an emergency job at 418 Maple Court in ServiceTitan, tagged burst supply line under the kitchen sink, water off at the main.
Agent
Done. I've booked an emergency visit. I'm paging the on-call plumber now. There is an after-hours dispatch fee, which the plumber confirms with you before any work starts. Can I stay on the line while I connect you?
Caller
Yes please.
Agent actionTwilio
Warm transfer through Twilio to the on-call plumber, Rob, with the summary: burst supply line under the kitchen sink, water off at the main, 418 Maple Court, Dana Whitfield.
Agent
Rob is on the line now. Rob, I've got Dana at 418 Maple Court with a burst supply line under the kitchen sink; the main is shut off. Dana, you're all set, I'll drop off here.
Scripted demo. Names and numbers are made up.
Seven modules, each wired into the systems you already run, each shipped into production and measured against a written target.
An AI voice agent answers your phones 24/7, qualifies the caller, and books the job into ServiceTitan, Jobber, or Housecall Pro. Live in 3 to 4 weeks.
Quote automation pulls the job from intake, applies your pricing matrix, and sends a branded quote in about 4 hours instead of 2 to 3 days. Live in 4 weeks.
A dispatcher copilot on McLeod and Samsara drafts driver and route assignments, re-routes live. Planning time down 50% at a 200-route 3PL. Live in 6 to 8 weeks.
Review reactivation asks for the review 2 hours after the job, catches low scores before they go public, and rebooks past customers by SMS. Live in 3 weeks.
An AI chatbot that answers from your own content, cites the page it came from, and hands off to a booking, a call, or a text. The bot on this site is the demo.
We add AI to the software you already run: retrieval over your own data, agents inside your existing stack, and the architecture that keeps it maintainable.
AI consulting services for $5M to $50M service and manufacturing businesses: a fractional AI lead 2 days a week for 90 days, a roadmap, the first system live.

Voice agents, quote automation, dispatcher copilots, review reactivation, chatbots, AI added to the apps you already run, and AI consulting with fractional AI leadership. Every deployment carries a written ROI commitment.
Web platforms, mobile apps, websites for service businesses, and CRM and CMS integrations. An engineering practice since 2014 with 200+ shipped projects; we build the systems our AI runs on.
We start with your operation, not our product. In a 30-minute working session and the diagnosis that follows, we audit your call flow, quoting process, dispatch workflow, and revenue leaks, and talk to your CSRs, dispatchers, and techs. You get a revenue leak map and an ROI projection in 1 to 2 weeks. The written commitment: we will tell you not to hire us if projected year-one ROI is under 3x.

The agents and automations are what we deploy. Behind them are 40 apps and websites Plainbuilt designed and built full stack: the proof that the software side is in-house too.
We start with your operation, not our product. In a 30-minute working session and the diagnosis that follows, we audit your call flow, quoting process, dispatch workflow, and revenue leaks, and talk to your CSRs, dispatchers, and techs. You get a revenue leak map and an ROI projection in 1 to 2 weeks. The written commitment: we will tell you not to hire us if projected year-one ROI is under 3x.
We design the system, pick the modules, name the custom work, and set a measurable target for each deployment. You get a roadmap with timelines, costs, and expected outcomes in 1 to 2 weeks. The written commitment: the roadmap document is yours whether or not we proceed together.
We build and ship into your live operation, wired into the stack you already run (ServiceTitan, McLeod, Jobber, whatever it is), and test in production with real traffic. 3 to 8 weeks depending on scope. The written commitment: a kill switch on every deployment, and production-grade only, nothing that works only in a demo.
We track every deployed workflow against the projection in the build plan at 30, 60, and 90 days, on the numbers that hit your P&L: lead capture rate, quote turnaround, dispatch efficiency, cost per acquisition. What works gets expanded; ongoing support is a flat monthly fee with SLAs. The written commitment: if a workflow underperforms its projection by 20% or more, we redesign on our dime.
Leave your number and a person from Plainbuilt calls you back to talk through what is leaking revenue in your business. The voice agent demo runs on the site once its phone line is switched on.

Most AI agencies sell you a pilot that lives on a shelf. We ship production systems with a written commitment to measurable ROI.

Plainbuilt does AI automation and custom software for service and operations businesses: contractors, field services, logistics, healthcare, real estate, and manufacturing, running $5M to $50M in revenue. We ship voice agents, quote automation, dispatcher copilots, and review reactivation wired into ServiceTitan, Jobber, McLeod, Samsara, and HubSpot, and we build the web platforms, mobile apps, and integrations they run on. Each module is live in production in 3 to 8 weeks, not a pilot deck.
Service and operations businesses doing $5M to $50M a year whose work depends on phone, email, dispatch, or quoting. Typical clients are contractors on ServiceTitan or Jobber, field service operators on Workiz or Housecall Pro, 3PL and logistics shops on McLeod or Samsara, and medical practices on Athenahealth or DrChrono. If your team is bottlenecked by a person or a phone, you fit.
Most modules ship into production in 3 to 8 weeks. A voice agent wired into ServiceTitan typically goes live in 3 to 4 weeks. Quote automation runs 4 weeks. A dispatcher copilot on McLeod and Samsara runs 6 to 8 weeks because of the route logic. We commit to the timeline in writing in the build plan.
It depends on which modules you deploy, the integrations involved, and how much is custom to your operation. Most clients start with a single module and expand once it proves out. Every engagement comes with a written ROI projection; if first-year ROI looks under 3x, we tell you not to hire us. You'll get a clear, itemized quote in the working session.
Agencies build what you ask for. Plainbuilt works out what you should build first, through a paid diagnostic that produces a written revenue-leak map, then ships into production with a kill switch on every deployment. If a workflow underperforms its written projection by 20% or more, we redesign on our dime. No vanity metrics, no pilots that live on a shelf.
Plainbuilt is headquartered in Evansville, Indiana, with an engineering center in India. We serve the United States first; clients are also in the United Arab Emirates and the Kingdom of Saudi Arabia. Engagements are remote-first, with on-site availability where needed.
