A done-for-you AI automation agency for service businesses

A good AI automation agency for a service business should build three things first, in this order: catch every missed and after-hours call, follow up on every estimate that went quiet, and send the owner one honest report each morning. Those three sit closest to revenue and inside software you already run. If an agency pitches a chatbot for your website or a forty-step "AI transformation" before those, keep looking.

Most pages ranking for "AI automation agency" are written for people who want to start one. This one is for the owner hiring one.

What a done-for-you AI automation agency actually does

A done-for-you agency builds the automations and agents for you, connects them to your tools, and (if you pay for it) keeps them running. You don't learn the software. You approve what goes out and tell them when something is wrong.

For a home-service company the tools are usually a field service platform (ServiceTitan, Jobber, Housecall Pro), a phone system, a CRM or GoHighLevel for texting, QuickBooks, and Google Business Profile. The agency's job is to make those systems catch the work that falls between them. It shouldn't be selling you a new platform to replace them.

What to build first, and why in this order

1. Missed and after-hours calls

The phone is where service businesses lose the most work they already paid to get. Invoca analyzed home-services calls across its customer base and found only 52% of callers reach a person, with answer rates ranging from 32% to 74% depending on the trade. The same report found 55% of businesses don't ask the lead to book the job on the call.

What the build should do: every call that ends with no job created gets matched against your FSM within the hour. If there's no booking, a callback text is drafted for the CSR, or sent automatically after hours if you allow that. The owner sees the count every morning.

2. Estimate follow-up

The second leak is quiet. A full system replacement quote goes out, the customer says they'll think about it, and nobody calls on day four because the comfort advisor is running new leads.

What the build should do: watch estimates by status and age, draft a follow-up in your company's voice on the days you choose, log it back to the customer record, and hand the warm replies to a person. It shouldn't discount on its own. That's how you train customers to wait for a better price.

3. Owner reporting

Once the first two run, the owner needs to know they're working. One message each morning: calls missed and recovered, estimates followed up, jobs booked, invoices open. Pulled from the FSM, phone system and QuickBooks, not typed by the office manager.

This third build is also how you keep the agency honest. If the report shows the callback agent drafted nothing for a week, something broke.

What to put in the scope of work

Before you sign, ask for each build to be written up on one page with these lines. A real agency can fill them in during a first call.

Line in the scope	What a good answer looks like
Trigger	"A call ends unanswered and no job exists for that number within 60 minutes"
Systems read and written	Named: "Twilio call log, ServiceTitan customers and jobs, read only"
What it does alone	"Drafts the text and logs it"
What a person approves	"The CSR sends it, or edits it"
How you'll know it works	A number you can check each week
Who fixes it when it breaks	A name and a response time
Who owns the build	You keep the accounts, credentials and workflows if you leave

If the agency can't name the systems and fields, they haven't looked at your stack yet. That's what an audit is for.

What agencies charge

There's no standard price, and you should be skeptical of anyone who quotes one before seeing your software. For reference, agencies publish ranges like these on their own sites. JADA Squad lists a single-flow automation build at $3,000 to $15,000 and ongoing managed operations at $500 to $5,000 or more per month. StratumIQ says project work ranges from $5,000 for simple workflows to $100,000 or more for enterprise work, with subscriptions at $1,000 to $5,000 monthly.

Those are their numbers, not ours. Cortex prices after the audit, because cost depends on which systems you run and whether their APIs let us in.

Why hire an agency at all

You could build some of this yourself with Zapier and a ChatGPT account. For a single fixed step, you probably should.

Where owners get stuck is the second and third build, and the upkeep. MIT's NANDA project interviewed 52 organizations for its 2025 report and found AI tools built with outside partners reached deployment about 67% of the time, compared with about 33% for internal builds. That sample was large companies and the authors say it may not represent the wider market, but the pattern matches what we see: the hard part is connecting systems and keeping the connection alive.

Small companies are also further behind. The Census Bureau reported that fewer than 20% of firms with four or fewer employees use AI, against 37% of firms with 250 or more. Most trades owners don't have a spare person to own this.

Red flags when hiring an AI automation agency

In September 2024 the FTC announced Operation AI Comply, a sweep against five companies accused of using AI claims to deceive customers, three of them selling online business opportunities. Its chair put it simply: there is no AI exemption from the laws on the books. Gartner, meanwhile, estimates only about 130 of the thousands of agentic AI vendors are real and calls the rest "agent washing" (W.Media summarized the release).

Walk away from an agency that:

• Promises a revenue number or ROI before it has seen your call logs.
• Wants you to move off your field service software to use its platform.
• Can't tell you which person approves what the AI sends.
• Keeps the accounts in its own name, so leaving means starting over.
• Has no answer for "what happens when the API changes?"

Where Cortex fits

Cortex is a done-for-you implementation partner for service businesses. We build AI agents inside the software you already run, with a person approving anything that involves money or a promise, and we can keep them running after launch. Our implementation process runs audit, design, build, deploy, then optional management.

We don't have a stack of HVAC case studies to show you, and we won't pretend to. Our published case study is a private AI system running across four automotive businesses. The free AI Operations Audit is a 30-minute walk through your calls, estimates and reporting; you leave with a map of what to build first, whether or not you hire us.
