Most plumbers lose jobs without ever knowing it. The phone rings while you're under a sink, you can't answer, and that customer already called the next name on the list. The WhatsApp message at 9 p.m. sits on "read" until the next morning, by which point the customer already solved it with someone else. It's not a demand problem. It's a response problem.
At Catalizadora, the fix isn't hiring someone to answer the phone. It's an AI agent on WhatsApp that responds 24/7 in your business's voice, handles basic quotes, books the visit, and logs every conversation in your CRM. And we deliver it in 15 days for $4,500. This post walks you through exactly how that process works.
What the agent actually does
Before the how, the what. Your WhatsApp agent:
- Replies instantly to anyone who messages, day or middle of the night, leaving no one on "read."
- Understands the problem ("my drain is clogged," "the water heater is leaking") and responds with the right info for your business.
- Handles basic quotes and filters: it separates the customer who wants a real visit from the one just asking for a price.
- Books the appointment straight into your calendar, no back-and-forth about "what day works for you?"
- Sends the payment link when it applies and follows up on outstanding payments.
- Logs everything in your CRM: every customer, every conversation, every job, with no data entry on your end.
It's not a "press 1 for..." menu. It's a natural conversation that feels like talking to you.
How it's built in 15 days: the MAGIA method
We don't wing it. We follow a five-step method called MAGIA. Here's how it looks applied to your plumbing business.
Mapping
We start by understanding how you work today. What services you offer, how you quote, what people ask most, how you schedule, what tone you use with customers. If you clear drains, install water heaters, and fix leaks, the agent has to know it and respond the way you would.
Architecture
We design the conversation flow. What happens when someone writes "I have a leak," when the agent quotes on its own and when it hands the case to you, how it books, how it collects. This is where we lock in the voice: direct, approachable, professional —the one you'd use.
Generation
We build the agent. We connect WhatsApp, the calendar, payments, and the CRM. We load your services, your base prices, your answers. The agent starts sounding like your business.
Implementation
We test it with real scenarios: the urgent 11 p.m. customer, the one just asking for a price, the one who wants to book for Tuesday. We tune the tone and the answers until it feels right. Then we take it live.
Autonomy
We hand everything over and teach you how to use it. From there the agent works on its own, and you review a dashboard instead of chasing messages. The system is yours.
What it really costs, no fine print
The price is $4,500, one time. There's no agency retainer. There's no renewing license that locks you in.
After launch you only pay the real operating cost: hosting and WhatsApp messages, which run between $200 and $400 a month depending on your volume. You pay that directly to the provider, with no markup from us.
Let's compare. A part-time employee answering messages costs you several hundred to a couple thousand dollars a month, takes days off, gets sick, and doesn't work at 2 a.m. The agent costs a fraction, responds around the clock, and never calls out. The upfront investment pays for itself with the jobs you currently lose by not answering in time.
The part that matters most: you own it
The code, the data, and the infrastructure are 100% in your name. We're not renting you a service you depend on forever. We build you an asset. If you want to move it, change it, or expand it tomorrow, it's yours to do so.
That's what separates Catalizadora from a generic chatbot app: you don't rent, you own.
Three mistakes the agent saves you from
There are three money leaks almost every plumber has, and the agent closes all of them from day one.
The first is the customer who messages at night and gets no answer. Plumbing emergencies don't keep business hours: a leak at 11 p.m. is well-paid work, and if you don't respond, it walks. The agent answers at that hour in your voice and books the visit for the morning.
The second is the price-only shopper who eats your afternoon. Without a filter, you end up quoting over chat to people who were never going to hire you. The agent handles the basic quote and separates the curious from the real customer, so you only see the cases worth a visit.
The third is the follow-up you never do. The customer who said "let me think about it" and never heard from you again. The agent handles that follow-up for you, automatically, so it never slips through.
What you need to get started
Less than you'd think. You need a WhatsApp number for the business, clarity on your services and base prices, and 15 days. We do the heavy lifting with the MAGIA method. Your part is telling us how you work and checking that the agent sounds like you.
In two weeks you go from losing customers because you couldn't answer, to having an agent that responds, quotes, books, and collects while you're on the job.
The next step
If you lose jobs every month because you can't answer in time, those jobs pay for the agent on their own.
