Real ROI numbers, recovered emergency jobs, and a month-to-month cost comparison. ## The call you missed at 11 p.m. A customer has a burst pipe on a Sunday at midnight. They call you. You're asleep. They call the next plumber on the list. That emergency job, the most profitable one of the month, goes to someone else. This isn't a phone problem. It's a coverage problem. A plumber can't answer a call while lying under a sink with grease on both hands. And at the exact hour a leak is most urgent, almost nobody picks up. This is where the AI agent comes in. A WhatsApp bot that answers in seconds, at any hour, in your business's voice: it asks what broke, where, how long ago, sends a base quote, books the visit, and saves the contact so you can follow up. It doesn't sleep, doesn't get sick, doesn't go to lunch. The question every independent plumber and plumbing company asks is blunt: how much does that cost compared to hiring a person to answer the phone? Let's look at the numbers. ## What a person who answers the phone costs Take a real case: a plumbing company that wants to stop missing calls. The traditional option is to hire someone for reception and scheduling. The cost is not just the wage. - **Monthly salary**: an administrative role in your city. - **Benefits and payroll taxes**: add 20% to 40% on top of the wage, depending on the country. - **Hours**: one person covers 8 hours. Leaks don't respect business hours. To cover nights and weekends you need two or three people, or an on-call service. - **Ramp-up and turnover**: the first weeks aren't fully productive, and when they leave, you start over. Even with one part-time hire, the first year rarely comes in under several thousand dollars. And you still don't cover Sunday at 2 a.m., which is exactly when the well-paid emergency comes in. ## What the AI agent costs At Catalizadora we build the agent as part of a complete system. It's a one-time investment, not a payroll line that repeats every month. - **MAGIA Solo**: 4,500 USD, delivered in 15 days. Includes the WhatsApp agent, the website, your search visibility, and the CRM where every conversation lands. - **Operations**: 200 to 400 USD per month for hosting and usage, pass-through, with no markup from us. That's the cost of keeping the system running, nothing more. - **No retainers, no locked-in licenses**: you pay for the build once. We don't charge you a monthly fee to use your own system. Compare it month to month after the first year: a receptionist still costs their full salary plus taxes, every month, forever. The agent costs the 200 to 400 in operations, and it works day and night. ### The simple math Say you lose four emergencies a month because no one answers. If each emergency leaves even a modest profit, those four recovered calls pay for the agent's operating cost several times over. The full 4,500 system pays for itself in a few months with the jobs that used to go to the competition. It's not magic. It's coverage. The agent doesn't fix the leak, you do that. The agent makes sure the call isn't lost and the customer is booked before they call someone else. And there's an effect the table doesn't show: response speed. The customer with water running across the floor doesn't shop around, they hire the first plumber who answers and gives them a time. When your business replies in seconds at any hour, you win jobs you never even knew were in play, because they were decided in the two minutes it used to take you to glance at your phone. ## A person and an agent don't do the same job Let's be honest. A good receptionist improvises, calms an angry customer, recognizes a regular. The agent doesn't replace the human touch on a job site. What the agent does better than any person is never fail at the repetitive part: always answer, at the same speed, with the same correct information, no matter the hour or the mood of the day. It qualifies whether it's an emergency or a quote, asks for the address, proposes a time, and logs everything. Many companies end up using both: the agent filters and books 80% of the simple cases, and the person focuses on big accounts and field work. Without anyone glued to the phone. ## What the system includes, beyond the bot The agent alone already recovers calls. But at Catalizadora we deliver it inside a system so the whole business grows: - **Your own website** with your services, ready for people to find you. - **Visibility** through a proprietary technical layer that helps you show up when someone searches for a plumber in your area. - **CRM** where every conversation is saved: who called, what they needed, whether it was booked. So you follow up and nobody slips through. The code, the data, and the infrastructure are 100% yours. If you decide tomorrow to run it all on your own, you take it with you. We don't lock you in. ## The next step If you're missing calls, you're already paying the cost. You just pay it in jobs that go elsewhere, not in a visible invoice.
