An AI agent re-engages past customers and revives open quotes over WhatsApp, books visits, and logs it all in your CRM. ## The work you already did is worth more than you think Most plumbers spend their lives chasing new customers. Ads, referrals, the number on the side of the truck. But there's a gold mine almost nobody touches: the people you already fixed something for. They already know you, already paid you, already trusted you. And yet, once the job's done, the contact goes cold and disappears. It happens constantly. You quote a water heater replacement, the customer says "let me think about it," and you never follow up. You clear a drain, and six months later that same house has another problem, but they call a different plumber because they forgot your number. The work was right there. Nobody picked it up. At Catalizadora we build an AI agent that handles exactly that for you: it follows up on every open quote and re-engages the customers you've already served, all over WhatsApp, without you lifting a finger. ## The two money leaks nobody sees ### Quotes left hanging Every "let me check with my wife" is a half-closed job. If nobody follows up in two or three days, that customer goes with whoever did follow up. The agent does it for you: a few days later it sends a natural message, recalls the quote, clears the doubt that stalled the decision, and if the customer says yes, books the visit on the spot. ### Customers who were served and went cold A water heater lasts a certain time. A boiler needs maintenance. A house with old pipes will spring another leak. You know this, but you have no way to remember every customer and when it's worth reaching back out. The agent does. It schedules smart re-engagements: at the right months it messages that customer, offers the inspection or maintenance, and puts you back in front of them right when they need you. ## Manual follow-up vs. automated follow-up Let's compare what happens today with what happens with an agent. **Today, by hand:** you finish the job, jot the number on a scrap of paper or in your phone's notes, think "I'll text them later," and never do because you're already on the next repair. Out of 30 customers served in a month, you actually follow up with two or three. The rest go cold. **With an agent:** all 30 land in your CRM. The agent follows up on open quotes within days and schedules each customer's re-engagement based on the type of service. It forgets no one. It never gets tired. It never has a bad day. If 6 of those 30 come back who would otherwise have been lost, that's 6 jobs out of thin air, without spending a dollar on advertising. That's the difference between leaning only on new customers and squeezing the value out of the ones you already have. Winning a new customer costs money: ads, time, competing on price. Selling again to one who already trusted you costs almost nothing, because the trust is already there. All that's missing is someone to remember them at the right moment. Think of it this way: over the years you've built up dozens or hundreds of customers who already paid you. That list is an asset, not a scrap of paper forgotten in the glovebox. An agent turns it into recurring work. ## How it works, no headaches Follow-up and re-engagement aren't a spam blast. They're WhatsApp conversations, one at a time, in your business's voice: - After a quote with no reply, the agent picks it back up naturally and handles the objection. - After a service, it schedules the maintenance reminder at the right time. - When the customer replies with intent to buy, it **books the visit and sends the payment link** if a deposit applies. - Everything stays in your CRM, so you see who's warm, who booked, and who needs you to step in. You don't write the messages or keep a list. The system sets the pace and only flags you when there's a job ready to close. It's like having an assistant dedicated to your book of business, but without hiring anyone, without payroll, and without ever letting a customer slip through. ## What it costs and what's yours At Catalizadora we follow a method called MAGIA: Mapping, Architecture, Generation, Implementation, and Autonomy. We map how you follow up today, build the agent around your services and timing, and leave it running on its own. The entry package, **MAGIA Solo**, costs **$4,500 USD** and ships in **15 days**, with the WhatsApp agent, the CRM, and your online presence. If you run multiple crews or locations, **MAGIA Core** ($15,000) and **Forge** ($20,000, 12 weeks) scale the same thing. And the part that matters: **the code, the data, and the infrastructure are 100% yours**. No retainers, no locked licenses. Operations run as pass-through, roughly **$200 to $400 USD a month**, with no markup from us. The system is yours; we build it and hand it over. ## The core idea Winning a new customer costs money. Selling again to one who already knows you is almost free, if someone remembers them. That someone can be an agent that forgets no one and works your book of business while you're out on the road.

It's when the agent reaches back out over WhatsApp to customers you've already served, at the right time for each service, to offer maintenance or revive a pending quote, recovering jobs without paying for advertising. ### Does the agent follow up on quotes that didn't close? Yes. A few days after a quote with no reply, the agent picks the conversation back up naturally, handles the objection that stalled the decision, and if the customer agrees, books the visit and sends the payment link when a deposit applies. ### Won't this feel like spam to my customers? No. These aren't mass blasts, they're one-on-one conversations in your business's voice, sent at the right moment. When a conversation needs your hands, the agent passes it to you. ### How much does it cost and who owns the system? MAGIA Solo costs $4,500 USD and ships in 15 days. The code, data, and infrastructure are 100% yours, with no retainers or locked licenses; you only pay pass-through operations of roughly $200 to $400 USD a month. ### How do I try it?
