Your patient already trusts you, but only bought the consult
A patient came in for her first appointment. She left happy, with her meal plan. And that's where the commercial relationship ended.
She didn't come back for follow-up. She never knew you had a three-month package. She didn't hear about your body composition measurements, or your program for her family. Not because she wasn't interested: nobody offered it at the right moment.
That patient was your easiest sale. She already trusted you. And you let her walk away with a single ticket.
At Catalizadora we build AI agents that do that job automatically: they offer the next step, the follow-up package, and the right add-on, inside the WhatsApp conversation, without you having to sell.
Why you're leaving money on the table
Selling to someone who already bought from you is far easier than landing a new patient. The new one costs you ads, time, and trust you still have to build. The one who's already been through your office has cleared all those barriers.
And yet most practices live off the first consult and nothing more. Why? Because doing upsell and cross-sell by hand is awkward and easy to forget. You're focused on the clinical plan, not on "hey, did you see I have a follow-up package?" You feel uncomfortable sounding salesy. And by the time you finally remember, three weeks have passed and the patient has gone cold.
An AI agent has none of those problems. It doesn't forget, it doesn't feel awkward, and it offers at the exact right moment.
Upsell vs. cross-sell: the difference
Let's be clear about the two moves, because the agent does both.
Upsell: the bigger package
This takes the patient from the one-off consult to the full package. Instead of charging for a follow-up appointment every time, you offer the three-month plan with follow-up included. Better for the patient (continuity, better results) and better for you (predictable income, higher ticket).
Cross-sell: the add-on
This offers something different that complements what they already have. The patient came in for weight loss; the agent offers your body composition measurement. The one who came for sports nutrition gets your supplementation plan. The mom who came in gets the family-plan proposal.
The agent knows what to offer because it knows each patient's context, which lives in your CRM.
How the agent does it, step by step
1. It knows each patient by their context
Every conversation and every patient detail lands in your CRM. The agent reads that context: why they came, what they bought, when their last appointment was. It doesn't offer blindly; it offers based on what that person actually needs.
2. It offers at the right moment
Timing is everything. The agent re-engages the patient when it makes sense: days before their plan runs out, after the first consult to propose follow-up, or when it detects a good moment for the add-on. All on WhatsApp, where the patient actually reads.
3. It sells in your practice's voice
It doesn't sound like an aggressive salesperson. It sounds like your practice taking care of the patient: "we saw your plan ends this week, shall we continue with follow-up?" That's service, not pressure.
4. It closes: books and charges
When the patient says yes, the agent books the appointment and sends the payment link in the same conversation. There's no friction between interest and purchase.
5. Everything is logged
Every offer, every reply, every sale lands in the CRM. You know which packages sell themselves and which don't. Your practice stops improvising and starts running on a system.
The concrete math
Let's use numbers. Say you see 40 first consults a month and your follow-up package costs three times a single consult.
Today, with no system, a minority of those patients move to the package, almost always the ones who ask for it themselves. The rest leave with a single consult.
With the agent offering follow-up to all 40, at the right moment and with each one's context, you convert a share that simply never got the offer before. Every patient who moves from a one-off consult to a package multiplies their value. And you didn't spend a cent more on ads: these are patients you already had.
Cross-sell stacks on top: body composition, family plan, supplementation. Each add-on is extra income from patients who already trust you.
What it costs and who owns it
At Catalizadora we work with no retainers and no locked-in licenses. The AI agent with upsell and cross-sell is built inside MAGIA Solo: $4,500 USD, delivered in 15 days. It includes the WhatsApp agent, the CRM, and the offer logic configured for your practice.
What matters:
- The code, the data, and the infrastructure are 100% yours. We don't rent you the agent. It's yours.
- Operation is pass-through, roughly $200 to $400 USD per month in hosting and tokens, with no markup from us.
If you grow and need something bigger (multiple locations, a team), MAGIA Core starts at $15,000 USD. For a practice that wants to squeeze the full value out of its current patients, MAGIA Solo is enough.
We use the MAGIA methodology: Mapping your catalog and your patients, Architecture of the agent, Generation, Implementation, and Autonomy.
The next step
The best way to understand the agent is to talk to one. Message our agent on WhatsApp: it'll reply in Catalizadora's voice, understand your case, and book you in, just like yours will do with your patients.

You already have patients who trust you. Stop selling to them just once.
