An AI agent runs upsell and cross-sell over WhatsApp, 24/7, in your brand's voice. Here's how. ## The money already sitting in your contact base Most agencies chase new leads non-stop while ignoring the gold they already have: buyers who showed interest and didn't close. The one who toured the two-bedroom and found it small. The one who wanted a specific area and ran out of options that month. The one who rented and will want to buy in a year. Those contacts are in your CRM, cold, because no one has time to go through them one by one. Getting a new lead on Meta costs money every single time. Reactivating one you already know costs a well-timed message. At Catalizadora we build AI agents that do that work on their own. The same agent that answers your leads on WhatsApp also runs upsell and cross-sell: it offers the higher-value property when the buyer can stretch, suggests alternatives when one doesn't fit, and wakes up the dormant contact when something that suits them finally lands. ## What upsell and cross-sell mean in real estate It's not selling for the sake of selling. It's offering the right thing at the right moment: ### Upsell: move the buyer to the higher-value property A lead asks about a $120,000 apartment. In the conversation, the agent picks up that their real budget is higher and that they value space. It presents the $150,000 option with an extra room and a better location, explaining why it fits what they asked for better. No pressure: it informs. Your human agent closes a bigger deal. ### Cross-sell: offer the complement or the alternative The apartment the lead wanted is sold, or didn't fit. Instead of losing them, the agent offers two similar properties in the same development or the same area. Or it cross-sells services: financing, a storage unit, extra parking. Each contact becomes several opportunities, not just one. ### Reactivation: wake up the dormant contact A property lands in your inventory that matches what a lead asked for three months ago. The agent messages them on WhatsApp: "Something just came up in the area you wanted, in your range. Want to see it?" Nobody had to remember that lead. The agent does it for everyone. ## Why an AI agent beats a CRM reminder Your CRM can remind you to call. The AI agent has the whole conversation. The difference in numbers: - **Without an agent:** a human reviews, at best, 20 or 30 old contacts a week, when there's time. Most of the base never gets touched again. - **With an agent:** the hundreds of contacts in your base get checked against every new property, every day, and the one who fits gets messaged instantly on WhatsApp, in their language and in your brand's voice. The agent doesn't get tired, doesn't forget, and doesn't have an off day. Every new property you upload automatically triggers messages to every contact who was waiting for something like it. And since the whole conversation lands in your CRM, your team sees who replied, what caught their interest, and who to call. The human steps in once the lead has raised their hand. ## We build it in 15 days, and it's 100% yours This agent is part of **MAGIA Solo: $4,500 USD, delivered in 15 days**.

The agent reads what the buyer said in the conversation —real budget, priorities, area— and matches it against your inventory. It only offers the higher-value property when it fits what the person wants and can afford. ### Can it reactivate old contacts already in my CRM? Yes. When you upload a new property, the agent matches it against your contact base and messages the ones who asked for something similar on WhatsApp, without anyone having to remember them. ### How much does it cost and how long until it's live? It's part of MAGIA Solo: $4,500 USD delivered in 15 days, a WhatsApp agent connected to your inventory and CRM. For larger operations, MAGIA Core is $15,000 and Forge is $20,000 over 12 weeks. ### Do I own the code and the data? 100%. Code, data, and infrastructure are in your name, with no retainers or locked-in licenses. The operation runs as pass-through, around $200-400 USD a month, with no markup from us. ### Does the agent pressure the buyer? No. It informs and suggests in your brand's voice. It presents higher-value options or alternatives only when they fit, and when the lead raises their hand, the case goes to your human agent with full context. --- Source: https://catalizadora.ai/blog/real-estate-agencies-automatic-upsell-cross-sell-ai-agent Author: Pablo Estrada — AI Catalyst, LLC (catalizadora.ai)
