An AI agent runs upsell and cross-sell on its own, without pressuring your team. ## The money already inside your firm An accounting firm has 200 clients. Most came in for a single service: an annual return, a registration, a one-off filing. They pay for it once and disappear until next year. And yet your firm does much more: monthly bookkeeping, payroll, tax planning, advisory for businesses, cleanups. Most of your clients have no idea you offer all of it. Not because they don't want it, but because nobody told them at the right moment. Selling more to someone who already bought from you is the most profitable thing there is. That client already trusts you, you already have their details, and you didn't pay for ads to win them. But upselling by hand takes time your team doesn't have, and it feels awkward: nobody wants to look like they are pushing services. At Catalizadora we build AI agents that run that upsell and cross-sell on their own, naturally, without anyone on your team chasing anybody. ## What the agent actually does The AI agent knows your service catalog and knows each client because every conversation lands in the CRM. With that, it works the base you already have: - **Spots the opportunity.** A client who only files an annual return but turns out to have employees is a natural fit for payroll. The agent notices. - **Starts the conversation at the right moment.** It doesn't bombard. When the client writes in for something else, or on key dates in the tax calendar, the agent brings up the service that fits. - **Explains in your brand's voice.** It answers questions, gives price ranges, handles objections, all in your firm's tone. - **Books or closes.** If the client is interested, the agent reserves the meeting or sends the payment link directly. - **Logs everything in the CRM.** Your team sees what was offered, to whom, and how each client responded. ## An example with numbers Say your firm bills on average **$300 USD a year per client** on its entry service. You have 200 clients. ### Without the agent Most stay on that single service. Maybe your team, when there is time, talks a few into something more. Say 10% move up. The rest of the catalog stays invisible. ### With the agent The agent works all 200 systematically and at the right time. If it only gets an extra 20% to take a second service (say monthly bookkeeping at $100 USD/month, $1,200 a year), that is 40 new clients on a recurring service. The math: - 40 clients x $1,200 a year = **$48,000 USD a year** in new recurring revenue. - Without hiring anyone. Without spending a cent on ads. We are not inventing those clients: they are already in your base. The agent simply activates the value you already have and nobody is charging for. ### Why recurring revenue changes the business A $300 entry service once a year is unpredictable income: it depends on winning new clients every season. A client on monthly bookkeeping is income that arrives on its own, month after month, and that opens the door to even more services. Turning one-time buyers into recurring clients doesn't just raise revenue: it stabilizes the firm and cuts your dependence on spending for ads to survive every tax close. ## Why an accounting firm is the ideal case Accounting has a huge advantage for upsell: the tax calendar is predictable. There are dates when each type of client needs something. An agent that knows the calendar and knows your client can offer the right service exactly when it matters. On top of that, accounting services chain together naturally. Whoever files a return needs orderly bookkeeping. Whoever grows needs payroll. Whoever bills more needs tax planning. The agent connects those dots without your team having to think it through client by client. There is another practical reason: upsell done by hand always loses to whatever is urgent. When your team is closing filings, offering an extra service is the first thing to drop off the list, no matter how profitable. The agent doesn't get distracted or tired: it works the base in parallel, every day, without taking a single minute from your people's billable work. ## How we build it: the MAGIA method We use a five-step method: - **Mapping.** We capture your full catalog and the rules for when a client is a candidate for each service. - **Architecture.** We design how and when the agent starts each upsell conversation. - **Generation.** We build the agent in your firm's voice with the selling points for each service. - **Implementation.** We connect it to WhatsApp and your CRM and test it with real clients. - **Autonomy.** We hand it over running, working your base on its own. ## What it costs and what you keep Our entry package, **MAGIA Solo**, costs **$4,500 USD** and ships in **15 days**. It includes the WhatsApp AI agent and the CRM with the upsell and cross-sell logic over your client base. What matters: **the code, the data, and the infrastructure are 100% yours.** No retainers, no locked-in licenses. Operation is pass-through, usually **$200 to $400 USD a month** for hosting and tokens, with no markup from us. For firms with broad catalogs or several branches, **MAGIA Core** costs **$15,000 USD** and **Forge** **$20,000 USD** over 12 weeks. ## The next step The easiest money in your firm is in the clients you already have.

No. The agent offers the right service at the right moment, usually when the client already wrote in for something else or on key tax-calendar dates. It doesn't bombard: it spots the real opportunity and presents it in your firm's voice. ### How does it know which service to offer each client? Because it knows your catalog and every conversation lands in the CRM. From that it spots natural candidates: a client with employees for payroll, a growing one for tax planning. The candidacy rules are defined with you during mapping. ### What does it cost and how fast do I get it? MAGIA Solo costs $4,500 USD and ships in 15 days, with the WhatsApp agent and the CRM upsell logic. MAGIA Core is $15,000 and Forge is $20,000 for firms with broad catalogs or several branches. ### Who owns the code and my client data? You do, 100%: code, data, and infrastructure. No retainers, no locked-in licenses. Operation is pass-through, usually $200 to $400 USD a month for hosting and tokens, with no markup from us. ### Does it work if I only have around 50 clients? Yes. The value is in activating services your clients don't know you offer, no matter the base size. With 50 or 500, the agent works each client systematically and at the right time, something there is never enough time to do by hand. --- Source: https://catalizadora.ai/blog/accounting-firm-automatic-upsell-cross-sell-ai-agent Author: Pablo Estrada — AI Catalyst, LLC (catalizadora.ai)
