Here's how we build it. ## The prospect who messages on a Saturday and hears nothing back A small business owner finally decides they need an accountant. It's 9 p.m. on a Saturday. They message your firm on WhatsApp: "Hi, do you handle corporate tax filings? What are your fees?" No one answers until Monday at 11 a.m. By then they've already messaged three other firms. Whoever replied first, clearly and in their language, won the client. For accounting firms, the problem is rarely a shortage of prospects. It's that they arrive at odd hours, they all look alike at first glance, and your team is buried in closings, filings and reconciliations. Sales follow-up always comes second. And a lead left unanswered for an hour is a lead already talking to your competitor. At Catalizadora we build AI agents that reply on WhatsApp in your firm's voice. Not a button-menu chatbot. An agent that holds a real conversation, understands what the person needs, qualifies them, and carries them all the way to a booked meeting with you, in the tone you'd actually use. ## What "in your brand voice" really means A serious accounting firm doesn't talk like a food-delivery app. Trust is the product. If your manner is formal and precise, the agent answers formal and precise. If your firm is warm and patient because you serve founders who barely understand tax rules, the agent explains carefully and skips the jargon. This isn't cosmetic. It's what keeps the prospect from feeling they fell into an automated form. During Mapping, the first phase of our MAGIA methodology, we sit down to understand how you speak: the questions you always ask before quoting, how you frame your fees, the objections you hear over and over, which clients you actually want and which you don't. From that, the agent learns to: - Tell a sole proprietor apart from a corporation and adjust the conversation. - Ask what you would ask: entity type, rough monthly revenue, whether they already have an accountant, what made them look for a new one. - Explain your fee model without committing you to a number that doesn't apply. - Recognize when someone only wants a price and isn't a fit, so it doesn't waste your time. ## Replying fast is half of it. Selling is the other half Answering in seconds already sets you apart. But the agent doesn't stop at answering. It drives the conversation toward a concrete next step. ### It qualifies before it hands you the lead Not everyone who messages is worth your hour. The agent filters. A freelancer billing very little and hunting for the cheapest option is not the same as a company with 30 employees on payroll and compliance headaches. The agent understands the difference and prioritizes, so when you enter the conversation you already know who you're talking to. ### It books the meeting without the back-and-forth The endless ping-pong to settle a time kills deals. The agent offers real openings from your calendar and closes the appointment right there. The prospect lands on your calendar without you lifting a finger. ### It sends the payment link when it applies If you sell fixed-price packages, an initial advisory session or an onboarding fee, the agent can send the payment link inside the same conversation. The client pays without ever leaving WhatsApp. ### Everything lands in your CRM Every conversation is logged: what they asked, how they qualified, what was offered, whether they booked. Nothing lives only on the phone of whoever replied. Your firm finally has a real sales history. ## The number that matters: response time Run the math on your own firm. How many messages arrive after hours? How many wait more than an hour for a reply? Each one is a high probability of a lost client. An agent that replies in seconds, around the clock, doesn't burn out in tax season, doesn't take April off, and never leaves a message on read. It doesn't replace your accounting team. It frees your team from front-line sales so they can focus on the work you actually bill for. ## We build it so it's yours Here's the difference that matters most to a firm: the code, the data and the infrastructure are 100% yours. We don't rent you a bot or lock you into a perpetual monthly license. No retainers. The fastest agent to ship is MAGIA Solo: 4,500 USD, delivered in 15 days. It includes the agent in your brand voice, connected to WhatsApp and your CRM. Monthly operation is pass-through, roughly 200 to 400 USD a month for hosting and tokens, with no markup from us. If your firm needs something larger, integrating your accounting system, multiple flows, multiple offices, that's where MAGIA Core (15,000 USD) or Forge (20,000 USD over 12 weeks) come in. In every case, what we build stays with you. If you decide to run it yourself tomorrow, you can. ## The next step If your firm loses clients by not replying in time, or your team burns hours answering the same questions before every quote, an agent that speaks in your brand voice solves it.

No. It handles front-line sales on WhatsApp: it replies, qualifies, books and logs to your CRM. Your team focuses on the billable accounting work, without losing prospects to slow responses. ### What does it cost and how fast is it delivered? The brand-voice WhatsApp agent starts with MAGIA Solo: 4,500 USD, delivered in 15 days. For deeper integrations with your accounting system or multiple offices, MAGIA Core is 15,000 USD and Forge is 20,000 USD over 12 weeks. ### Will the bot sound robotic to my clients? It's not a button menu. During Mapping we learn how your firm speaks, the questions you ask before quoting and how you explain fees, so the agent converses in your real tone, formal or warm depending on your brand. ### Who owns the code and data? You do, 100%. The code, data and infrastructure are in your name. No retainers, no locked-in licenses. Monthly operation is pass-through, 200 to 400 USD, with no markup from us. ### How do I start?
