AI sales agent for WhatsApp in Mexico:connected to your systems and your local payments

Your customers in Mexico message you on WhatsApp to get a quote, place an order and ask about their shipment. Sellium answers them in seconds, in Spanish, with your real prices and inventory, collects payment through Conekta or Clip and logs everything in your CRM. We implement it remotely from Argentina in 4 to 6 weeks, working with your team in English.

The short answer

How does an AI sales agent on WhatsApp work for a company selling in Mexico?

An AI sales agent for a company selling in Mexico connects to the official WhatsApp Business API with your number, to your ERP and to your CRM. It serves each customer at any hour, in Spanish, quotes from their price list, takes the order, collects by card, SPEI or OXXO Pay through Conekta, or with a Clip payment link, and records the sale without anyone keying it in.

Sellium is that agent. The Vantegrate team configures it, integrates it and launches it remotely from Argentina: we have no office in Mexico, and the project does not need one, because the agent runs in the cloud, connected to your systems, wherever your team is based. You pay Meta directly for WhatsApp messages, at Mexico's rates and on your own account. Beyond sales, see what an AI agent does in each area of a company in our guide to enterprise AI agents.

The context

Mexico, the first country with AI agents on WhatsApp Business

Mexico was the first country where Meta launched its AI agent for WhatsApp Business, according to Expansión. Meta described it as a priority market: WhatsApp Business leads the adoption of digital tools among Mexican small and midsize businesses, and for many of them it is the first, and sometimes the only, point of contact with their customers.

For a midsize company selling into Mexico, that cuts two ways. First, your buyers get used to businesses answering them instantly on WhatsApp, at night and on weekends too, and they expect the same from a supplier based abroad. Second, Meta's agent answers with the catalog and general business information, which is enough for many small shops, but it does not know your customer-specific price lists, your ERP inventory or each account's credit.

That is where an agent integrated with your systems comes in. The full comparison, criterion by criterion, is in Meta Business Agent or a custom AI agent.

  • Instant quotes: with the price list that applies to each customer, their volume discounts and their promotions.
  • Orders without manual entry: from a text, a voice note or the photo of a list to the sales order in your system.
  • Payment in the conversation: card, SPEI bank transfer or OXXO Pay, without the customer leaving the chat.
  • Shipment tracking: the status of the Estafeta waybill, answered in the same chat.
  • Handoff with context: whatever needs a person goes to your team with the full conversation.
Local integrations

Integrations with the systems companies use in Mexico

A sales agent is only as reliable as the data it checks. That is why Sellium works on the systems your Mexican operation already uses: it collects through your local payment gateway, queries your accounting and admin software and sends shipping updates through your carrier. The table summarizes Vantegrate's documentation for each integration, including how it connects.

SystemWhat Sellium does with itHow it connects
Conekta (payment gateway)Creates the charge when the sale closes: credit or debit card, SPEI bank transfer or an OXXO Pay reference the buyer pays in cash at an OXXO storeOfficial API with an API key; webhooks report when the payment clears
Clip (payment platform)Sends a Clip payment link inside the conversation and confirms when the payment is completeClip's Checkout API; the webhook delivers the completed payment for reconciliation
Contpaqi (accounting and ERP)Checks a price or inventory in the middle of a sales conversation, without the rep switching screensDesktop SDK for the classic products or the REST API of Contpaqi Nube, its cloud line, depending on the product
Aspel (accounting and admin software)The administrative data stays in your Aspel; what the agent can query is defined during discoveryThe connection path is validated case by case, by product and version
Estafeta (parcel carrier)Tells the customer the status of their shipment and answers where the order is without switching channelsEstafeta's official web services for shipping quotes, waybills and tracking

Summary of Vantegrate's integration documentation. The exact connection path for each system is validated during discovery, before we quote.

Running another system? Sellium also works with SAP, Oracle, NetSuite, Odoo and other ERPs, with Salesforce or HubSpot as the CRM and with Stripe for card payments, so if your headquarters already runs one of them, the agent can work on that same stack. How the data comes together is explained in selling on WhatsApp with your ERP.

Meta's fees

How much Meta charges per WhatsApp message in Mexico

Meta charges for the WhatsApp Business API per delivered message, at a rate set by the recipient's country and the message category, not by where your company is based. For customers in Mexico, a marketing message costs USD 0.0397 (Leadsales, 2026) and a utility message USD 0.0085 (Simla, 2026).

The agent's replies when a customer writes in are service messages: the first 1,000 each month are free per number, and after that they are billed at the utility rate. In an operation with a modest volume of inbound conversations, that allowance covers a good share of the replies.

CategoryWhat it is used for in salesRate for a number in Mexico
MarketingPromotions, campaigns and reviving a quote outside the 24-hour windowUSD 0.0397 per delivered message
UtilityOrder confirmation, shipping notice and payment reminderUSD 0.0085 per delivered message
ServiceThe agent's replies inside the 24-hour window the customer opens1,000 free per number per month; after that, USD 0.0085

Sources: Leadsales (2026) for marketing, Simla (2026) for utility and service, and Meta for Developers (2026) for the 1,000 allowance. Meta updates its rates several times a year and offers volume discounts on utility: check the current rate in its documentation.

You pay these directly to Meta: on your own WhatsApp Business account, with no Vantegrate markup. To estimate your month with your volumes, use the WhatsApp API cost calculator, which comes preloaded with Mexico's rates. The full model is in how much the WhatsApp Business API costs.

How we work

Remote service from Argentina: what it means for your project

Vantegrate serves its customers in Mexico remotely, from Argentina. We have no office in Mexico, and we would rather say so up front so you know exactly how the work gets done.

In a project like this, distance matters less than it seems: the agent runs in the cloud and connects to your systems with the permissions you grant, and discovery, configuration and validation happen over video calls with your team, whether it sits in Mexico or in another country.

  • No travel, no local office: discovery, configuration and testing happen over video calls, with remote access to your systems.
  • Compatible hours: Argentina and Mexico are only a few hours apart, so working sessions fall within the Mexican business day.
  • The agent does not depend on distance: it serves your customers 24 hours a day, every day, from the cloud.
  • Your account and your data: the WhatsApp number and the Meta account belong to your company, and your information stays in your systems.
  • Your buyers' Spanish: the agent speaks to your customers the way your brand does, formally or informally, with your catalog's vocabulary, while our team works with yours in English.

Experience in the region: Vantegrate was born from the union of Ventix Solutions and EGA Futura, whose technology has users in Mexico, Colombia and much of Latin America. The full story is on our About page.

Step by step

How Sellium is implemented for your business in Mexico, in 4 to 6 weeks

The same method we use across the region, done remotely. The details of each stage are in how an AI sales agent is implemented.

1

First conversation

A video call to understand what you sell, which systems you work with, how you collect payment and how many conversations come in. With that, we put together the quote.

2

Discovery

The first two weeks: we map your sales process, catalog, pricing rules and channels. By the end, the agent's scope is defined.

3

Number and official API

We connect your number to the official WhatsApp Business API with your company's Meta account. If you sell from the app, we guide you through the migration.

4

Configuration and integration

We connect the agent to your CRM, your accounting and admin system, your Conekta or Clip payments and your carrier, and train it on your real information.

5

Validation with real cases

We test with real conversations from your customers and fine-tune with your sales team before opening it to everyone.

6

Gradual launch

We turn the agent on in production in stages, with our team alongside you at every step and the metrics in view.

Caveats: Meta updates its rates several times a year and offers volume discounts on utility and authentication; some providers publish rates that include their own margin, which is why it is worth checking the current rate in Meta's documentation. The Meta agent that launched first in Mexico is a different tool from Sellium: it answers with general business information, not with your systems.

Frequently asked questions

Frequently asked questions about Sellium in Mexico

What companies selling in Mexico ask before putting an AI agent to work selling on WhatsApp.

Is Sellium available for companies selling in Mexico?

Yes. Sellium works with your Mexican number connected to the official WhatsApp Business API, and the Vantegrate team implements it remotely from Argentina. We have no office in Mexico: discovery, configuration and testing happen over video calls, and the agent serves your customers from the cloud around the clock. The project runs the same way whether your team sits in Mexico or in another country.

Does it integrate with Contpaqi or Aspel?

With Contpaqi, yes: it connects through the desktop SDK or the Contpaqi Nube REST API, depending on the product, to check prices and inventory during the conversation. With Aspel, the exact path is validated case by case, by product and version. Both are Mexican accounting and administrative systems. Sellium also works with SAP, Oracle, NetSuite, Odoo and other ERPs; how an ERP connects to the agent is covered in selling on WhatsApp with your ERP.

Can it collect payments by SPEI or OXXO Pay on WhatsApp?

Yes, with Conekta. When the sale closes, the agent creates the charge and the customer chooses how to pay: card, a SPEI transfer (Mexico's interbank electronic payment system) or an OXXO Pay reference to pay in cash at an OXXO convenience store. Conekta's webhook reports when the payment clears, and the agent records it. With Clip, it sends a payment link. In no case does it ask for card details in the chat.

How much does Meta charge per WhatsApp message in Mexico?

Meta charges per delivered message, by category and by the recipient's country, so messages to buyers in Mexico pay Mexico's rates even if your company is based elsewhere: USD 0.0397 per marketing message (Leadsales, 2026) and USD 0.0085 per utility message (Simla, 2026). The agent's replies inside the 24-hour window include 1,000 free messages per number per month. Run your numbers in the WhatsApp API cost calculator.

What is the difference between Sellium and Meta's AI agent?

Meta's agent answers with the catalog and general business information, which is enough for many small shops. Sellium works with your systems: it quotes from each customer's price list, checks inventory in your ERP, collects through your payment gateway and logs everything in your CRM. The full comparison is in Meta Business Agent or a custom AI agent.

How much does Sellium cost for a company selling in Mexico?

Sellium is priced in two parts: an initial implementation quoted for each company and a monthly subscription with AI credits that scale up, with no lock-in. You pay for WhatsApp messages directly to Meta, on your own account and with no markup from us. To get a price for your case, request a quote with your volume and your systems.
