AI WhatsApp agents for your ERP: the code stays in your account

An AI agent for WhatsApp isn't a button menu: it understands what the customer writes, checks your systems (appointments, stock, prices, customers) and carries out the action: book, reschedule or load an order into your ERP. When something needs a person, it hands the conversation to your team with the full context. It runs on the official WhatsApp API, on your number, and the code and infrastructure stay in your account.

What usually happens

  • WhatsApp fills up with repeated questions and the team stops handling what matters.
  • Appointments or orders are written down by hand and later don't match the calendar.
  • After hours nobody replies and the customer writes to someone else.
  • You tried a flow-based bot and it breaks as soon as the customer writes something unexpected.

What we deliver

  • Agent on the official WhatsApp API (Meta Cloud API), on your number.
  • Integration with your calendar, spreadsheet, CRM or management system to read and write real data.
  • Conversation panel with human handoff and the ability to pause the agent.
  • Automatic reminders and notifications using Meta-approved templates.
  • Repository, database and infrastructure in your account: no platform in between.

Which systems we connect it to

The agent always uses the same operations (identify customer, search products, check stock and prices, create an order or appointment) and only the connector changes. We confirm it in discovery, before committing to scope.

  • ERPs: Tango Gestión, öppen, Odoo and others with an API or accessible database.
  • Calendars and spreadsheets: Google Calendar, Google Sheets, Excel.
  • CRMs and in-house systems, including old ones (Java, VB6, Access, PHP).

Integrations

Frequently asked questions

How much does a WhatsApp agent cost?
It is quoted after the one-week discovery, because it depends on the systems to integrate and the business rules. Meta's per-message charges are separate and detailed in our WhatsApp API cost guide.
Can I keep my WhatsApp number?
Yes. The number is connected to the official WhatsApp Business API. Your customers keep writing to the same number.
What happens when the agent doesn't know something?
It only answers with the information and systems we connect. If it can't resolve something, it hands the conversation to your team and flags it in the panel.
How much does Meta charge for messages?
Meta charges per delivered message based on category and the recipient's country. In Argentina, since October 1, 2026, a utility message (confirmation, reminder) costs USD 0.026. We break it down in our pricing guide.
What does it mean that the code stays in my account?
Each agent is its own project: repository, database and deployment in your account. If you work with another team tomorrow, you hand it over. You don't depend on a platform subscription.
How long until it's live?
A one-week discovery and go-live in 2 to 3 weeks, depending on which systems need to be integrated. With systems that have no API or are very old it can take longer, and you'll know before we start.
