AI sales agent for WhatsApp in Colombia:from the quote to payment with PSE or Nequi
Your customers in Colombia message you on WhatsApp to get a quote, place the order and ask when it will arrive. Sellium answers them in seconds, in Spanish, with your real prices and inventory, collects with PSE, Nequi or card, can generate the sales invoice in Siigo and logs everything in your CRM. We implement it remotely from Argentina in 4 to 6 weeks, working with your team in English.
How does an AI sales agent on WhatsApp work for a company selling in Colombia?
An AI sales agent for a company selling in Colombia connects to the official WhatsApp Business API with your number, to your accounting system or ERP and to your CRM. It serves each customer at any hour, in Spanish, quotes from their price list, takes the order, collects with PSE, Nequi or card through a gateway such as Wompi and can generate the sales invoice in Siigo, without anyone typing it in.
Sellium is that agent. The Vantegrate team configures it, integrates it and launches it remotely from Argentina: we have no office in Colombia, 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 Colombia's rates and on your own account. What an AI agent handles in other areas is covered in our guide to enterprise AI agents.
What a WhatsApp sale looks like in Colombia, end to end
In Colombia, a WhatsApp sale rarely ends in the chat. The buyer asks for a quote, pays from online banking (PSE) or from their phone (Nequi), expects an e-invoice and asks about the delivery. Each step lives in a different system, and when nothing connects them, someone copies the data from one to the next by hand.
An integrated agent covers that whole journey in the same conversation, in Spanish, while your team follows the sale from wherever it works. These are the five moments where time, or the sale, usually gets lost when everything depends on a person checking dashboards.
- Quote: with the price list that applies to each customer, their volume discounts and real inventory, not last month's price PDF.
- Collect: the payment link with PSE, Nequi or card, generated for the exact order amount and confirmed as soon as it is approved.
- Invoice: the sales invoice generated in Siigo when the opportunity is won, with its status sent back to the CRM.
- Ship: the status of the Coordinadora or Servientrega waybill, answered in the same chat when the customer asks.
- Hand off: whatever needs a person goes to your team with the full conversation, without the customer repeating anything.
Integrations with the systems companies use in Colombia
A sales agent is only as reliable as the data it checks. That is why Sellium works on the systems your Colombian operation already uses: your accounting software, your payment gateway and your carrier. The table summarizes Vantegrate's documentation for each integration, including how it connects.
| System | What Sellium does with it | How it connects |
|---|---|---|
| Siigo (accounting and e-invoicing) | Quotes with your catalog and prices and, when an opportunity is won, can generate the sales invoice in Siigo and return its status | Siigo API, with token authentication based on the account's credentials |
| Wompi (payment gateway) | Creates the charge by card, PSE or Nequi and confirms when the payment clears | Wompi's official API; the webhook reports every change in the payment status |
| PSE (bank debit run by ACH Colombia) | Creates the charge by bank debit and confirms the debit status | Through the gateway or aggregator that already has PSE enabled for your business |
| Nequi (digital wallet) | Collects with a QR code or a notification to the customer's phone, and checks the payment status | Nequi Conecta API, or Nequi as a payment method inside a gateway such as Wompi |
| Coordinadora (carrier) | Tells the buyer the shipment status and delivery date in the same conversation | Coordinadora's official web service or its store plugins |
| Servientrega (carrier) | Reports the shipment status inside the conversation, so tracking does not move to another channel | Servientrega's official web services |
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, and with Salesforce or HubSpot as the CRM, 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, and how payment works inside the conversation, in collecting payments on WhatsApp.
How much Meta charges per WhatsApp message in Colombia
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 Colombia, a marketing message costs USD 0.0125 and a utility message USD 0.0008 (EngageLab, 2026).
In practice, confirming an order or announcing a shipment with a utility template costs a fraction of a US cent. And the agent's replies when the 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.
| Category | What it is used for in sales | Rate for a number in Colombia |
|---|---|---|
| Marketing | Promotions, campaigns and reviving a quote outside the 24-hour window | USD 0.0125 per delivered message |
| Utility | Order confirmation, shipping notice and payment reminder | USD 0.0008 per delivered message |
| Service | The agent's replies inside the 24-hour window the customer opens | 1,000 free per number per month; after that, USD 0.0008 |
Sources: EngageLab (2026) for marketing and utility, 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 Colombia's rates. The full model is in how much the WhatsApp Business API costs.
What Sellium sells on WhatsApp to buyers in Colombia
The person writing in and what needs checking vary, but the flow is the same: understand, validate, confirm and record. These are the cases where selling on WhatsApp carries the most weight, each with its own detail page.
| Industry | Who writes in | What the agent handles |
|---|---|---|
| Consumer Goods | Neighborhood stores, mini-markets and small supermarkets that restock between one route rep visit and the next | Takes the order with the channel's price list and current promotions, and checks inventory at the warehouse that supplies the area |
| Wholesale Distribution | Hardware stores, drugstores and resellers that order by code or by description | Finds the product among thousands of SKUs, applies the price list for their tier and checks their credit limit |
| Construction Materials | Builders, contractors and site foremen ordering for the job site | Quotes by volume, confirms the delivery date and respects each account's credit |
| Industrial Machinery | Customers looking for a spare part for a specific machine | Identifies the machine, confirms the part is compatible and quotes with inventory |
| Automotive | People asking about a vehicle, a financing plan or a test drive | Answers with real inventory, puts the plan together and books the test drive |

Remote service from Argentina: what it means for your project
Vantegrate serves its customers in Colombia remotely, from Argentina. We have no office in Colombia, 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 Colombia 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 Colombia are only a few hours apart, so working sessions fall within the Colombian 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 Colombia, Mexico and much of Latin America. The full story is on our About page.
How Sellium is implemented for your business in Colombia, 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.
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.
Discovery
The first two weeks: we map your sales process, catalog, pricing rules and channels. By the end, the agent's scope is defined.
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.
Configuration and integration
We connect the agent to your CRM, to Siigo or your ERP, to your payment gateway and to your carrier, and train it on your real information.
Validation with real cases
We test with real conversations from your customers and fine-tune with your sales team before opening it to everyone.
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, which is why it is worth checking the current rate in its documentation. The Nequi figure counts wallet accounts, not B2B buyers: it is used as a reference for how widespread the payment method is.

What companies selling in Colombia ask before putting an AI agent to work selling on WhatsApp.
Is Sellium available for companies selling in Colombia?
Is Sellium available for companies selling in Colombia?
Yes. Sellium works with your Colombian number connected to the official WhatsApp Business API, and the Vantegrate team implements it remotely from Argentina. We have no office in Colombia: discovery, configuration and testing happen over video calls, and the agent serves your customers from the cloud around the clock.

Does it integrate with Siigo?
Does it integrate with Siigo?
Yes. Siigo is a Colombian accounting and e-invoicing platform, and Sellium connects to it through its official API: it reads customers, products and invoices to quote with your real data and, when an opportunity is won, can generate the sales invoice in Siigo and return its status to the CRM. The exact scope is validated with your account; how an ERP or accounting system connects to the agent is covered in selling on WhatsApp with your ERP.
Can it collect payments with PSE or Nequi on WhatsApp?
Can it collect payments with PSE or Nequi on WhatsApp?
Yes. The most common way is through a gateway such as Wompi, which offers card, PSE and Nequi in a single charge: the agent creates the payment for the order amount, the customer pays without leaving the chat and the webhook reports when it clears. PSE is the bank-debit system run by ACH Colombia; Nequi, a digital wallet, also connects through its own API, with a QR code or a notification to the customer's phone. The agent never asks for bank or card details in the chat.
How much does Meta charge per WhatsApp message in Colombia?
How much does Meta charge per WhatsApp message in Colombia?
Meta charges per delivered message, by category and by the recipient's country, so messages to buyers in Colombia pay Colombia's rates even if your company is based elsewhere: USD 0.0125 per marketing message and USD 0.0008 per utility message (EngageLab, 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.
Can it share shipment status with Coordinadora or Servientrega?
Can it share shipment status with Coordinadora or Servientrega?
Yes. Through its integration with Coordinadora or Servientrega, two Colombian carriers, the agent reads the waybill status and tells the customer, in the same conversation, where their order is and when it will arrive, without anyone logging in to the carrier's portal.
