Meta Business Agent or a custom AI agent:which one fits for selling on WhatsApp
Meta has its own AI agent for WhatsApp, and for many businesses it is enough. This guide compares them criterion by criterion: where Meta's agent does the job and where you need an agent connected to your systems, without picking a side upfront.
Should you use Meta Business Agent or an AI agent connected to your systems?
Meta Business Agent is the right fit when your WhatsApp sales can be handled with your catalog, frequently asked questions and general business information: it goes live in minutes and has a free entry tier. An AI agent connected to your systems is the right fit when the answer depends on your data: customer-specific prices, ERP inventory, credit, rule-based quotes and records in Salesforce.
This is not a fight. Meta Business Agent is a good tool and, for a small business with a simple catalog, it is probably the most sensible choice. The useful question is not which one is better, but what the agent needs to know to answer your customer well, and where that data lives.
What Meta Business Agent is and what it does
Meta Business Agent is the AI agent Meta offers businesses to serve customers on WhatsApp, Messenger and Instagram. It answers questions about the business, recommends products from the catalog, books appointments, qualifies leads and can close sales; when a conversation is beyond it, it hands off to a person with the full history (Meta Newsroom, 2026).
It learns from what the business gives it: profile information, the catalog with its prices, the website, frequently asked questions and documents; in the WhatsApp Business app it also learns from past conversations. For large companies, Meta adds a platform with controls, measurement and connectors to third-party systems, naming Shopify, Zendesk and Shopee among them.
It can be turned on for free, and Meta has announced paid subscription plans for businesses of different sizes. On the official API, its replies are billed at USD 2 per million tokens, about 4 to 5 cents per reply depending on complexity (Meta for Developers, 2026). The rest of the rates are explained in how much the WhatsApp Business API costs.
When Meta Business Agent is the right choice
For many businesses, Meta's native agent is the right answer, and it is worth saying plainly. If your case looks like these, try it before you evaluate anything else.
- Simple catalog: one price for every customer, published in the catalog, with no customer-specific price lists or volume discounts.
- Frequently asked questions: hours, shipping, payment methods and return policies. The answers someone on your team copies and pastes.
- Appointments and bookings: the agent schedules them without anyone stepping in.
- Small business: a few people handling customers, everything goes through WhatsApp, Messenger or Instagram, and there is no CRM to feed.
- Starting right away: it is set up in minutes, with no implementation project involved.
A quick test: if a new hire could serve your customers well with just the catalog and a sheet of frequently asked questions, Meta Business Agent can probably do it too. If they would need to log into the ERP and check each customer's account, that is a different conversation.
When you need an agent connected to your systems
In B2B sales and in mid-size and large companies, the right answer is almost never in the catalog: it is in the ERP and the CRM. The customer does not ask for the list price, they ask for their price, with their discount, and whether there is stock to deliver on Thursday.
Meta's enterprise platform can connect to third-party systems, but the connection to your ERP, your business rules and your Salesforce objects is something someone has to build and maintain. That is where the real work is, and it is what the implementation of a connected agent takes care of. We explain the deeper difference between answering and selling in chatbot or AI agent.
- Customer-specific prices: different price lists by channel, region or account, and volume discounts that change depending on who is buying.
- Real-time inventory: what is in the warehouse according to the ERP, not what the catalog showed the last time someone updated it.
- Credit and account balance: knowing whether the customer has overdue invoices or available credit before taking the order.
- Rule-based quotes: minimum orders, discounts, payment terms and freight by region, applied the way your team would apply them. We cover it in automated quotes on WhatsApp.
- Records in Salesforce: every lead, quote and order lands in your CRM, in your objects and under your permissions, with no manual data entry.
- Handoff with context: the conversation reaches the right sales rep, with what the customer already said and what they were quoted.
Meta Business Agent and a connected agent, criterion by criterion
The table is not looking for a winner: each column describes what each tool is designed for. Read it with your own operation in mind, not in the abstract.
| Criterion | Meta Business Agent | Agent connected to your systems (like Sellium) |
|---|---|---|
| Catalog | Recommends products from the catalog you load into Meta, with their prices | Recommends from your catalog and cross-checks it with your ERP data |
| Customer-specific prices | Answers with the catalog price; a per-customer price list requires connecting the system where it lives | Applies each customer's price list and discounts, read from your ERP or Salesforce |
| Real-time inventory | Whatever is in the catalog or in the system you connect to it | Checks ERP inventory at the moment of the conversation |
| Quotes | Shares catalog prices; your own business rules have to be configured or integrated | Builds the quote with your rules: minimums, discounts, terms and freight |
| Account balance and credit | Requires connecting the ERP where that data lives | Checks balance and available credit before taking the order |
| CRM and Salesforce | Connectors to third-party systems on its enterprise platform; mapping to your objects is set up by you or an integrator | Runs inside Salesforce: reads and writes your objects, and respects profiles and permissions |
| Handoff to a sales rep | Passes the conversation to a person with the full history | Hands off to the person you define, with the context and the record already in the CRM |
| Language and local expressions | Replies in the customer's language and in the business's tone | Handles text and voice notes, trained on the vocabulary of your industry and your customers |
| Who sets it up | The business itself, in minutes from the app; on the platform, your technical team or a partner | Vantegrate, turnkey: process mapping, training and integration |
| Cost | Free to turn on; on the API, USD 2 per million tokens, about 4 to 5 cents per reply | Implementation quoted per company plus a monthly subscription with AI credits, no lock-in; you pay for messages directly to Meta |
Meta Business Agent data from Meta Newsroom and Meta for Developers (2026). Meta updates features and rates often: check the current ones in its documentation.
Can you use both?
Meta's documentation describes how they coexist on the same API number: when Meta Business Agent is active, a third-party app stays on standby and receives a copy of the conversation, and it can take control of a chat and hand it back to Meta's agent when it is done (Meta for Developers, 2026).
Possible does not mean advisable. The underlying question is one of architecture: one number, one agent replying to each customer at any given moment, and clear rules for handing off. If two agents work the same chat without a defined rule, the customer gets crossed answers and nobody knows what was recorded.
Before combining them, decide who answers first, when the conversation passes to the other one and where the record lives. If your sales depend on the ERP and Salesforce, the simplest setup is usually to let the connected agent answer and hand off to a person when needed.
How to decide in five steps
The decision comes from your own conversations, not from a product sheet. With these five steps you will know whether Meta's agent is enough or you need a connected one.
Gather the real questions
Take your last hundred WhatsApp conversations and sort them: which ones can be answered from the catalog and which ones need data from your system.
Find where each piece of data lives
Catalog, ERP, CRM, a spreadsheet or a sales rep's head. Whatever is not in the catalog, an agent cannot know without an integration.
Try Meta's agent with your catalog
It is free to turn on and takes minutes. It is the cheapest way to see what share of inquiries it handles on its own.
Measure what it hands off
Count how many conversations go to a person and why. If most handoffs are about prices, inventory or credit, the bottleneck is the integration.
Compare the total cost
Meta tokens, your team's hours on what gets handed off, and integration. The full breakdown is in [how much an AI agent for WhatsApp costs](/en/sellium/whatsapp-ai-agent-cost).

Caveats: Meta updates its features, rates and billing rules several times a year; check the current ones in its documentation. The cost per reply varies with the complexity of each conversation. The Harvard Business Review figure measures web leads contacted by phone or email, not WhatsApp, and is used as a reference for response speed.
