Best CRM with WhatsApp: how to choose the right one

"What's the best CRM with WhatsApp?" doesn't have one answer. A shop with two people replying from their phones needs something very different from a dental office with five front-desk staff, or a sales team sending campaigns to thousands of contacts. What you can do is compare your options against the same criteria and see which one fits how you work.

This page lays out those criteria, gives you a checklist to take into demos, and shows where Elooo System stands on each point, so you can hold it up against whatever else you're being offered.

The criteria that actually matter

1. How WhatsApp is connected: QR code or official API

Ask this first. A QR code connection links the WhatsApp on a phone to the CRM: it's quick and needs no approval, but it depends on that device staying connected. The official API (WhatsApp Business Platform) is Meta's business connection: more stable, designed for teams, and with its own rules.

The main official API rules, according to Meta's pricing documentation:

• when a customer messages you, a 24-hour customer service window opens;
• inside that window you can send free-form messages;
• outside it you can only send approved message templates (marketing, utility or authentication);
• Meta charges per delivered template message, with rates that vary by category and by the recipient's country.

2. Several agents on one number

If more than one person talks to customers, you need a shared inbox with conversation assignment and a history everyone can see. Ask whether the CRM lets several agents work the same number, and whether that depends on the official API.

3. Multichannel inbox

Customers don't only use WhatsApp. Having Instagram, Facebook Messenger, email and SMS in the same inbox keeps a request from slipping through because it came in on the "wrong" channel.

4. Pipeline tied to the conversation

This is what separates a CRM from a messaging tool: open a chat and see, right next to it, which stage the deal is in, the history and the open tasks. Without that, WhatsApp is just a list of chats with no process. Our WhatsApp sales guide walks through building that process.

5. Automations and templates

Welcome replies, appointment reminders, follow-ups on quotes that went quiet. Check whether automations support triggers, waits and conditions, and whether there are ready-made templates to adapt.

6. AI

An AI agent can answer after hours, ask qualifying questions and book meetings. Confirm that the AI uses your business information, hands the conversation to a person when it should, and which plan includes it.

7. Per-message cost vs flat price

Add up three things: the CRM's price, any per-message fee the CRM charges, and Meta's costs on the official API. For example, if you send weekly reminders to hundreds of customers, per-message pricing weighs far more than for a business that only replies to inbound messages.

8. Users included

Many CRMs charge per seat. If your team is going to grow, or you want to give view-only access to more people, the math changes.

9. Mobile app

People who sell in the field need to reply and update the pipeline from their phone, with notifications for new leads.

10. Data protection

Your CRM will store your customers' personal data. Ask for the privacy policy and the data processing agreement, and confirm the vendor's role (processor). If you serve customers in the EU, GDPR applies; in Brazil, the LGPD.

Evaluation checklist

Use this table in a demo or when comparing proposals. The last column shows where Elooo System stands.

When Elooo System may not be your best pick

Be realistic about your operation. If all you need is the official API on a tight budget, note that Elooo System only offers the official API on the Enterprise plan. If you just want a messaging tool, with no pipeline, automations or marketing, something simpler may be enough. Our prices are in euros, so compare the converted amount with tools billed in dollars. And if you're already weighing a specific tool, see Elooo System vs Kommo for a point-by-point comparison.

How to decide in three steps

1. Write down how many people handle WhatsApp today and how many will a year from now.
2. Decide whether you can rely on a connected phone (QR code) or need the official API.
3. Run each candidate through the checklist above and add up the total monthly cost, including messages.
