B2Chat alternative — WhatsApp CRM for appointment-based teams

Editorial disclosure: I work at Zellbox, so this post is naturally biased. I’ve tried to describe B2Chat as accurately as possible based on their pricing page and product page as of August 2026. If you find a factual error, message me on LinkedIn and I’ll fix it. No affiliate links.

If you’re evaluating B2Chat alongside other WhatsApp platforms, you’ve likely also seen Callbell, Sirena, Auronix, or Zoko. B2Chat is a multi-channel messaging inbox popular with sales and support teams across Latin America. Zellbox is built for a different shape of business — appointment-driven small businesses (clinics, salons, vets, physios, fitness studios) that need WhatsApp reminders tied to a real calendar.

Where B2Chat fits

B2Chat is at its best when your day is a shared queue. Sales teams handling many WhatsApp leads at once, support teams handling multi-channel enquiries — B2Chat’s inbox with agent-assignment + canned replies + basic CRM fits that shape. Strong in Colombia, Mexico, Peru, and neighbouring markets.

Where Zellbox fits

If your business runs on visits, the queue isn’t leads — it’s tomorrow’s booking list. Zellbox syncs with Google Calendar, fires 24 h + 2 h reminders automatically, and stores signed consent PDFs on each customer record. Setup takes ~10 minutes; the free tier handles a real workload before any spend.

Feature-by-feature

When to pick which

Pick B2Chat if: you’re a LATAM sales or support team running multi-channel conversations and per-agent pricing works for your team size.

Pick Zellbox if: your business runs on appointments and you want WhatsApp reminders that know your calendar. Free tier covers 100 reminders/month with no BSP setup.

Migration checklist: switching from B2Chat

If B2Chat’s multi-channel sales queue has been more capacity than a single appointment-based team actually needs, moving to Zellbox is a data-export + reconnect exercise, not a rebuild.

Export your B2Chat contacts and conversation history

Pull your customer directory and WhatsApp conversation history out of B2Chat’s dashboard before you switch — the platform lets you export contacts and chat logs as a CSV from account settings. Note down the handful of approved WhatsApp templates you actually send so you’re not recreating message copy from scratch on the new side.

Reconnect your WhatsApp Business number to Zellbox

Your WhatsApp Business Account (WABA) and phone number belong to Meta, not to B2Chat, so the number itself is portable. In Zellbox, use the Embedded Signup flow to re-point that same WABA at Zellbox’s infrastructure — about 10 minutes, no new number required, and no loss of message history with existing customers.

Rebuild your automations and templates in Zellbox

Recreate the handful of templates you actually send (appointment confirmation, 24 h reminder, 2 h reminder) inside Zellbox’s template library — appointment-driven teams typically need 3-5, far fewer than a multi-channel sales inbox accumulates over time. Import your exported contacts, connect Google Calendar, and reminders start firing automatically with no agent-assignment queue to maintain.
