Regular WhatsApp, Business and Business API: which to use for your business
Meta offers 3 different versions of WhatsApp. Each one solves a different problem and has a different cost. Mixing them up costs money (or gets your number blocked). Let's clarify once and for all.
Version 1: Regular WhatsApp (personal)
The green app you install on your phone. Free forever.
- For: personal use, chats with friends/family.
- Who answers: just you on your phone.
- Limit: no formal limit, but Meta may ban you if it detects commercial use.
- Cost: free.
- Multi-agent: no. One phone, one account.
- Automation: not officially supported.
DO NOT USE FOR BUSINESS. Customers reaching out on a personal number = risk of being blocked + lack of professionalism.
Version 2: WhatsApp Business (app)
Separate app installed on your phone, identified with a "Business" badge. Free forever.
- For: freelancer, solo entrepreneur, micro-company with 1 person answering.
- Who answers: 1 person on the phone (up to 4 linked devices: 1 primary + 3 connected).
- Limit: commercial use OK. No daily message cap (but Meta bans if it turns into spam).
- Cost: free. You only pay your data plan.
- Multi-agent: limited. 4 linked devices, but all see every conversation (no per-agent separation).
- Automation: quick replies (50 manual templates), away message, greeting.
- Catalog: yes, up to 500 products visible on the profile.
- Labels: 20 labels to organize chats.
- Bulk messaging: not recommended. Breaks ToS past ~10 contacts without opt-in.
USE IT WHEN: you handle support alone, get up to 50 messages/day, and don't need smart automation.
Version 3: WhatsApp Business API (Cloud API)
Official Meta integration. No dedicated phone, no app — you connect via an intermediary platform or Cloud API directly.
- For: growing SMB, e-commerce, company with a support team.
- Who answers: unlimited. 5, 10, 50 agents on the same number, with a dashboard.
- Limit: starting tier of 250 business-initiated conversations/24h. Grows to 1k, 10k, 100k as quality improves.
- Cost: Meta charges per conversation (utility ~$0.015, marketing ~$0.07, service free). Intermediary platform starting at ~$19/month.
- Multi-agent: yes, with queue separation, automatic assignment, agent-to-agent transfer.
- Automation: AI bot, flow chatbot, CRM/ERP integrations, official webhooks.
- HSM templates: yes, with Meta approval. Allows sending outside the 24h window.
- Bulk messaging: yes, via approved templates (broadcast).
USE IT WHEN: you exceed 50 messages/day, need 24/7 coverage, or have a team handling support.

When to switch
- Personal → Business app: immediately, as soon as you open a business. Real risk of getting banned using a personal account for commercial use.
- Business app → API: when you get 50+ messages/day, hire a 2nd person to handle support, or want to push promos to 100+ contacts.
Common myths
"The API is just for big companies." — Myth. An SMB with 50 msgs/day already gets more value than it pays for.
"I'll lose my history when migrating." — Myth. History migrates with you. It just doesn't work in the old app (the number becomes API only).
"The API is hard to set up." — Was, back in 2020. In 2026 with Meta's official Embedded Signup, you activate it in 3 minutes via a Facebook popup.
Move from Business app to API without hassle
MercaBot handles the migration in ~3 minutes via official Meta Embedded Signup. You keep the same number, history is preserved, and the bot answers 24/7.
