WhatsApp Business API pricing has two parts: what Meta charges per conversation, and what your platform charges for the software (AI, inbox, automation). Understanding both keeps your costs predictable.
- Meta bills per 24-hour conversation, priced by category — not per message.
- Service conversations started by the customer are often the cheapest; marketing costs more.
- Your platform adds a separate, flat software fee on top.
Part 1: Meta's conversation charges
Meta charges per conversation — a 24-hour window — and the price depends on the category:
| Category | Started by | Typical use |
|---|---|---|
| Service | Customer | Replies to customer questions |
| Utility | Business | Order updates, reminders, confirmations |
| Marketing | Business | Offers, promotions, re-engagement |
| Authentication | Business | One-time passcodes |
Marketing conversations are the most expensive; service conversations are usually the cheapest, and a number of service conversations may be free each month.
Part 2: The platform fee
On top of Meta's charges, your provider bills for the software layer — the AI agent, shared inbox, broadcasts, booking, and CRM. This is usually a simple monthly plan.
A simple example
If most of your volume is customers messaging you (service) with some reminders (utility) and occasional promotions (marketing), your Meta cost scales with conversation count, while the platform fee stays flat. As AI deflects repetitive questions, your cost-per-outcome drops.
Exact Meta rates vary by country and change over time. For a precise Saudi estimate, map your monthly conversation volume by category — we'll do this with you in a demo.
Keeping costs down
- Let the AI resolve service conversations instead of paying staff time.
- Use utility templates (cheaper) for reminders instead of marketing where appropriate.
- Avoid manual mass-messaging that risks bans and wasted spend.
