Simple, transparent pricing. Zero markup on your messages.
Six plans covering WhatsApp, Instagram, Facebook, email and website chat. Your first agent is free, and Meta bills your WhatsApp messages directly at its own rate with nothing added by us.
Every plan except WhatsApp API includes all five channels in one shared inbox, automatic conversation assignment, WhatsApp Coexistence so you keep your number, broadcasts and campaigns, drag-and-drop bot flows, message templates, the website chat widget, and reporting across every channel. The AI chatbot, calling and the AI receptionist are what the paid plans add.
It means the rate you pay Meta is Meta’s rate. Some providers add a percentage on top of every message, or resell messages in bundles at their own price. Omni Chat Stack does neither: Meta bills your account directly, we never touch the message rate, and we earn only the per-agent platform fee.
You link your official WhatsApp Business Account directly. Meta bills message fees straight to your card at official published rates. Zero markup, zero hidden commissions.
Other platforms frequently add 15%–30% on top of Meta's rates, force prepaid credit bundles that expire, or add per-conversation gateway surcharges.
Meta charges per message, by category and by the country your customer is in. Marketing messages cost the most; utility, authentication and service messages share a lower rate in each market. From 1 October 2026 Meta also charges for replies sent inside the 24-hour customer service window. Incoming messages from your customers are always free.
| Category | What it's for | Cost |
|---|---|---|
| Service (in-window replies) | Replying within 24h of a customer's message | In-window |
| Utility | Order updates, reminders, confirmations | Low |
| Authentication | OTPs and login codes | Low |
| Marketing | Promotions, offers, re-engagement | Highest |
The rate is set by your customer's country, not yours; and message categories are set by the template you use, not by us. To estimate your own monthly message cost, use the calculator — it applies Meta's current rates so you see a real number.
Official Meta Billing Notice: Meta uses per-message billing (effective since 1 July 2025). From 1 October 2026, replies sent inside the 24-hour customer service window are charged at the utility rate after the first 1,000 free service messages a month per number. Meta charges your connected WhatsApp Business Account directly with zero intermediary surcharge.
Yes. The Starter plan is free for your first agent, with no credit card required — you get the full inbox, all channels, Coexistence (“keep your number”), campaigns and the flow builder. You only start paying when you add a second agent ($10/mo each) or move up to a plan with AI Chat or Calling. Meta's message charges still apply on any plan.
If you want your team to share one WhatsApp number, start free on Starter. If customers ask the same questions all day, take AI Chat. If they call as well as message, take AI Chat & Voice. If you want calls answered when nobody is free, take AI Complete.

We'd rather you know before you buy. Omni Chat Stack doesn't yet report campaign delivery, read or reply metrics; the shared inbox doesn't yet have internal notes, agent-to-agent transfer, roles, or saved replies.
No campaign delivery / read / reply metrics yet (simple broadcast execution and logs are supported).
Shared inbox: no internal notes, agent transfer, roles, or saved replies yet (auto-assignment and shared threads are live).
WhatsApp Calling covers inbound and outbound calls; outbound calls need the customer's call permission, as Meta requires.
AI Chat covers English, Urdu, Roman Urdu, Arabic, Spanish, and Portuguese across both Tier 2 and Tier 4.
Quick, honest answers to help you evaluate your WhatsApp Business API costs.
