Four flexible plans covering WhatsApp, webchat, Facebook, Instagram and email. Start free with your first agent, scale at a flat price per agent as your team grows and pay Meta's message rates directly, with zero markup from us.
Whether you are on our Free Starter tier or scaling a large support team, every plan includes our complete suite of core omnichannel capabilities:
No. OmniChatStack adds 0% markup on WhatsApp messages. Meta charges you directly for the messages you send, at Meta's own published rates, based on message category and the recipient's country. We never add a percentage on top — you pay our flat per-agent plan price, and Meta's message rate, and nothing else.
This is the number to check with any WhatsApp provider. Many Business Solution Providers quietly add a markup — a percentage on top of Meta's rate, a per-message surcharge, or a bundled “messaging credit” that costs more than Meta charges. At scale, even a 15–20% markup adds up fast.
With OmniChatStack, the message rate you pay is Meta's rate. Full stop.
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 bills WhatsApp messages per message, based on the template category — marketing, utility, or authentication — and the recipient's country. Replies you send within the 24-hour customer service window are free. Marketing messages cost the most; utility and authentication cost significantly less. Meta charges your connected WhatsApp Business account directly, at its standard rates.
| Category | What it's for | Cost |
|---|---|---|
| Service (in-window replies) | Replying within 24h of a customer's message | Free |
| 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) and publishes rate updates quarterly (January, April, July, October). Only in-window customer service replies within 24 hours are free. 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.
Unlike typical SaaS trials that expire after 14 days or disable core inbox tools, our Starter tier is free permanently for your first agent. You get full access to WhatsApp, Instagram, Facebook Messenger, email, and live website chat without artificial barriers.
All four plans include the same core inbox — every channel, Coexistence, shared team inbox, campaigns and flows. They differ only in two add-ons: AI Chat and inbound WhatsApp Calling. Starter has neither. AI Chat adds the chatbot. Voice Ready adds calling. AI Chat & Voice adds both. Pick by whether you want AI, calling, or both.
Free 1st agent. All channels, coexistence, broadcast campaigns & visual flow builder.
