WhatsApp chatbot cost has two layers — Meta's messaging fees and your platform subscription. How each works, and how to estimate your real monthly total.
A WhatsApp chatbot has two cost layers: (1) Meta's WhatsApp Business Platform messaging fees, charged per conversation/message by category and country, and (2) your chatbot platform's subscription. SimplyBoost's platform fee is flat — $39/$89/$169 a month — with WhatsApp included from the Growth plan; Meta's messaging fees are separate and billed by Meta.
WhatsApp chatbot pricing confuses a lot of buyers because two different bills are involved. Here's how each works so you can estimate your real total.
Layer 1 — Meta's WhatsApp Business Platform fees
Meta charges for messaging on the WhatsApp Business Platform. The model has shifted over time (conversation-based, then per-message for certain categories) and rates vary by message category — service, marketing, utility, authentication — and by destination country. Always check Meta's current published rates for your country, because they change.
- Service/customer-initiated messages within the 24-hour window are the cheapest (often free up to a monthly allowance).
- Business-initiated (marketing/utility/authentication) template messages cost more and vary by country.
- These fees are billed by Meta, not by your chatbot vendor.
Layer 2 — your chatbot platform subscription
This is what you pay the software that runs the AI agent. Models vary wildly — per-resolution, per-seat, per-conversation, or flat. SimplyBoost is flat: $39 Starter, $89 Growth (WhatsApp included), $169 Pro — no per-conversation platform fee. See full pricing → and the platform pricing comparison →.
Estimating your total
- Estimate monthly WhatsApp conversations and their category mix (mostly service? some marketing?).
- Look up Meta's current rates for those categories in your country → that's layer 1.
- Add your platform subscription → that's layer 2.
- Watch for platform per-conversation fees that stack on top of Meta's — that's the hidden double-charge to avoid.
Frequently asked questions
Is WhatsApp Business Platform free?
The platform access is free to set up; Meta charges for messaging by category and country, often with a free allowance for customer-initiated service conversations. Your chatbot software is a separate subscription.
Does SimplyBoost charge per WhatsApp conversation?
No — the SimplyBoost platform fee is flat ($39/$89/$169). Meta's own messaging fees still apply separately and are billed by Meta.
What's the cheapest way to run a WhatsApp chatbot?
Keep most conversations customer-initiated (cheapest Meta tier), and pick a flat-priced platform so success doesn't inflate your software bill. Per-conversation platform pricing on top of Meta's fees is the expensive combination.
The short version
WhatsApp chatbot cost = Meta's messaging fees (per category/country, billed by Meta) + your platform subscription. Pick a flat-priced platform to keep the second layer predictable. See SimplyBoost pricing →.
