WhatsApp message fees & payment method

WhatsApp message fees are charged by Meta directly to your business, separate from your Zymbler subscription. Zymbler doesn't mark up, resell, or pass through messaging costs. Two invoices, two relationships.

Meta prices WhatsApp per message, not per conversation, and bills your business directly.

• Replies are charged from 1 October 2026. When a customer messages you, a 24-hour customer service window opens. Replies inside it, including the agent's, are charged at the utility rate for the customer's country (they were free before that date). Replies after someone messages you from a Click-to-WhatsApp ad stay free for a while. Plan on 72 hours: Meta's developer page says up to 7 days, and the WhatsApp Business site says 72 hours.
• Marketing templates are charged, for example a broadcast to your list, except inside a free entry point window.
• Utility and authentication templates are charged, with lower rates at higher volumes. From 1 October 2026 that includes utility templates sent inside the window.

Rates vary by country and change over time, so rather than quote numbers that go stale, see Meta's own pricing page: Meta's WhatsApp pricing.

1. Go to WhatsApp Manager.
2. Switch to the Business Account that owns your WABA, if you have multiple.
3. Sidebar → Payment settings (sometimes under "Settings").
4. Add payment method → enter card details, billing address, and your tax ID (such as a GST or VAT number) if applicable.
5. Save. Your WABA can now send the templates Meta charges for.

• You get two invoices. One from Zymbler (your subscription, monthly/annually). One from Meta (WhatsApp message fees).
• You own the WABA. If you ever stop using Zymbler, your WhatsApp number, templates, and quality rating stay with your business — there's no lock-in.
• You see usage in Meta's tools. WhatsApp Manager shows messages, costs, and templates. Zymbler shows you everything that happened in the conversations (which is what you actually care about for sales).
