See [What WhatsApp API Pricing Really Means](/learn/chatsyncs-overview/what-whatsapp-api-pricing-really-means-in-chatsyncs) for the plain-English breakdown, or [Conversation Categories & Pricing](/meta-api/concepts/conversation-categories-and-pricing) for the full API-level rate table. * Meta requires a payment method on file before it lets messages send past the free tier. ## Set it up In [Meta Business Suite](https://business.facebook.com), click your business portfolio name in the top-left switcher, then click the **gear icon** next to it to open Settings. Meta Business Suite business portfolio switcher open, showing the Bengalururent business portfolio with its settings gear icon highlighted Under **Accounts → WhatsApp accounts**, select the WhatsApp Business account you want to bill. Its current **Payment method** (if any) shows on the right. Click **Payment settings**. Meta Business Suite Settings, WhatsApp accounts list with one account selected showing its Account status, Payment method, and a highlighted Payment settings button This opens **Billing & payments**. Under **Payment methods**, click **Add payment method**. You can have more than one card on file — Meta uses whichever is marked **Default**. Meta Business Suite Billing and payments page, Payment methods section showing one existing Visa card and a highlighted Add payment method button, with a Payment activity table below In the **Add payment information** dialog, choose the **Country/region**, **Currency**, and timezone, then click **Next**. Add payment information dialog with Country/region set to India, Currency set to Indian Rupee, timezone set to Kolkata, and a Next button **Location and currency cannot be changed once set.** Double-check both before clicking Next — changing them later means removing the payment method and starting over. On the **Debit or credit card** screen, fill in the **Name on card**, **Card number**, expiry (**MM/YY**), and **CVV**, check the authorization box, then click **Save**. Debit or credit card dialog with Name on card, Card number, MM/YY, and CVV fields, an authorization checkbox, and a Save button Some cards get an error on the first attempt — this is usually the card issuer declining, not a problem with the details entered. Try a different card if one gets rejected; a second card often goes through where the first didn't. **Expected result:** The account's **Payment methods** list shows your new card, and it's ready to be billed for conversations once the free monthly conversations run out. This same **Billing & payments** page also has a **Payment activity** tab, showing every charge against this payment method — useful for checking a charge without leaving Meta Business Suite. Right after saving a payment method, Meta sometimes shows a banner asking for **missing business information** (Legal Business Name, Address, Phone Number, Website). Click it and fill in whatever's requested — Meta won't process billing until that information is complete. ## What's next With a payment method on file, your number can keep sending messages past the free tier without interruption. See [Conversation Categories & Pricing](/meta-api/concepts/conversation-categories-and-pricing) for what actually gets billed, or head back to [How to Connect Your Number to ChatSyncs](/learn/chatsyncs-setup-and-configuration/connect-your-number-to-chatsyncs) if you haven't finished that yet.
