How to estimate the costs for a Business-initiated or an User-initiated conversation?

WhatsApp Business Platform: Comprehensive Pricing User Education Guide (2024-2025)

In Short
As of July 1, 2025, WhatsApp charges businesses per delivered template message, not per 24-hour conversation. Replies to customer-initiated messages stay free for 24 hours, and utility templates sent inside that window are free. Marketing and authentication templates are charged per message.

Introduction

The WhatsApp Business Platform is undergoing significant pricing updates aimed at improving transparency, aligning with industry standards, and optimizing business messaging costs. Businesses must adapt to these changes to ensure cost efficiency and maximize engagement.
Starting July 1, 2025, every business-initiated message will be individually charged. Businesses will no longer be billed per 24-hour conversation window. Each delivered template will incur a separate charge, even within the same session.
This guide covers:
  1. Per-Message Pricing (PMP)
  2. Types of conversations and their cost structures
  3. Authentication-International Rates and how they impact pricing
  4. Free Entry Point Conversations and their advantages
  5. Timeline of pricing updates and how businesses should prepare
  6. Best practices to optimize messaging costs and maximize ROI
  7. Edge cases, special scenarios, and how to handle them effectively
  8. Updated rate cards and resources for pricing reference
This document aims to be a one-stop resource for businesses using WhatsApp for customer engagement, helping them understand and strategically manage their messaging expenses.

WhatsApp PMP Pricing Model

WhatsApp has historically used a Conversation-Based Pricing (CBP) model, where businesses are charged per 24-hour conversation window rather than per message. However, in 2025, WhatsApp will shift to a Per-Message Pricing (PMP) model, which will charge businesses per delivered template message instead of per conversation.
Understanding the model is essential for businesses to adapt their communication strategies effectively.

Per-Message Pricing (PMP) – Starts July 2025

  1. Before July 1, 2025: Utility template messages were chargeable even when sent within an open 24-hour user-initiated window.
  2. After July 1, 2025: Utility templates are free if sent within the 24-hour of a user-initiated message. This is a new benefit, not a continuation of the earlier pricing.
How PMP Works:
  1. Businesses will be charged per delivered template message rather than per 24-hour conversation session.
  2. Non-template messages will still be free within a 24-hour customer service window.
  3. Utility template messages sent within 24 hours of a user-initiated message will be free starting July 1, 2025.
Key Takeaway
PMP aligns pricing with individual message delivery, making it more predictable for businesses sending outbound messages.

Types of WhatsApp Conversations & Billing Structures

WhatsApp classifies conversations into four distinct categories, each with different pricing and rules:

1. User-Initiated Conversations (UIC) (Service Conversations)

A User-Initiated Conversation (UIC) occurs when a customer messages the business first.
  • Businesses can respond for free within 24 hours.
  • If the business does not respond within 24 hours, it must use a paid template message to continue the conversation.
Example: User-Initiated Conversation
TimeActionCharge
Monday, 11 PMA customer sends a message to a business.
Tuesday, 5 AMThe business replies within 24 hours.Free
Tuesday, 3 PMThe business sends another message (UIC window open until Tuesday, 11 PM).Free
Wednesday, 2 PMThe customer replies; the business can continue with normal messages until Thursday, 2 PM.Free

2. Business-Initiated Conversations (BIC)

A Business-Initiated Conversation (BIC) occurs when a business starts the conversation by sending a pre-approved template message.
  • The business is charged as soon as the template message is delivered.
  • If the customer responds within 24 hours, the conversation remains open and free.
  • If the business wants to send another message after 24 hours, it must send a new template message, which incurs another charge.
Additional Case: What if the customer doesn't respond and the business wants to send another template within 24 hours?
If the customer does not respond, the business may still send additional templates within 24 hours of the first message. The charge will depend on whether the new template is from the same category or a different category:
  • The business sends a template of the same category within 24 hours → Does not incur any additional charge.
  • The business sends a template of another category within 24 hours → Opens a new conversation window for the new category and incurs a separate charge based on the template category.
Example Scenario:
TimeActionCharge
Monday, 10 AMThe business sends a marketing template, opening a paid marketing conversation window.Charged
Monday, 3 PMCustomer has not responded; the business sends another marketing template (same category within 24 hours).No additional charge
Monday, 5 PMThe business sends an authentication template (different category), opening a new conversation window.Charged
Key Takeaways:
  • If sending multiple templates within 24 hours, keeping them within the same category avoids extra charges.
  • Switching to another template category within 24 hours starts a new conversation and incurs a charge for the new category.
  • If the customer responds, all further messages are free within the 24-hour session window.
Example: Business-Initiated Conversation
TimeActionCharge
Monday, 9 AMBusiness sends a marketing template message.Charged for 1 BIC
Monday, 11:30 AMCustomer responds; the business can continue messaging within 24 hours.Free
Tuesday, 10 AMThe business responds after 24 hours, starting a fresh BIC session.New charge

3. Free Entry Point Conversations

When a user initiates a conversation by clicking a WhatsApp Ad or a Facebook Page CTA, a 72-hour free messaging window begins. Learn more
  • First 24 hours: You can send free-form messages or templates, both are free.
  • Next 48 hours: You can send only template messages, still without charge.
This gives businesses extended time to engage without cost, although the type of message allowed depends on the time window.
Key Benefits:
  • A free entry point conversation lasts 72 hours, eliminating conversation charges during this period.
  • It closes all other active conversations, allowing businesses to send messages without additional charges.
Example: Free Entry Point Conversation
TimeActionCharge
10 AMA customer clicks a WhatsApp Ad and sends a message.
Until 10 AM next dayBusiness can reply with non-template messages only (24-hour window).Free
10 PMBusiness responds with a template message; the free entry point conversation begins.Free
Next 72 hoursThe business can send any template message.Free
