WhatsApp July & Aug 2025 invoices clarifications

Objective

This is a temporary KB article meant only for a limited period of time. The aim of this KB article is to give a brief explanation of the manual adjustments and CBP-model charges flowing in WhatsApp customers' invoices for July and August 2025.

Applies To

• Impacted WhatsApp customers

Per message charges adjustments

Due to some issues after the migration from Per Conversations to Per Message model in our rating systems, we had to run some manual calculations and post adjustments to the July & August billing in order to get accurate charges reflected on our customers' invoices. 

How does this reflect on your invoice? 

The adjustment is being posted as one negative or positive charge at the bottom of your invoice representing the full amount to adjust. This will be shown at the bottom of your invoice under the following Product details: 

• WhatsApp fee adjustments
• Platform fee adjustments 

Per conversation charges explanation

For July and August 2025 usage, you might still see some charges related to the old “per conversation” pricing model (CBP). 

These charges are related to conversations opened before 1st July under CBP model. These can either be running for this long as a continuous conversation, or more likely, that a message of the conversation that was sent before 1st July 2025 was not delivered earlier, and WhatsApp is retrying delivery, as it does for any failed messages for 30 days.

In case there are any questions regarding the above, please reach out to your Account Manager or Vonage point of contact.
