Hi VAPI Support Team, We’re currently using your service and have built an AI voice agent to handle calls. We have a few questions regarding client billing and security: Client Billing: Is it possible for our clients to create their own accounts and link their credit cards so they are billed directly based on usage (e.g., minutes used)? Agent Security: We want to prevent clients from downloading or accessing the AI agent’s prompts and workflow charts while ensuring they can fully utilize the agent. Could you confirm if these options are supported or if you have recommendations to help us implement these features? Thanks in advance for your guidance!

Hi there! 😊 I'm glad to hear you're using our VAPI service for your AI voice agent! Let me address your questions regarding client billing and agent security: ### Client Billing Yes, your clients can create their own accounts and link their credit cards for direct billing based on usage. Here's how it works: 1. **Account Creation**: Clients can create their accounts and will receive complimentary credits to start. 2. **Linking Credit Cards**: They can link their credit cards through the VAPI dashboard for automatic billing based on usage. 3. **Pay-As-You-Go Model**: Once the initial credits are used, they can purchase additional credits to continue using the service. For more details, you can check out the [Billing FAQ](https://docs.vapi.ai/billing/billing-faq). ### Agent Security To ensure your clients cannot download or access the AI agent’s prompts and workflow charts, VAPI has several security measures in place: 1. **Isolated Virtual Private Clouds (VPCs)**: Your AI models are hosted in secure, isolated environments, preventing unauthorized access. 2. **No Direct Access**: Clients cannot directly access the AI models or workflow charts, ensuring that sensitive information remains protected. 3. **On-Prem Deployments**: For organizations with strict data security needs, we offer on-premise deployment options. For more information on our security measures, you can refer to the [Security and Privacy](https://docs.vapi.ai/security-and-privacy/pci) documentation. If you have any further questions or need assistance with implementation, feel free to ask! I'm here to help! 😊 Sources: - [Billing FAQ](https://docs.vapi.ai/billing/billing-faq) - [Security and Privacy](https://docs.vapi.ai/security-and-privacy/pci)

Thank you for the clarification! I just want to confirm—if I create an agent and my clients use it, will I not be charged at all? Will all charges be directly billed to my clients, or is there any cost I should be aware of on my end? Looking forward to your response!

@bekzodbekturgunov If you add your client’s billing details to your org, your client card will be charged for each call. If you add your client to their org, they can view the assistant prompt and other settings.
