Automate client onboarding in OpenAI Agents SDK

Stop manually copying data into your accounting platform. Your agent uses `create_client` to push records directly into your database the moment a contract is signed. Keep your CRM and billing in sync. The `list_clients` tool lets your agent verify existing records before creating duplicates.

Generate invoices using OpenAI Agents SDK

Send bills as soon as work finishes. Your agent calls `create_invoice` to generate line items based on your project logs. Check status updates instantly. Use `get_invoice` to confirm details before you trigger a payment request.

Maintain billing accuracy with this MCP Server

Update invoice states without manual clicks. Use `update_invoice` to shift records from draft to sent status programmatically. Correct errors before they reach the client. The `update_client` tool ensures contact info stays current as your business evolves.
