How does billing work?
You buy message credits in advance. Each successful send deducts one credit. Your balance and every movement are visible in the dashboard ledger.
Do I need a WhatsApp Business account?
You connect a WhatsApp number to ZNotice. Once linked, we expose it through the API.
Is there a monthly fee?
No. You only pay for credits and, optionally, the one-time integration service.
What does the integration service include?
For a one-time $20.00 fee we connect ZNotice to your product, implement the send flow and hand over tested code.
