How credits are used
AI Receptionist deducts one credit per answered call, regardless of how long the call lasts. A 10-second call and a 10-minute call both cost the same: one credit.View your balance
Your account balance and usage breakdown live on the Billing tab in your account. Click the gear icon at the bottom of the sidebar to open Settings. Then choose Billing.Monthly allotment
Your subscription includes a monthly call allotment. This resets on your billing cycle date. Unused credits do not carry over.Per-receptionist billing
Billing scales per receptionist. hyzl gives each receptionist you create its own dedicated phone number, and hyzl bills each added number. There is no cap on how many receptionists you can run.- Per-user. Whoever creates a receptionist pays for it on their own subscription and payment method.
- Deleting decrements billing. Deleting a receptionist releases its number and reduces your bill. Deleting your last receptionist cancels the subscription.
Auto Top-Off
AI Receptionist supports automatic top-off so you never miss a call due to an empty balance:- Open your receptionist’s Settings page
- Find the Automatic Credit Top-Off section
- Turn on Enable automatic credit top-off
- Attach a card with Set Payment Method (or Update Payment Method to change it)
Buy more credits
To buy credits manually, click the Buy Credits button at the bottom of the sidebar.Failed payments
If an auto top-off charge fails, the portal displays a warning banner. The banner warns that future calls may be dropped until you fix the issue. Your balance can reach zero while auto top-off is turned off, or while its last charge has failed. In either case, the portal kills incoming calls mid-call with an error message instead of answering them. The banner shows a specific failure reason so you can take the right action:
Each failure has its own dismiss state. Once you fix the underlying issue, the banner stays gone for that incident. A fresh failure shows the banner again, so you do not miss it. An example is a new declined charge a week later.
