How it works

Get your first call answered in four steps

  1. Step 1

    Pay

    Subscribe to the plan. Your business opens once the first payment is made.

  2. Step 2

    Set up your business

    In the dashboard, enter your hours and services and connect your Google Calendar.

  3. Step 3

    Forward the calls you miss

    On your own phone, forward missed calls to your callzerus number. Your callers keep dialling your number. The dashboard shows the code for Verizon and T-Mobile and the menu steps for AT&T.

  4. Step 4

    Test it

    Call your mobile from another phone and let it ring. The receptionist answers.

How minutes are counted

  • You never get a surprise bill: the plan has a fixed number of minutes.
  • Minutes are the talk time of answered calls. We add them up over a calendar month and round up to whole minutes.
  • One call can last up to 15 minutes.
  • Demo sessions in the browser do not count.
  • When the minutes run out, the receptionist tells callers it cannot take the call right now. You can add 100 minutes for $25 for that month.
  • Your dashboard shows the minutes you have left.

If you cancel

  • You can leave any time, and you keep what you paid for. The paid month runs to its end. Then the receptionist stops answering.
  • Your number is kept for 30 days in case you come back.
  • Your dashboard stays readable.
  • Call transcripts and summaries are deleted 90 days after the call.
  • There is no refund for a started month.

Questions

Questions plumbers and other trades ask first

What if it cannot answer a question?

It notes the question for you in the dashboard. Your answer is used on later calls.

What happens if I run out of minutes?

The receptionist tells callers it cannot take the call right now. You can add 100 minutes for $25 for that month. Your dashboard shows the minutes you have left.

Is the call recorded?

Does it work with my software?

If it is not on the list, tell us which tool you use. This is for paying customers. The tool needs an official connection, such as an API or an MCP server.
