Is this your business?

Quote it from the ute.

Agentize gives builders & trades a little crew of AI helpers. Say the job into your phone and the Quoter writes an itemised, GST-sorted quote from your own rate card. Then the crew books it in, sends the invoice and chases the money, all in your business's name.

  • Quotes from a 30-second voice note
  • Invoices sent, late payers chased
  • Your prices, your name, nothing sent without your OK
