Is this your business?

Quote the repair. Chase the payment.

Agentize turns a voice note about the job into an itemised quote from your own labour and parts prices, books the work in, invoices when it's done and follows up the customers who haven't paid, 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
