Collections

Your AI collections team

Overdue accounts need a conversation, and no team has the hours to have one with every customer. Sono calls the whole book from day three, adapts to what each customer can actually pay, agrees a plan inside your policy, and hands anyone who needs a person to your team.

Fully-custom AI Assistants that
handle tasks end-to-end

Work your outbound call list at scale, and answer every incoming call — without adding headcount.

Outbound

Work every list your team can't get to

Overdue accounts, lapsed customers, cold leads, fresh signups — Sono calls all of them at scale, in your customer's language, and logs every outcome.

Inbound

Answer every call, 24/7

Zero wait time, zero missed bookings. Sono picks up when your team can't — overnight, during peak hours, or whenever you decide.

  • → Book service appointments end-to-end
  • → Triage and route urgent calls to the right person
  • → Handle FAQ and routine support inquiries
  • → Capture caller details for follow-up when humans can't pick up

Outbound use cases

Outbound calls that
pay for themselves

Hand Sono a list and a goal: overdue invoices, accounts in arrears, customers who went quiet. It calls in your voice, in your customer's language, agrees the next step, and logs every result.

Catch overdue invoices at day three, not day sixty

Sono reads your overdue ledger, calls each account inside the reminder window, clears whatever is blocking payment, and secures a dated commitment. Disputes go to your billing team the same day.

Turn arrears into payment plans customers keep

Sono works accounts already in arrears: it states the balance, listens to the customer's situation, and offers a payment plan inside your policy that it has checked they can afford. Hardship, disputes and vulnerability signals go to a person on your team, with the transcript attached.

Win back the customers who quietly stopped buying

Point Sono at the customers who haven’t been back in a year. It calls each one with a warm check-in and a reason to return, and books the visit or reorder before the call ends. Every outcome writes back to your CRM.

Frequently asked questions

Sono is an AI phone assistant that answers calls in a human-like manner and handles routine requests 24/7. It uses advanced natural language processing to understand customer needs, provide relevant information, and complete tasks like booking appointments.

We connect Sono to your website and information, test responses, and you set call forwarding (typically minutes). The entire onboarding process takes less than an hour and requires no technical skills from your team.

Yes—calls only go to Sono if you can't answer. You have full control over when and how Sono handles calls. Many teams use Sono as a backup during busy times or outside business hours.

You decide. Many teams prefer to confirm appointments themselves – Sono collects a complete request for follow-up. Alternatively, you can enable direct booking where Sono finalizes appointments in your calendar automatically.

Yes. Sono runs outbound at any volume: payment reminders from day three overdue, collection calls on accounts in arrears, and reactivation calls to customers who went quiet. It calls in the customer's language, agrees the next step, and writes the outcome back to your system.

They get one. Sono hands over to your team by warm transfer or scheduled callback whenever a customer asks, and routes disputes, hardship and anything outside its mandate to a human automatically, with the transcript attached.
