AI Payment Reminder Calls
Get Paid Faster, Without an AR Team
AI calls your own customers about upcoming or past-due invoices, sends a secure payment link via SMS, and routes anything complex to your team. First-party reminders only — not third-party debt collection.
What it does
Phone Stack's payment-reminder workflow uses an AI voice agent to call your customers about their own invoices, subscriptions, and balances — references the specific amount and due date, offers a secure Stripe pay-link via SMS, and routes anything complex to a human on your team.
This is built for first-party outreach: your business calling your customers. It is not built for third-party debt collection on behalf of other parties.
Important — what this is and isn't
- • Designed for first-party payment reminders only.
- • Not designed or marketed as third-party debt collection software.
- • Phone Stack provides outbound calling tools. You are responsible for your own TCPA, state, and industry compliance posture — including consent, opt-outs, and recording disclosure.
- • If your use case touches debt collection on behalf of others, talk to your counsel before deploying.
