AI Agent
Hi, this is Alex calling on behalf of Bright Solutions regarding invoice #3047 for $1,850, which went overdue on March 10. I wanted to confirm payment timing.
Customer
Right, I meant to handle that. Can we do Friday, March 20?
AI Agent
Absolutely. I'll log a promise-to-pay for Friday, March 20. I can also resend the payment instructions saved on the invoice.
Customer
Yes please, send those to my email on file.
What gets logged

How automated overdue invoice follow-up works
Most teams start with a simple four-touch cadence: Day 1 reminder, Day 7 follow-up, Day 14 escalation, and Day 30 final notice. The goal is consistent, polite outreach that confirms payment timing, logs promise-to-pay dates, and hands off exceptions cleanly.
Day 7
Second follow-up with commitment
Reference the first attempt, request a firm timeline, and log a promise-to-pay date when possible.
Day 14
Escalation call
Raise urgency, surface blockers, and flag anything that needs a person to step in.
Day 30
Final notice and next steps
Issue final outreach, confirm whether payment is imminent, and route unresolved accounts to your team.

Frequently Asked Questions
An AI invoice agent is a voice assistant that makes polite, automated reminder calls on overdue invoices, captures payment commitments, and logs outcomes for your team.
The agent automatically begins follow-ups once an invoice is overdue, confirms payment timing, and schedules the next touch until it is resolved.
It is automated invoice follow-up via AI voice calls. Most teams use it for routine outreach and keep people involved for disputes, sensitive accounts, or relationship-heavy conversations.
Yes. The agent records promised payment dates, notes blockers, and keeps the invoice status up to date so the next step is clear.
Yes. The agent uses your existing invoice data and writes outcomes back to the customer record, so you do not need separate spreadsheets.
An AI late payment follow-up agent is an automated assistant that contacts customers after invoices are overdue, follows a repeatable reminder cadence, and records every outcome in your workflow.
It helps by calling sooner, following up consistently, capturing clear payment commitments, and escalating at the right time so invoices do not sit untouched.
A practical baseline is Day 1 reminder, Day 7 follow-up, Day 14 escalation, and Day 30 final notice with handoff options. The agent follows a proven cadence and adapts based on invoice context and customer history.
Keep the message neutral and specific: reference the invoice number, amount due, and payment date, then ask for a confirmed payment timeline and offer help with billing details.
For many small teams, yes for day-to-day follow-up. Most teams still keep humans for exceptions, disputes, and high-risk accounts while AI handles routine outreach.
When a customer does not answer, the agent leaves a professional voicemail referencing the invoice number, amount, and a callback prompt. The voicemail is logged and the next retry is scheduled automatically.
The agent is finely tuned and draws on your product and service descriptions, invoice details, and customer context to personalize each call professionally. It adjusts tone naturally based on the conversation and invoice history.
Natural, human-like voice is powered by ElevenLabs. Anthropic Claude and OpenAI GPT models support agent reasoning, transcript analysis, summaries, and follow-up intelligence. InvoicifyAI combines those models with your invoice data, call rules, and AR workflow so reminder calls stay relevant, professional, and actionable.
