Run the reminder sequence on every ageing invoice, handle the standard replies, and hand the owner a call list of the accounts that actually need one.
An AI agent for chasing unpaid invoices is a 24/7 digital assistant that watches your ageing report, sends the reminder sequence on schedule, answers the routine replies, and tells you which accounts are worth a phone call. It stops a 30-day balance from quietly becoming a 90-day balance when nobody in a two-person office has time to work the ageing list. The agent does not take or move money. It sends the customer the payment link you already use, whether that is QuickBooks Payments, Stripe or your card portal, and the payment happens entirely inside your existing system. What it removes is the part that never gets done: the second reminder, the third, the polite escalation, and the discipline of doing it on the same day of the week every week regardless of how busy the schedule is.
Works the ageing list, escalates by age, and surfaces who to call.
Reads the ageing report and picks up each invoice as it crosses a threshold
Sends reminders at 7, 14 and 30 days with the invoice attached and your payment link
Shifts tone as the balance ages, from a friendly nudge to a formal notice
Answers routine replies — resend the invoice, wrong contact, awaiting a purchase order
Escalates disputes and 60-day-plus balances to the owner with a short summary
Logs every attempt, reply and outcome against the customer record
Receivables do not go bad because customers refuse to pay. They go bad because the second reminder never went out. In a small contracting office the person who would send it is also answering the phone and dispatching, so the ageing report gets worked in the quiet weeks and ignored in the busy ones — which are exactly the weeks the balances grow. A scheduled agent does not have a busy week, and it hands back a two-name call list instead of a twenty-two-line report.
A simple, three-step flow.
The agent reads open invoices and their ages from your accounting or field-service system on a set schedule, and picks up anything that has crossed a reminder threshold.
It sends the reminder for that stage with the invoice and your existing payment link, then handles the standard replies — a resend, a corrected contact, a request for a purchase order number.
Disputes, promises to pay and balances past your escalation age go to the owner or office manager with a short summary and a suggested next step.
A realistic use case with concrete timing and output.
Scenario: a commercial HVAC contractor carrying $86,000 in receivables, $31,000 of it past 60 days, with one office administrator covering dispatch and billing. Monday 8am the agent works the list. Fourteen invoices at 7 days get a first reminder with the PDF and the payment link. Six at 30 days get a firmer note naming the amount and the original due date. Two property managers at 75 days get a summary and a line saying the owner will call Thursday. By Wednesday nine have paid through the existing link, three have replied asking for a purchase order number the office never received, and one has disputed a filter charge. The owner's Thursday call list has two names on it rather than twenty-two.

Sends short text reminders to residential customers who never open billing email.
Sends the email sequence from your billing address and reads replies so the thread stays in one place.
Six practical scenarios that this AI agent excels in.
Common questions about using the AI agent in workflows.
An AI agent for chasing unpaid invoices is a 24/7 digital assistant that watches your ageing report, sends the reminder sequence on schedule, answers the routine replies, and tells you which accounts are worth a phone call. It stops a 30-day balance from quietly becoming a 90-day balance when nobody in a two-person office has time to work the ageing list. Unlike a collections agency or a one-off reminder feature in your accounting software, it runs the whole sequence, handles the replies, and escalates to a person at the point where judgment is needed.
No. Agentplace agents cannot take or move money, and this one does not try. It sends the customer the payment link you already use — QuickBooks Payments, Stripe, your card portal — and the customer pays through that system exactly as they would today. The agent then reads the paid status and stops chasing. All reconciliation stays in your accounting software.
Consistency and early contact do most of the work. A reminder at 7 days is routine and nobody takes offense; a first contact at 75 days feels like an accusation. You write the wording for each stage, the agent sends it on time, and anything that turns into a real conversation is escalated to you rather than argued by an automated message.
The sequence stops immediately for that invoice. The agent captures what the customer said, attaches it to the job record, and passes it to the owner or office manager with the job history. It does not negotiate, discount or promise a credit — that is a decision for a person with the authority to make it.
Yes, and that is one of the most useful cases. When a reply says the invoice cannot be processed without a purchase order number, the agent asks for the number, records it against the invoice, resends with it included, and restarts the clock. Many 60-day commercial balances are nothing more than a missing reference.
Yes. It checks payment status against your accounting system before every send, so an invoice paid on Sunday is not chased on Monday. Partial payments are recognized too, and the remaining balance carries on at the correct stage of the sequence rather than starting again.
You set exclusions — accounts on an agreed payment plan, a customer in a live dispute, jobs under a certain value, or any account you flag by hand. The agent skips those and lists them separately so you can see what is being held back and why.
Run the reminder sequence on every ageing invoice, handle the standard replies, and hand the owner a call list of the accounts that actually need one.
