Use case
Chase overdue invoices with an AI agent
In shortA collections agent in Vellarin Agents reads your list of unpaid invoices, groups them by customer and days overdue, and drafts a polite reminder for each with the amount and how to pay. It is for small businesses that would rather not spend Friday afternoon chasing payments. Reminders wait for your approval before they go out. Free to start; Pro is US$19 a month.
The problem
Chasing late payers is uncomfortable, so it gets postponed, and every week of delay makes the money harder to collect.
How the agent does it
- Hire an agent and describe the job in one sentence, for example "every week, remind customers with invoices more than 15 days overdue". There is no ready-made template for collections yet; the sentence is enough.
- Give it the invoice list: an export from your accounting tool, a spreadsheet, or QuickBooks or Stripe once connected.
- It lists who owes what and for how long, from most to least overdue.
- It drafts one reminder per customer: polite, specific, with the invoice numbers and amounts from your list.
- You approve, change or reject each reminder; approved ones are sent once.
What needs your approval
Reading and drafting run on their own. Sending an email, posting a message or changing a record in an app waits for your OK: you see exactly what will go out and press Approve, Change or Reject. Nothing is sent before that.
Tell it your payment terms and tone once ("30 days, friendly, no threats") and every reminder follows them.
Which AI and apps it uses
Claude, ChatGPT or Gemini on your computer. Files today; with one-click apps it can read QuickBooks or Stripe and send from Gmail or Outlook after your approval.
Questions
Can it charge a customer's card?
Any payment action in an app is a write, so it waits for your explicit approval. The job described here only drafts reminders.
Will it get the amounts wrong?
It copies amounts from the list you give it and tells you when something is missing. You see every reminder before it is sent.
Can it run on its own every week?
Not yet. Today you start the job with one tap from the agent's card or with a message. Work that starts on its own (at a set time or when an email arrives) is coming soon.
How much does it cost?
Free with one agent on one computer. Pro is US$19 a month (or US$15 a month billed yearly) for unlimited agents on up to 3 computers, with a 14-day free trial and no card to start. The AI itself runs on the subscription you already pay for.
