Clients paying late? Let an AI agent chase your invoices, you send
Late invoices eat your Friday. An AI agent keeps the list, drafts a polite reminder on each due date, and brings it to you to send. You keep the client.
Late payers cost you twice: the money, and the hours spent chasing it. Hand the chasing to an AI agent. It keeps the list of open invoices, and on each due date it brings you a polite reminder, ready to send. You read it, change what you want, and send it yourself. The quickest way to get the agent is HostNest, set up for you in about 10 minutes; or use the steps below with an agent of your own.
Why does chasing invoices take so long?
Because every reminder is a small decision: is it time, how firm, which client. A tradesperson put it plainly: "It feels like i'm spending my entire friday afternoon just sending follow-up emails and texts instead of working." The fix is a fixed schedule, so nobody has to decide each morning, and a draft that's already written when the day comes.
Don't have an AI agent yet?
The quickest way is HostNest, a team of Claude agents. You sign up yourself, and the rest comes ready: your own server in the EU (a computer that's always on), the agent, and its wiring. It takes about 10 minutes, most of it the server being built:
- Account: your email (we send you a 6-digit code) or Google.
- Free trial: 7 days free.
- Telegram: a few taps create your bot. The bot is yours.
- Claude: while your server is built, you read four safety rules. Then you sign in to your paid Claude plan (Pro, Max, Ultra or Team) and paste back one code.
- Live: open your agent in Telegram and send it the message below.
After that, the upkeep is handled for you. Updates install themselves overnight, a failed one rolls back on its own, and the server is backed up daily. A check your agent sets keeps its time through restarts and updates. Get your agent on HostNest
Do I need to code? No. You talk to your agents in Telegram. How long does it take? About 10 minutes, most of it the server being built. Will it do things without asking? It checks with you before anything goes out or costs money, unless you tell it it doesn't need to. Is my stuff safe? It runs on your own private server in the EU, with your own Claude login, and it's backed up daily.
Already running an agent of your own? The steps below work on any agent that keeps notes and can keep a daily check.
What does the agent do?
- It keeps the list: each open invoice with the client, the amount, the due date and what's been sent.
- It follows one schedule: a friendly note 3 days before the due date, a reminder on the day, then a firmer one each week.
- It drafts each reminder in your voice, and brings it to you in Telegram that morning, ready to copy.
- You send it from your own email or phone, and tell it when a client pays. It moves them off the list.
How do I set it up?
- Send your agent your open invoices: client, amount, due date, and how you usually reach them. A photo or a forwarded invoice works.
- Send it the message below.
- It sets itself a check for every morning at 9:00.
- Each morning, read what's due, change what you want, and send it yourself.
- When a client pays, tell it "paid".
What message do I send my agent?
Copy this, fill in the brackets, and send it to your agent:
You keep my unpaid invoices. Here they are: [client, amount, due date, how I reach them].
Every morning at 9:00, check what's due and draft the reminders for me to send:
3 days before the due date: a friendly heads-up.
On the due date: a short, polite reminder with the amount and how to pay.
Each week after: a firmer note. After three, tell me to call them instead.
Write them the way I write: [paste one of my emails].
Never send anything yourself, and never threaten. I send every message.
When I say a client paid, take them off the list.
Set this up as a check that runs every morning at 9:00.What won't the agent do?
- It won't send, call or charge anyone. It checks with you before anything goes out or costs money, unless you tell it it doesn't need to.
- It won't see your bank or your accounting tool unless that connection is built on request, with your own login. Until then, it knows what you tell it.
- It isn't legal advice. Liens, late fees and contract terms differ by place: check yours before you put them in a reminder.
