AI agent

The AI invoicing assistant that does the work

Billy includes an AI agent that handles the routine work around your invoices. It drafts invoices from plain text, emails them to clients, sets up recurring invoices, and automatically sends payment reminders (Mahnungen) for overdue invoices — right inside the app you already work in.

That is the difference from classic invoicing software: Billy does not wait for you to trigger every task, it works in the background on your rules.

What the AI agent does

You tell Billy in plain language what to do — or you set a rule once and the agent does it again and again. Concretely:

  • Draft invoices from plain text — even without saved products
  • Automatically create and send recurring invoices on schedule
  • Monitor overdue invoices and send payment reminders and Mahnungen
  • Email invoices and quotes to clients on request
  • Set up recurring invoices Billy generates automatically
  • Configure automatic payment reminders (Mahnungen) for overdue invoices
  • Tell you who still owes you money
  • Find, create, and update clients
  • Mark invoices as paid and update statuses
  • Report revenue stats, top clients, and breakdowns on request

How the agent works

You chat with the assistant in natural language (German or English), or you schedule tasks as one-off or recurring runs. In the background, Billy generates recurring invoices and sends payment reminders automatically on the schedule you set.

You stay in control: actions that change or delete data require confirmation, and the agent never fabricates data — it works only with what is actually in your account.

Why this matters for small businesses

Chasing open invoices and creating recurring invoices costs freelancers and small businesses time every week. Billy’s AI agent takes on exactly those tasks — so you get paid faster and can focus on your business instead of admin.

Frequently asked questions

What is an AI invoicing assistant?
An AI invoicing assistant is a software agent that handles routine invoicing work — such as drafting invoices from plain instructions, sending recurring invoices on schedule, and automatically sending payment reminders for overdue invoices. Billy’s AI agent is built directly into the invoicing app.
What exactly can Billy’s AI agent do?
Billy’s AI agent drafts invoices from plain text, emails them to clients, finds and creates clients, marks invoices as paid, sets up recurring invoices, tells you who still owes you money, and configures automatic payment reminders (Mahnungen). It can also report revenue stats and breakdowns.
Does the AI agent create invoices without my involvement?
You stay in control. Routine jobs like recurring invoices and reminders run automatically on your rules, and any action that changes or deletes data requires confirmation. So Billy automates the work without taking authority over your data away from you.
Does the agent write payment reminders automatically?
Yes. Once you switch reminders on, Billy checks overdue invoices every day and sends payment reminders and Mahnungen automatically on the schedule you set — one of the most time-consuming backoffice tasks.
What language does the assistant respond in?
The assistant always responds in your language — German or English — based on your selected app language.
Is the AI agent included in every plan?
The AI agent is part of Billy. Monthly included usage depends on your plan (Founder, Growth, Pro). Every plan starts with a 7-day free trial.
