Everything Billy does for you
Billy is the AI invoicing app for freelancers: beautiful where clients see it, effortless everywhere else. Tell the assistant what to bill — it handles the rest, and you approve.
The AI assistant
Billy's core — and what no other invoicing tool in the German-speaking market offers like this: an assistant that actually does the work, not just reads receipts.
- An invoice from a sentence: "Bill Anna €1,200 for the March workshop" — ready for your review.
- Send it by email — on your confirmation.
- Answer questions like "Who still owes me money?" in plain language.
- Set up recurring invoices and automatic payment reminders.
- You approve every data-changing action — Billy never acts on its own.
Invoices & documents
- Five professional templates with a live preview as you type
- Quotes and credit notes (Storno)
- Recurring invoices on a schedule
- Your own logo, colors and layout
- Download as PDF or send directly by email
Automatic payment reminders
Billy keeps an eye on open invoices and sends payment reminders on the schedule you set — included from the entry plan, not locked behind an expensive tier.

What Billy is (deliberately) not
Billy is not accounting software: no EÜR profit statement, no VAT filing via ELSTER, no DATEV export. If you need that, we're honest about it — our invoicing-software comparison shows which tool fits better.
