Meet Bill.
Bill is a friendly AI koala — tireless, always-on, and obsessed with making invoicing effortless. Think of Bill as your personal billing assistant who never takes a break, never forgets an invoice, and never complains about chasing payments.
The Story
BillKoala was born out of frustration. We spent years watching small businesses and freelancers waste hours every week on invoicing — creating PDFs, looking up client details, copy-pasting tax IDs, chasing overdue payments. No matter how good the tools, the fundamental problem remained: invoicing felt like a chore.
So we asked: what if you didn't have to create invoices at all? What if you just told someone what to bill, and they handled everything? That someone became Bill — an AI agent that lives in your chat apps, reads your email, and sends invoices the moment you mention them. Built in Vienna, powered by modern AI.
Our Mission
We believe invoicing should take 10 seconds, not 25 minutes. Our mission is to make billing busywork disappear — not by eliminating the data, but by eliminating the manual labor. Every hour your team saves on admin is an hour spent growing your business.
Built for Compliance
BillKoala is built with compliance at its core — GDPR, GoBD, and Austrian tax law. Your invoices, client data, and financial records all live on EU-hosted infrastructure. Secure, compliant, and designed for businesses that take data protection seriously.
