Billly is the bookkeeping app for freelancers that runs in the background. Pick a folder, paste your OpenAI token once, and you’re done. Billly watches for new PDF invoices, extracts values via OCR + AI, and keeps revenue, expenses, and profit up to date automatically, no spreadsheets, no manual tagging, no “setup rabbit holes”.


Hi Product Hunt, I’m Oliver — I’m building Billly, the laughably easy bookkeeping app for freelancers.
Billly is the bookkeeping app for freelancers that runs in the background.
Pick a folder, paste your OpenAI token once, and you’re done. Billly watches for new PDF invoices, extracts values via OCR + AI, and keeps revenue, expenses, and profit up to date automatically—no spreadsheets, no manual tagging, no “setup rabbit holes”.
Why Billly
Laughably easy: two inputs, then it just works.
Low-effort: OCR + AI auto-extracts totals, taxes, dates, and vendors.
Lightning-fast: trends and totals update seconds after a new PDF lands.
Pricing
Billly is free to download and use. You only pay OpenAI usage (billed by OpenAI),
with a typical benchmark of ~50 invoices ≈ 1 EUR.
Privacy & disclaimer
Your PDFs stay on your machine; only extracted text is sent to OpenAI for value extraction.
Billly is a bookkeeping tool, not tax or legal advice.
Small update I fixed the error for Apple Silicon :)
