Problem
Freelancers and accountants pile up invoice PDFs with useless export names — scan001.pdf, invoice (3).pdf — and rename each one by hand before filing.
Approach
AutoInvoice Pro reads each PDF's text locally with pdf-parse, then pattern-matches the date, amount, and company name to build a clean filename like 2026-02-22_Company_Total.pdf. Drag a folder in, get a renamed batch out — nothing leaves the machine. The free trial covers five files; a Gumroad license key, verified against Gumroad's own API, unlocks unlimited use.
Tradeoffs
Deterministic text matching, not a language model — scanned or image-only PDFs with no extractable text fail cleanly rather than guessing. Files over 5 MB are skipped in the free tier. Builds are unsigned, so first launch needs a one-time Gatekeeper bypass on macOS.
Outcome
Live as a pay-what-you-want download on Gumroad for Mac and Windows, with a working license-key unlock built on Gumroad's own verification API.
