BillFold Pro is a Python 3.9+ command line tool for Windows, macOS and Linux. It detects Alipay, WeChat Pay and bank export CSVs, handles GBK and UTF-8, and normalizes them into date, amount, direction, counterparty and category fields. It writes monthly and category reports in Markdown. A browser trial parses samples locally with no upload, and a sample CSV is available to download.
Pro is a one-time £39 purchase (about $5.50) with no subscription, including source and a commercial license for one person or studio. Checkout is not yet connected, so Pro is not yet purchasable.

Freelancers who export messy payment CSVs from Alipay and WeChat for tax season spend hours cleaning columns. BillFold turns that cleanup into a command line tool, with a browser trial to try it first.
