Side by side
Double-entry accounting with invoices, bills, expenses, inventory, bank transactions and financial reports, also usable headless through its API.
Uses an LLM to read photos of receipts, invoices and PDFs, extracting amounts, dates, merchants and taxes into a searchable table with currency conversion.
Still pre-1.0, AGPL licensed, and it lacks the bank feeds and tax filing integrations of Xero or QuickBooks.
The author calls it early development, it is not double-entry accounting, and extracted figures need checking.
