TaxHacker

TaxHacker is a self hosted accounting application that uses large language models to read receipts and invoices and turn them into structured transaction records. It is aimed at freelancers, indie developers and small businesses that want to handle their own bookkeeping without manual data entry. The site describes the product as under active development. Users upload photos or PDFs, singly or in bulk, and the AI extracts dates, line items, vendors and amounts in any language. Foreign currencies are detected and converted using the historical exchange rate for the transaction date, with support for more than 170 currencies and common cryptocurrencies. Categories, projects and fields are fully customizable, and the extraction prompts can be edited so the AI parses extra fields or assigns categories the way the user wants. Transactions can be filtered, searched in full text, imported from CSV and exported to CSV for tax preparation. A built in invoice generator produces custom invoices in any language, handles included or excluded taxes such as VAT or GST, saves templates and exports to PDF. The Self Hosted Edition is free and open source, deployed from GitHub with Docker Compose, and the user brings their own keys for providers such as OpenAI, Gemini or Mistral. The Cloud Edition is a hosted version that supplies AI keys and storage on yearly subscription plans, with Early Access shown at 10 euros per month.
