What is Invoice &?

Invoice & by Jaklens is a free offline Windows app for tracking invoices and expenses. It uses a local AI model (Qwen2.5) to scan PDF or image invoices and extract key details like vendor names, line items, and tax amounts—all without an internet connection or cloud dependency. Users can manually enter invoices, track expenses and income, and query their financial history through a private on-device AI assistant. Everything runs entirely on your Windows PC, with no account, subscription, or data leaving your device.

Application scenarios

  • Small business invoicing

    Track and approve invoices from vendors like AWS, with automatic OCR extraction of line items and totals.

  • Freelance expense management

    Manually log income and expenses, categorize by type (e.g., Rent, Technology), and view running totals.

  • Financial querying

    Ask the AI assistant natural-language questions like "What's my net balance this month?" and get instant answers.

  • Audit compliance

    Use the mandatory approval workflow with timestamped audit trails to review and approve invoices.

  • Multi-currency accounting

    Handle invoices and transactions in different currencies with separate ledgers for expenses and income.

  • Data privacy-focused finance

    Process sensitive financial documents locally without uploading to any third-party cloud service.

Core Features

  • AI Invoice OCR

    Upload PDF or image invoices and let the local Qwen2.5 model automatically extract vendor names, invoice numbers, line items, dates, and tax amounts.

  • Manual Invoice Entry

    Fill in invoice details manually—vendor, line items, dates, tax, currency—when no file is available, and it enters the workflow as a fully structured invoice.

  • Expense & Income Tracker

    Manage separate ledgers for expenses and income with category management, search, filtering by status and date, and running totals across your full history.

  • Multi-currency support

    Handle transactions in different currencies within the same ledger system.

  • Invoice Approval Workflow

    Review AI-extracted fields, correct errors, then approve or reject with a mandatory reason; every action is logged in a timestamped audit trail.

  • Invoice ↔ Transaction Linking

    Approved invoices link bidirectionally to tracker entries, preventing duplicate entries and allowing instant navigation between invoices and transactions.

  • Excel Export

    Export any filtered view of invoices or transactions to a formatted Excel workbook, including a dedicated line items sheet, with a native save dialog and no third-party upload.

  • AI Financial Assistant

    Ask natural-language questions about your finances; the context-aware chat assistant reads your live database at the start of each conversation and runs locally via llama.cpp.
