Smart Invoices - Bill Tracker

Smart Invoices lets you photograph or import paper invoices and bills, extract all the data automatically with AI, and keep a searchable archive on your phone — with groups, statistics, PDF export, and Google Drive backup. WHY USE SMART INVOICES Paper invoices pile up fast. Smart Invoices turns a quick photo into a structured record: vendor, invoice number, dates, line items, amounts, payment status. No manual typing. No cloud account required for core features. CAPTURE & AI EXTRACTION • Add invoices four ways: the in-app camera, the built-in document scanner, your photo gallery, or a PDF • Import several photos at once — each invoice is reviewed and saved in turn • Import straight from a PDF — the first page is read into the app, no screenshots needed • ML Kit OCR reads the text on-device first — no data leaves your phone unless you choose AI • If OCR confidence is high, a lightweight text-only AI call extracts the fields • For complex layouts the full vision AI is used as fallback • Intelligent fallback — if AI extraction is incomplete, an offline heuristic parser reliably extracts vendor, amount, and currency without using AI • Customize the AI extraction prompts in Settings, with one-tap reset to defaults • Works with Gemini (1 500 free requests/day) and Groq (14 400 free requests/day) — you bring your own free API key • Review and edit any extracted field before saving INVOICE MANAGEMENT • Full invoice list with vendor name, amount, currency, due date and payment status • Currency auto-detection based on your device locale (EUR in Europe, GBP in UK, etc.) • Mark invoices as Paid, Unpaid, or Overdue • Edit any invoice manually — line items, tax, discount, notes, payment method • Soft delete with recovery — nothing is permanently lost by accident • Full-text search across vendor name, invoice number, and notes • Attach and view the original photo full-screen GROUPS & STATISTICS • Organise invoices into named groups (by client, project, or period) • Per-group summary: total, paid vs unpaid split, invoice count, per-currency breakdown • Group detail view lists all member invoices PDF EXPORT • Generate a PDF report for any invoice group • Formatted table with line items, totals, and payment status • Share via email, Google Drive, or any app GOOGLE DRIVE BACKUP • Back up your entire invoice database to your Google Drive app folder • Backups are AES-256-GCM encrypted on-device before upload • Restore with one tap — app restarts cleanly after restore • Optional auto-backup: daily or weekly, runs only when connected PRIVATE BY DESIGN • No account required to use the app • All data stays on your device • AI calls are direct HTTPS requests to the provider you choose — no intermediary server • API keys are stored in Android Keystore, never logged or shared • Google Drive backup is stored in your personal app-data folder, invisible to other apps WORKS WITH Any invoice or bill: retail receipts, service invoices, utility bills, contractor quotes. Supports any currency and any language that ML Kit can recognise. REQUIREMENTS • Android 9.0 (Pie) or higher • Free Gemini or Groq API key for AI extraction (optional — manual entry always works) • Google account for Drive backup (optional)
