Installation Guide (for non-technical users)

Step 1: Run the executable

• Windows: double-click the .exe file.
• macOS: open the .app (if Gatekeeper shows a warning, open via Right click → Open).
• Linux: run the binary (you may need to mark it executable).

Step 2: Open in your browser

• The app will open automatically in your default browser.
• If it does not open, use the address shown in the app window (commonly http://127.0.0.1:5000).

Step 3: Start using

• No login and no online setup.
• Your invoices are stored locally on your computer.

Usage Guide

Create an invoice

• Click New Invoice.
• Fill in the required invoice and customer fields.

Add rows (line items)

• Use Add Row (or the equivalent button) to insert additional item lines.
• Enter item description, quantity, unit price, and any other required fields.

Save

• Click Save Invoice to store the invoice in the local database.

Preview

• Open Preview to confirm spacing, alignment, totals, and overall layout.

Print / Download PDF

• Click Print / Save PDF.
• In the print dialog:
  • Choose A4
  • Use Portrait
  • For PDF: select Save as PDF as the destination

Project Structure (simple explanation of folders)

• app.py: application entry point (starts the local server)
• templates/: HTML pages used by the app (UI and print layout)
• static/: static assets such as CSS, images, and screenshots (including static/screenshot/)
• invoices.db: local SQLite database file created on first run (stores saved invoices)
• requirements.txt: Python dependencies (for developers/build process)
• *.spec: PyInstaller build configuration (used to package the desktop executable)

Tech Stack

• Flask: local web application framework
• SQLite: local database for invoice storage
• HTML/CSS: user interface and print layout
• PyInstaller: packaging into a desktop executable

Print & PDF System

This system is built with print quality as a first priority.

• Optimized for A4 printing: designed to print cleanly on A4, portrait orientation
• Stable layout: spacing and alignment are structured for consistent results across printers
• Professional output: the preview reflects the final print/PDF layout so you can confirm before printing

Configuration (optional basic edits like company name)

Basic branding and wording can be adjusted if needed.

• Company name / tagline: update the values shown in the invoice header within the template files in templates/.
• Logo and visuals: replace image assets in static/ (if your invoice design includes a logo).

After changes, re-run the executable (or rebuild the desktop package if you are distributing a new version).

Known Limitations (keep minimal and professional)

• Local-only: invoices are stored on the same computer where the app is used.
• PDF generation uses the browser print engine: final PDF output depends on the browser’s print settings (A4/portrait recommended).

Future Improvements (optional)

• Search and filters for saved invoices
• Export/backup tools for invoice data
• Optional template switching for different invoice formats
