All processing happens locally on your device, ensuring complete privacy and security of your business information.
What file formats are supported for data import?

Can I use this tool on mobile devices?

How does the tool integrate with WordPress?
▼
The tool is designed to inherit your WordPress theme's styling automatically. It uses CSS that adapts to your existing color scheme, typography, and layout without modifying your WordPress installation. Simply embed the HTML file in a page or post, and it will blend seamlessly with your site's design.
Can I customize the invoice template?
▼
The tool provides a professional, clean invoice template that works well for most businesses. While the current version focuses on functionality and WordPress integration, the code is structured to allow for easy customization of colors, fonts, and layout elements if needed.
What currencies are supported?
▼
The tool supports major international currencies including USD ($), EUR (€), GBP (£), JPY (¥), CAD (C$), and AUD (A$). The currency symbol will automatically appear in all monetary calculations and the final invoice display.
How do I save my invoices?
▼
You can save invoices in multiple ways: download as a PDF file for digital storage and sharing, print directly from your browser for physical copies, or use your browser's save function to keep the HTML version. Since no data is stored on servers, we recommend saving important invoices locally.
Can I add my company logo to invoices?
▼
The current version focuses on text-based professional invoices for maximum compatibility and loading speed. However, the tool's structure allows for easy addition of logo functionality in future updates or through custom modifications to the HTML code.
Is there a limit to the number of invoice items?
▼
No, there's no hard limit on the number of items you can add to an invoice. The tool dynamically adds rows as needed and handles calculations for any number of items. However, for very large invoices, consider breaking them into multiple invoices for better readability.
Does the tool work offline?
▼
Yes! Once the HTML file is loaded in your browser, the tool works completely offline. All functionality including calculations, file processing, and invoice generation operates without requiring an internet connection, making it perfect for use in any environment.
