Welcome to the New Simple Invoices

We're excited to announce a major refresh of Simple Invoices: the open-source invoicing platform trusted by businesses worldwide since 2005.

What's New

Modern UI with Tabler

The entire interface has been rebuilt with Tabler CSS, a modern Bootstrap 5-based framework. The result: a cleaner, faster, and more responsive experience on desktop, tablet, and mobile.

Laravel Blade Templates

Invoice templates now use Laravel Blade: the same templating engine used by millions of Laravel developers. This means easier customisation and better performance.

PHP 8.1+ Compatibility

Full compatibility with modern PHP versions (8.1, 8.2, 8.3, 8.4). The Zend Framework 1 Future fork and PHPMailer 6 ensure your stack stays current.

Docker Deployment

Get up and running in minutes with the new Docker image. Includes PHP-FPM, Nginx, and support for MySQL, MariaDB, PostgreSQL, and SQLite.

Multi-Domain SaaS

Run multiple isolated invoice domains from a single installation. Perfect for SaaS platforms, multi-brand organisations, and regional offices.

Rspress Documentation

The new documentation site (you're looking at it!) is built with Rspress: a modern static site generator with search, RSS feeds, and a responsive design.

What's Next

  • Expanded API for integrations
  • Enhanced reporting and analytics
  • More payment gateway integrations
  • Improved multi-language coverage

Stay tuned for more updates. As always, Simple Invoices remains free and open-source under the GPLv3 license.
