Key Features

  • Create, send and manage invoices and estimates with configurable PDF templates and a template generator/CLI.
  • Expense and payment tracking with attachments and categories, plus dashboard stats for revenue and cashflow.

  • Recurring invoices support (API endpoints for scheduling and frequency control) and custom fields for extended data on models.
  • Customizable PDF templates (blade-based) with a make:template command to preserve templates during upgrades.
  • Installer and deployment options including manual install guides and Docker Compose instructions; configurable database drivers (SQLite used as default in examples).

Limitations and Considerations

  • Hosted mobile apps are not universally available; mobile app source code exists but official app availability is listed as "coming soon" in project notes.
  • Built-in payment processing is not bundled by default; payment integrations (e.g., Stripe) are listed on the roadmap rather than fully integrated out-of-the-box.
  • Installation requires familiarity with PHP/Laravel environment requirements (PHP 8.2+ and typical PHP extensions) or Docker tooling for easier deployment.

InvoiceShelf is a practical open-source alternative for self-hosted invoicing, with an extensible codebase and API-first design that supports customization and integrations. It is maintained as an AGPL-licensed project with community contributions and documentation for installation and developer workflows.
