You can define your own templates for your documents, which will be created in LibreOffice. Furthermore, you can connect to your web shop and get all orders, customers and products for easy management in Fakturama. If you want to create parcel label, Fakturama helps you in for creating it (fills out the online web forms of several parcel service providers).

enXure is a self-hosted invoicing and recurring billing app for agencies and freelancers who want to own their billing data instead of renting it from a SaaS. Create invoices and quotes that convert to a real invoice in one click, with recurring billing that runs automatically on each client's own schedule, Stripe/PayPal or manual payment collection, and an optional client portal so clients can view invoices and accept quotes with no login of their own.

Fully brandable (logo, color, white-label mode), with TOTP two-factor auth, a searchable audit log, one-click backups, and a REST API plus Slack/Telegram notifications.

Free and open source (AGPL-3.0) — every core workflow works with no license key; an optional paid license unlocks Stripe/PayPal, recurring billing automation, the client portal, the API, and a few other extras. One container stack (PHP, MySQL, nginx), no Node build step: docker compose up -d --build and you're running.
