Rubrol Pro and Rubrol Enterprise are commercial extensions and licensing agreements for the Rubrol engine. They provide commercial SaaS rights that replace the GNU LGPLv3, private GitHub template vault access, cryptographic 1-year offline license keys, turnkey European e-invoicing compliance (Enterprise), and direct developer support.

We do not offer pre-sales sales demos or trial keys. Rubrol Community is 100% free, open-source, and available on GitHub under GNU LGPLv3 for evaluation and local development. If Rubrol works for your architecture, you can purchase an annual subscription to Pro or Enterprise. If you are not satisfied with the result, write to support@rubrol.com within 14 days and we will issue a full refund.

For Rubrol Pro ($1,800/yr), pricing is flat and transparent with zero discounts or promotions. For Rubrol Enterprise ($4,800/yr), multi-year commitments or custom cluster volume agreements are available for high-throughput organizations. Email enterprise@rubrol.com for custom quotes.

The open-source core is licensed under the GNU Lesser General Public License v3.0 (LGPLv3). Rubrol Pro and Enterprise are commercial licenses that replace the LGPLv3 with a traditional proprietary agreement for production SaaS deployments, removing open-source linking obligations.

Every organization running Rubrol in production for commercial SaaS applications must purchase an annual subscription ($1,800/yr). There is no limit to the number of Docker containers, Kubernetes pods, CPU cores, or developer machines used by that organization. Your subscription renews automatically each year.

Every organization deploying Rubrol for European e-invoicing compliance (EN 16931) must purchase an Enterprise subscription ($4,800/yr). It includes certified ISO 19005-3 PDF/A-3b container generation, embedded Factur-X / ZUGFeRD 2.2 XML, built-in Schematron semantic validation (XRechnung 3.0), French Chorus Pro and German DIN 5008 templates, dual vault access (rubrol-pro-vault + rubrol-enterprise-vault), 2025-2028 regulatory updates, and priority Slack/email support.

You can purchase in seconds via Stripe Checkout:

• Buy Rubrol Pro ($1,800/yr)
• Buy Rubrol Enterprise ($4,800/yr)

Enter your GitHub Username during checkout. You will automatically receive an invitation granting access to the private template vault, and a signed 1-year cryptographic license key (RUBROL_LICENSE_KEY=RBL-LIC-...) will be issued immediately.

Yes. Purchase a Rubrol Enterprise subscription and email support@rubrol.com. We will cancel your existing Pro subscription and prorate the unused balance back to your credit card immediately.

We email you an automated reminder one week before annual subscription renewal. If your card cannot be charged, Stripe retries 3 times over a 7-day period. If payment continues to fail, your subscription is canceled, private GitHub vault repository access is revoked, and your offline license key will not be renewed upon expiration.

The standard commercial license covers your organization's own SaaS infrastructure and internal servers. If you need to distribute Rubrol binaries or containers embedded directly inside an on-premise software appliance delivered to external third-party customer hardware, contact enterprise@rubrol.com for an OEM Appliance License.

Licenses are not transferable between different corporate entities. You can transfer a license between employees or GitHub accounts within the same organization by emailing support@rubrol.com with your Stripe customer email.

Your purchase provides private GitHub vault repository access and an offline cryptographic license key. The license agreement requires you to keep these access credentials confidential. Do not commit your license key to public git repositories or public container registries.

Yes. Your developers and CI/CD runners require the RUBROL_LICENSE_KEY environment variable to compile production documents without evaluation limits. Store it securely in your secret manager (e.g. AWS Secrets Manager, GitHub Actions Secrets, HashiCorp Vault, Doppler, or local .env).

Ensure your environment variable RUBROL_LICENSE_KEY starts with RBL-LIC-. Run rubrol license verify from the CLI or inspect container logs on startup. If the key has expired or the signature was modified, the engine will output a clear error message indicating whether the token was malformed or expired.

Yes, up to 14 days after purchase. If Rubrol does not fit your infrastructure or workload, write to support@rubrol.com and we will refund 100% of your payment.

Rubrol Pro is credit card only via Stripe. For Rubrol Enterprise, annual invoicing with payment via ACH, wire transfer, or corporate purchase order is available for qualified corporate accounts. Contact enterprise@rubrol.com to arrange an invoice.

If an unfamiliar charge appears on your card statement, please contact support@rubrol.com before initiating a bank dispute. Disputes result in immediate automated suspension of license keys and vault access. We resolve billing issues and refunds quickly and politely.

Rubrol runs 100% locally within your own Docker containers, Kubernetes pods, or bare-metal servers. Customer documents, invoice data, and PII are processed entirely in memory and never leave your infrastructure. There are zero outbound document telemetry calls, zero third-party analytics scripts, and zero cloud dependencies.
