COMMERCIAL TERMS
License the deployment.
Keep the license.
Paid Zimphony licensing separates perpetual usage rights from ongoing update and support entitlement.
Per deployment
One commercial license covers one licensed Zimphony deployment—not each mailbox or domain.
Perpetual use
Your right to use the licensed software does not expire.
Support & Update
12 months included with new paid licensesNew paid licenses include 12 months of Support & Update. Renewal is optional and priced at 25% of the then-current licensed edition and capacity price. Active Support & Update provides access to eligible Zimphony software updates and covered support. If it expires, the existing licensed software continues to operate.
Not tied to a Zimbra version
Your Zimphony license remains valid when you upgrade the underlying Zimbra server. A new Zimphony license is not required. Compatibility remains subject to the Zimbra versions supported by the applicable Zimphony release.
Upgrade protection
Eligible same-deployment paid-license upgrades receive 100% License Upgrade Credit. Pay only the difference.

The credit applies to eligible paid-license upgrades on the same licensed deployment. It is non-cash, non-refundable, non-transferable, and cannot be combined across licenses or deployments. It excludes Support & Update fees. Upgrading does not reset the existing Support & Update expiration date. No downgrade refund applies.
Licensing follows the Zimphony deployment—not individual mailboxes or domains. A server, VM, or legitimate hostname change does not itself require another purchase. Multiple Zimbra mailbox servers require a Zimphony deployment and applicable commercial license alongside each mailbox server.
Review deployment architecturePAYMENT POLICY
Payment and license delivery
International payment options may include bank transfer, an approved online payment gateway, or USDT by prior agreement as manual settlement. License delivery starts after payment is verified.
Any applicable third-party processing fees are disclosed before payment or included in the quotation. For bank wire or USDT settlement, the customer is responsible for sender or network fees.
Online payment options are planned for international orders. Stripe is the preferred future candidate, with PayPal as a fallback, but no automated online checkout is live on this website.
LOCALIZED CUSTOMER NOTE
Thailand customer pricing
For customers in Thailand, Zimphony offers localized THB pricing with manual payment by bank transfer or PromptPay after quotation or invoice. Prices below exclude VAT and apply per Zimphony deployment.
Thai customers can contact Zimphony for package selection, deployment guidance, and support consultation. License prices exclude custom professional services unless explicitly quoted.

PRICING FAQ
Questions before you choose.
Commercial terms, deployment implications, and product boundaries in plain language.
Is Webmail Free really free?
Yes. Webmail Free is permanently free and production-usable. It has no expiry, registration requirement, or license key. It includes Zimbra Mail and Zimbra Contacts, with unlimited Active Mailboxes and domains from the Zimphony side.*
What is included with a new paid license?
New paid licenses include 12 months of Support & Update. Renewal after that is optional. Annual renewal is priced at 25% of the then-current licensed edition and capacity price.
Is Support & Update renewal required?
No. Annual Support & Update renewal is optional and separate from perpetual usage rights.
Which Complete Workspace capacities are public?
Native Zimbra and Google Connect use the same public capacity choices: 50, 100, 250, 500, and 750 Active Mailboxes. Deployments with 1,000+ Active Mailboxes are handled through Contact Sales.
What happens when Support & Update expires?
If Support & Update expires, the licensed software continues to operate. What stops is covered support and access to eligible software updates until Support & Update is renewed or reinstated.
How much does annual renewal cost?
Annual Support & Update renewal is optional. Annual renewal is priced at 25% of the then-current licensed edition and capacity price.
Can expired Support & Update be reinstated?
If Support & Update has lapsed and you later want to restore update and support eligibility, reinstatement for lapsed coverage may be quoted separately. Normal annual renewal remains priced at 25% of the then-current licensed edition and capacity price.
What happens after four missed renewal years?
For long-lapsed Support & Update coverage, Zimphony will confirm the available renewal, reinstatement, or new-license path before payment. Normal annual renewal remains priced at 25% of the then-current licensed edition and capacity price.
Do I need to reinstall Zimphony after renewal, reinstatement, or purchasing a new license?
Renewal, reinstatement, or purchasing a new license does not require reinstallation or mail-data migration.
Is source code included with the standard license?
No. The standard license does not include the original development source code. The Python backend is compiled using Nuitka, while the frontend is delivered as production build files. As with browser-delivered software, frontend JavaScript and CSS may be technically inspectable, but these files are not the original development source code. Use, modification, reverse engineering, and redistribution remain subject to the license terms and applicable law. Original source code or additional source-code rights may be available under a separate commercial agreement; contact Sales to discuss your requirements.
Do I need a new Zimphony license when I upgrade Zimbra?
No. Upgrading the underlying Zimbra server does not itself require a new Zimphony license. Technical compatibility remains subject to the Zimbra versions supported by the applicable Zimphony release.
