Maintenance and Support Contracts

To renew your support contract, please email us at, contact us through the chat on the lower left of this page, or call us at 1-603-448-4990.

isee systems provides technical support and maintenance to customers who own a current technical support plan. All new non-student licenses include an annual support contract.

Maintenance includes access to all updates that are made available on the isee systems website and can be downloaded at any time.

Technical Support is provided by telephone or email and includes software installation support, troubleshooting, and general "how-to" questions. Our support team is available Monday through Friday, 9:00 am to 5:00 pm ET, except on holidays. For answers to commonly asked support questions, please see our customer support hub and our support FAQs.

Renewal and Reactivation: Maintenance and support contracts can be renewed yearly to stay current. If they expire, reactivation is required to continue the contract.


Stella Architect $759
Stella Professional $579
isee Runtime $45
Stella Simulator $2300

Volume Discounts will be added to eligible orders when the order/quote is created.

Reactivation Pricing: Reactivation includes both getting the software up to the current version as well as maintenance and support for the next year, starting from the day the contract is reactivated. The pricing for support reactivation is dependent on the number of months since the contract has expired. As the length of expiration increases, the cost to reactivate increases monthly.
