SigmaXL Support Policy

Upgrades
Upgrades are released when new functionality or enhancements are added and are provided to users with perpetual licenses free of charge for one year following the initial purchase date.

Optional maintenance renewals may be purchased prior to the expiry of the first year for 20% of currently listed retail prices.  Maintenance renewals entitle our customers to continued upgrades and technical support. 
For perpetual educational licenses, maintenance costs are set at $59.80 per SigmaXL license and $160.00 per DiscoverSim license. Users without an active maintenance plan can still purchase upgrades at a 50% discount off the currently listed retail price.

Technical Support
FAQs and solutions to common error messages can be found on our Help Desk.

We also provide technical support via phone at 1-888-SigmaXL (744-6295) and email at support@SigmaXL.com from 8:30 am to 5:00 pm ET Monday through Friday, excluding CDN statutory holidays. Live help is available on our website during the same hours. Our Live Help availability is always indicated on the top right hand corner of our site.

Support is provided free of charge to those with a valid maintenance plan. Licenses not covered by a valid maintenance plan are not entitled to priority support. Users will receive a response to their request within 7 to 10 business days.
