Sales: Maintenance

A Budget-Friendly Plan

Software maintenance allows you to pay annually for your software in a budget-friendly way for the least disruptive method of staying current with IES software releases. Maintenance cost is approximately 15% of the new license price, but varies by product.

Maintenance is included for 1 year with your initial purchase. An automatic payment plan is set up with an online purchase, but you may cancel this at any time or pay manually.

Maintenance Benefits

  • Get major new versions at no extra charge (just download and install)
  • Stay current with design specifications and building codes
  • Receive bug fixes and updates
  • Obtain the best technical support answers and fixes
  • Allows you to move your licenses around to different machines or employees
  • Gain improved software reliability, performance and functionality

Maintenance is Optional, But Recommended

Paying annual maintenance is the lowest-cost way to use our products. Technically, you do not need to pay maintenance fees. Previously installed and activated products will continue to work "indefinitely". There are risks and costs associated with letting your maintenance expire:

Expiration Risks

  • You cannot activate expired licenses on new machines.
  • There is a $50 service charge to reinstate expired maintenance (within 30 days).
  • After 30 days, you would need to upgrade your license, see below.
  • You may not be able to enable on a repaired machine (e.g. hard drive failure, or OS upgrade).


If licenses expire, you no longer receive access to new upgrade versions, and technical support will be limited.

Should you later wish to upgrade, you may do so either through the self-service portal or by contacting our office. The cost to upgrade is 3x one year's current maintenance. After upgrading you get the latest product-version and one year's maintenance.

Upgrades are not permitted if they have been expired for 2 years or more, you must purchase at new prices.
