Be sure you make use of the help and support built into the software. This document can be searched, and you should try different potential terms, sometimes less is more when searching (use just the unique word or words). A Table of Contents is also available.
Email Support: support@iesweb.com. Replies are usually within 2 business hours, if you don't hear anything within a day, assume it got spam filtered or lost and follow-up. For best results, be sure to ask a question, indicate exactly which IES product & version you are using, include as much detail as is practical or relevant, including attaching a project file.
Telephone Support: Not Available. We have found this to be too inefficient for everybody. With email you can attach a screen shot, a project file, and we can better direct your question to the IES expert for that product or area. Phone 'tag' takes longer than you think.
Business Questions: For any licensing or sales-related questions or issues: sales@iesweb.com.
