If just the thought of getting on the phone with tech support makes your blood boil, you’re not alone. Ninety percent of people surveyed in a recent Harris Interactive poll said they’ve had a bad experience with tech support, and 85 percent of respondents said they’ve sworn, shouted, cried or hit something in frustration because of bad customer service. I’m not proud of it, but I know I’ve fallen into that category before.

So if you create a tech product, what can you do so bad tech support doesn’t sink your business? Make sure you have your tech support systems in place before you launch and make sure the people providing support are trained well. Test your product thoroughly, and make sure you design it well. And post troubleshooting FAQs on your website so customers can deal with common problems themselves.
