  • I wanted to take a minute to tell you how much we love the GT-400 (hand punch) time clock and the service received from IEC. If there were any issues or questions with the hardware or the website, your company has been quick to resolve the problem. Your dedication to customer service has not gone unnoticed. We are pleased to be partnered with IEC and would recommend your company to anyone looking for good service.

    Thank you for all you have done for us over the past ten plus years.

    Fred Hetzler President Eureka Foundry

    “Ease of use of the program and the Guys that SUPPORT it. (Of all the programs I have they provide the Best Support) ex: Our time clock broke (someone pulled it off the wall) and Bob and his guys had us a temp replacement here the next morning and up and running shortly after we unpacked it and then had our old clock repaired and back to us in no time. The support that Bob and Dave and the rest of the guys have provided is top-notch and the system has performed great.”

  • I’ve worked with “another time and attendance vendor”* and their VARs a lot in the past 10 years, and getting anything tweaked or improved is either impossible or takes an unreasonable amount of time and money. I’m really impressed with your group and AoD.”
