I just wanted to share how FABULOUS [Geoff] is and you should keep him for sure! I have had the best service and training from him in the last few days that it has sold me on keeping AccuZIP @ my new job. I was new to this software and learning in “trial by fire” mode and he got me thru it without any burns! He is amazing and deserves a raise, bonus, employee of year- SOMETHING BIG. I have dealt with the mail industry for about 30 years and never received this level of support and so positive. I am forever grateful and will suggest him and this product if asked. I am being very serious about his knowledge, skill, and interpersonal skill(hard to find these days).
